Taijie WEBOX 20C experience: TV box with both appearance and practicality

In the past few years, with the rapid development of the mobile Internet industry, smart phones have become an important part of our lives. From the ubiquitous “bow families” we can perceive people’s dependence on smart phones, and many interesting and playful The application is the greatest attraction of smart phones, and it is also the main reason why we gradually form dependence.

However, in recent years, innovations in smart phones have shown signs of fatigue, and fewer and fewer revolutionary innovations have been made. Major manufacturers have also begun to target the hardware ecology beyond mobile phones in order to quickly seize the opportunities and carry out the next phase of ecological layout. Among them, smart home is a big cake that attracts much attention. When it comes to smart homes, occupying the living room is the direction that the giants have been aiming for over the years. From Sony’s Nintendo’s video game consoles to Xiaomi’s box, Apple TV, and various smart TVs, etc. It is the most important part of smart home, because it is the third screen in addition to mobile phones and computers.



Like mobile phones, smart TVs and TV boxes can also experience a variety of interesting applications, thus changing the original value of television and creating new games. In recent years, the digital tail has also shared many smart TV and TV box experiences. This time, what we will bring is a small and unique TV box. It is the WEBOX 20C from Tate.



When talking about Taijie, there may be some tails that are not well understood. Taijie’s converged video service has many users. Together with Tencent’s strategic investment, Taijie’s WEWARE box series of hardware products has been developed into three products. This is the WEBOX that we have shared experiential text; the second is the WEBB WEB 20C with enhanced performance and supports H.265 and 4K playback; the third is the protagonist of our experience text WEBOX 20C. Two products, it is a very small size, almost a coaster size.



What kind of box is a good choice for tails who have not purchased smart TVs at home? If you hope to see this article, you will have a brand new choice.

The face value is the characteristic of the current TV box

First of all, let's take a look at the exterior design of the Tektronix WEBOX 20C. It does not use the popular black main tone, but the whole body of snow white plus a transparent plastic shell covering the surface, making it look and people in the TV box. It's different.



However, because the outer layer of the box is wrapped with plastic material, it will be easier to produce subtle scratches, which may be the reason why the product uses white tone, because the scratches produced on the surface must be carefully read under the white tone to find out.



Although the TV box does not need to be used outside the mobile device, but as a product placed in the living room, and traditional home appliances, the design is more concerned about whether the appearance of the product is consistent with the user's home decoration style, although the appearance of Does not affect the use of the experience, but it can look more pleasing to the eye that the user will not refuse.

Taige WEBOX 20C only palm-sized body, snow-white machine with a transparent material shell, so that it looks a little crystal clear feeling, round the front of the fuselage printed WEBOX's LOGO. With the TV box running, the LOGO will emit blue and green light.



Hardware Interface: Sparrow is small, fully-equipped

As mentioned in our article earlier, Tage also has a performance-oriented WEBOX 20S that supports 4K playback, H.265 decoding, and more. This time, the WEBOX 20C has a clear preference for entry-level hardware configuration. However, from our actual experience, it is also able to meet most of the use requirements.

In terms of interfaces, the WEBOX 20C's interfaces are all set behind its round frame, ensuring a positive appearance. What deserves to be mentioned is that, thanks to the USB interface criticized by box users, Taijie has given it plenty of space. If there are some odd-shaped or large-sized USB devices in the tail, there is no need to worry about the possibility of failure. La. In addition, WEBOX 20C supports Bluetooth 4.0, so if a USB interface is not enough, you can also use Bluetooth to connect other wireless devices, such as Bluetooth mouse, handle, and so on.



In addition to the necessary HDMI, power, and USB interfaces, the WEBOX 20C also has a 3.5mm AV output jack for older TVs, making it easy to use older TVs with only AV ports.



Compared with the first generation of WEBOX, the remote control of WEBOX 20C did not bring improvement. The design was quite satisfactory. The streamlined back effectively improved the grip, and the arrow keys had a bump design, even if you did not deliberately look at the remote control. Can also be accurate operation, be considered a more intimate place. In addition, this remote control's work is not particularly satisfactory. It will not be easy to use a variety of scratches after a long time, and it will easily leave a hand mark.

As the most important accessory of the TV box, the WEBOX 20C's remote control has taken a lot of effort. It is equipped with a wireless remote control instead of an infrared remote control. It adopts a 2.4GHz Wi-Fi transmission method. Compared with the Bluetooth remote control, the biggest advantage is that it doesn't have to worry about distance problems during operation, or the presence of obstructions affects the operation instructions. In the 60-flat house in my house, there was no reaction insensitive situation when the remote control was used to fill the room.



Of course, you can control the WEBOX 20C by using a mobile remote control application like other TV boxes, but the actual experience is definitely not as fast as the physical remote control.

Content is the real battlefield for TV boxes


Returning to the issue of how to watch television, the most important thing is to choose a TV box. Its main source of video resources is the television network. Currently, the mainstream operators in the TV box are Mango TV, Hwasa, CIBN, etc., all of which are rich in quality. The network video resources, while the operator's differences determine the difference in its content. The WEBOX launch is equipped with Tencent CIBN broadcast control, content coverage is broader, basically users of different ages at home can also find suitable video resources.





Extensive and comprehensive performance, slightly bottlenecks in performance

On the TV box, in addition to the content provided by the broadcast control, the WEBOX 20C also provides a LAN file sharing function that can share the movies stored on the computer. Watching movies on your computer on your TV, including installing apps, playing music, etc. can be done this way. However, tails who are accustomed to using USB external devices can also play USB media files on the WEBOX 20C via a USB connection. However, it is somewhat puzzling that the WEBOX system did not provide the ability to remove the device after the USB device was inserted.



Judging from the actual experience, the performance of WEBOX 20C can only be counted. The playback of 1080P full HD MKV video will result in dropped frames. The same is true for online playback of 1080P video quality. The main manifestation is that the picture is not smooth enough. But if you do not compare carefully, it will be more difficult to find. For most of the ultra-defining video quality of online video, WEBOX 20C can easily perform the task, fully realize smooth playback and no stalling phenomenon. Therefore, in general, WEBOX 20C still can meet the needs of most environments.

In addition, since the WEBOX 20C only supports 2.4GHz Wi-Fi, it will have a lot less speed in the transmission of LAN speeds and LAN files. If the next generation of products can support 5GHz Wi-Fi, it is believed that the network experience will be even better.



WEBOX 20C system is based on Android 4.4.2 depth customization, comes with the application of a "my album", just open the phone's WeChat scan the two-dimensional code on the TV to complete the device binding, after the success can be achieved Send the picture taken by the mobile phone to the "Thai Assistant" public number, and then "Thai Assistant" will push the sent picture to WEBOX 20C.

There are many ways to play this feature, which first appeared in Huawei's glory box. If you bought WEBOX for your distant parents, you can push your own photos to the box later, so that parents can also see your newly shared photos. This is a warm game that this function can achieve.



Phone pictures pushed by "Tai Jie Assistant"

Click on the WeChat TV under the assistant's assistant to see quick searches and various TV shows and movie recommendations. In terms of experience, using mobile phone input method to search is much simpler than using the TV box input method, and it can be considered as a "curve saving country" method for TV input method. When the desired program is searched for, the program can be pushed to the TV box with just a click.





Use WeChat Scan to Bind the Phone to the TV Box



Even if you are outside, you can push videos to your home remotely via the "Thailander"

The pushed video will first appear on the top of the TV alert, and then enter the interface of the video optional resources. After waiting for parsing and loading, it will enter the playback. The response speed of the entire process is still fast.



For young children, more interactive games may make them more interested. At this time, you may need to open up a special area for children.

The children's model of WEBOX 20C is set to deal with this situation, in which there are many interactive puzzle games to meet your child's customer entertainment. If your child is a little older, you can find a kid-friendly puzzle game on the built-in Tencent game lobby like "Cool Run" and "Plant vs Zombies." However, due to the poor performance of the hardware, games like “Cool Run” will occasionally appear to be stuck with Caton, causing the game to fail. The experience is not ideal. You can only play with works that do not require high performance.





Deep integration of Tencent Eco WEBOX, the final performance?

In the TV box, this already hot Red Sea market, there are already many brands based on this, and WEBOX itself as a good polymerization platform, it is reasonable to launch a TV box, but there are still many improvements in TV boxes. Space.

Judging from the performance of WEBOX, we can also discover that this is a TV box with Tencent Ecology. For example, Tencent video is used for broadcast control. Some built-in interactive games are also from WeChat under Tencent. The games are integrated. Tencent video game platform. The bottleneck of performance is the biggest flaw of this product. As mentioned in our article, it is more suitable for users who are pursuing compact and portable design. If you prefer performance and full HD, 4K image quality, then It is more suitable to choose another WEBOX 20S WEBOX.



Of course, in the final analysis, the most important thing for a TV box is content. As long as there is a huge advantage in content, users will naturally pay for it. With the current TV box, the content advantages of each individual are not obvious, and the resources are different. The user experience is difficult to reach a very good height. As a user, we can't just look at a video site.

If only relying on its own broadcast control is completely unable to meet the demand for film sources, for the tail of the TV box that has been purchased, I believe it should be very clear how to break the restrictions on film sources. Only with proper tossing and cracking can we gain a huge content world. At this point, WEBOX 20C can easily install downloaded applications and it also means that the threshold for acquiring resources is lower. When you install a variety of video playback applications, you will find that the content of your own broadcast control is not as good as it is. Looking at Youku and Sohu on the box, I won't tell you how cool it is!



Therefore, standing on the point of use of a TV box to use a recommendation, individuals will suggest that the tail is more to consider the use of the product experience, such as the fluency of video playback, rather than pay attention to their own broadcast control film Whether the source is rich or not, as mentioned earlier, enrichment cannot fully satisfy our needs. Therefore, the use experience of the product and the appearance design are the priorities that we need to pay more attention to.

The WEBOX 20C is aesthetically pleasing in appearance, and it is a pretty good decoration next to the TV. In terms of hardware configuration, the problem of lack of experience due to insufficient performance is also not negligible. Therefore, it is also necessary to judge according to your own needs when purchasing.

The greatest value of the TV box is always to expand the function of ordinary TV. It is more to pull us back from the computer and mobile phone to the living room. After all, the visual experience brought by watching the program on TV is always better than the computer. .

What is Multilayer PCB

Definition of Multilayer PCB Circuit Board

The multilayer PCB came into being due to the evolving changes in the electronics industry. The functions of electronics have become progressively more sophisticated over time, requiring more complex PCBs. Unfortunately, PCBs were limited by problems like noise, stray capacitance and crosstalk, and therefore needed to follow certain design constraints. These design considerations made it difficult to get a satisfactory level of performance from a single or even double-sided PCB - thus the multilayer PCB was born.
multilayer PCB
The definition of multilayer PCB is a PCB that is made with three or more conductive copper foil layers. These appear as several layers of double-sided circuit boards, laminated and glued together with layers of heat-protective insulation between them. The entire construction is arranged so that two layers are placed on the surface sides of the PCB to connect to the environment. All electrical connections between the layers are achieved with vias such as plating through holes, blind and buried vias. Application of this method then leads to the generation of highly complex PCBs of varying sizes.

Why Do We Need Multilayer Circuit Boards?

Multilayer PCB is an integral part of most of the electronics when it comes to connecting number of electronic components on the board. Multilayer PCB helps us getting rid of the old ways of joining components where components were joined together by end to end wiring, resulted in covering more space and weight and unable to fulfill the requirements of more complex designs. Experts are in constant struggle to improve electronic design with compact shape so it provides better user experience and turns out to be less costly than its predecessors.

Now, you have got a clear idea why do we need PCB. There are already different types of PCB Board available in the market i.e. single layer board and double layer board. But, sometimes these boards fail to deliver more complex designs because of availability of less number of conductive layers on the board. Technology is evolving with the greater need of making devices cheap and low weight so they can meet the requirements in less cost and capable of performing more functions than using conventional ways of making electronic devices.

Multilayer Circuit Board Can Simplify The Design

Multilayer PCB boards came into play with the intention of constructing more number of conductive layers on the board than single-layer or double-layer boards. Multi-layer boards come with a combination of single-layer or double-layer board and give opportunity to connect more electronic components in less space. These boards are made with number of conductive layers with insulated material between them. Multilayer boards are mostly developed in rigid form, because making multilayer board in flexible form is very difficult to achieve and it also results in more cost than rigid boards. Instead of using flexible multilayer boards, most of the professionals prefer using combinations of single or double sided board that are very effective in most of cases and are cheaper than multilayer flexible boards.

Development of Multilayer PCB Board totally depends on customers'demands. With the invention of new technology multilayer circuit boards can be manufactured with up to 100 conductive layers, making complex design where more number of components are joined together. Smartphones are a great example of multilayer PCB that gives a benefit of performing more functions using single board. This refrains from spending more money on the combination of single sided or double sided boards, because they cost heavily with no guarantee of fulfilling requirements as multilayer PCB.

Multilayer PCB Board Fabrication

Multilayer boards can be manufactured with even conductive layers or odd conductive layers on them. However, it is recommended to use multilayer PCB with even layers because it results in simple design and helps in joining number of different components on the board where board design with odd layers can be costly and pertains to complex design, making it difficult to join number of electronic components on the board. Also, design with odd layers makes it very difficult twisting the board during execution of project, as odd layers are not equally distributed over the whole board structure which can damage the boards when they are subject to under heavy weights.

Some multilayer boards are manufactured so closely, making it very difficult of you to count the total number of layers with naked eye. However, still you can guess total number of layers based on the layers pattern and how they are laminated on the board. Number of different conductive layers on the multilayer boards can be termed as signal, power or ground planes. Power or ground planes are directly proportional to the number of voltage requirements on the board, if there is a need of more than voltage supply on the board, then multilayer boards come with more than one power or ground planes.



The difference between single-layer PCB, Single Sided PCB , and multi-layer PCB


Single Layer PCB vs multilayer PCB


When it comes to Printed Circuit Boards, an immediate question before design is whether to use single or multi layered PCBs for your circuit. The benefit and use of each depends entirely on what you`re intending to do. First we should define each type of circuit board.

Single layer or single sided PCB


These PCBs simply have components on one side of the board and the conductor pattern on the other side. This reason is why it`s known as a single sided or single layer PCB. Often, these are used for simpler devices as no wires can cross if the circuit is to function correctly. These are usually slightly cheaper to manufacture than multi layer PCBs.



How to identify a multilayer PCB


If you have some PCBs to hand and you`re interested in how many layers it uses, there is a way to see without causing damage to the board itself.

Firstly, shine a light into the edge in an attempt to see the copper planes, this may result in you seeing the signal traces. This will only work if the copper comes close to the edge however.

Using some sort of bright light source again, we can see if a board has inner layers even if doesn`t have blind vias. The best place to do this is [where there aren`t traces/planes on the visible, outer layers-" The areas where it`s blocked are usually copper.

Some companies or manufacturers are known to label the individual layers on the board itself, so check around the edges for numbers.



How Are Multilayer PCBs Fabrication?


Packing the power of a double-layer PCB into a format that's a fraction of the size, multilayer PCBs are becoming increasingly popular in electronics. They come in a wide range of sizes and thicknesses to accommodate the needs of their expanding applications, with variants ranging anywhere from four to twelve layers. Layers most often come in even numbers, since odd numbers of layers can cause issues in the circuit like warping, and are no more cost-effective to produce. Most applications require between four and eight layers, though applications like mobile devices and smartphones tend to use around twelve layers, and some professional PCB manufacturers boast the ability to produce multilayer PCBs with nearly 100 layers. Multilayer PCBs with that many layers are rare to see, however, as they are extremely cost-inefficient.

  • Specialized equipment for pressing multilayer


PCBs Manufacturing multilayer PCBs requires a specialized hydraulic press with heated platens. Initially the books are squeezed with a [kiss" pressure of 50 psi prior to being heated to 350F at 350 psi for a minimum of one hour. The assembly is then allowed to cool slowly before removal for further processing. At Omni, the maximum size of a multilayer board is 12"x 16" while the board thickness can range from 0.015"to 0.125".

  • Multilayer PCBs Fabrication Process


The outer layers of multi-layer consist of sheets of glass cloth pre-impregnated with uncured epoxy resin (prepreg) and a thin copper foil.

The lay-up operator has already placed a copper foil and 2 sheets of prepreg on the heavy steel baseplate.  Now he places the pre-treated core carefully over the alignment pins.  Then he adds 2 more sheets of prepreg, another copper foil and an aluminium press plate

He builds up 3 panels on the baseplate in the same way.  Then he rolls the heavy stack under a press which lowers down the steel top plate.  He pins the stack together and rolls the finished stack out of the clean room into a rack.

The press operator collects 3 stacks on a loader and loads them into the bonding press.  This press uses heated press plates and pressure to bond the layers of the PCB together.  The heat melts and cures the epoxy resin in the prepreg while the pressure bonds the PCB together.  The process is computer controlled to build up the heat and the pressure correctly, hold it and then to cool the press down.  In this way we ensure a permanent bond that will last the lifetime of the PCB.  Our board has 4 layers but complex PCBs for defence, avionic and telecommunications applications can have more than 50.  These may include sub-assemblies of cores, prepregs and foils drilled and plated before being assembled into the final PCB.

Once the cycle is completed the press operator unloads the press and carefully rolls the heavy stacks into the clean room.  Here the lay-up operator de-pins the stack and removes the top plate.  He unloads each of the panels from the stack, removing the aluminium press plates used to ensure a smooth copper finish.  The copper foil is now bonded in place to form the outer layers of the PCB.



Design for Manufacturability (DFM) for multilayer circuit boards


PCB design plays an important role in determining the mechanical,electrical and thermal performance of the complete electronic system. Many advanced electronic components use multilayer PCB, because it allows large number of components to incorporate on a single board, hence allowing the higher component density. Some PCBs are highly complex that make use of electronic components that are embedded on the substrate material.

Signal integrity and power integrity are two important features you must take into consideration before you intend to make PCB layout design. You must adopt following rules in order to maintain complete power integrity and signal integrity of the PCB.

Multilayer board design must take into account the components used in later assembly.

  • Conductive PCB trances are composed of copper that comes with finite resistance. Voltage drop in many digital systems can severely influence the quality and accuracy of the system at that resistance when small current flows through the system. Controlled impedance trances are required in order to maintain the high accuracy of the system.


  • If significant current flows through the board, it exceeds the temperature beyond normal value because of the resistance of trances.In order to control board temperature and increase PCB reliability, the width of the trances must be increased, which, if not possible due to the overall predefined circuitry, then copper thickness must be increased to 2 to 3 based on your needs and requirements.


  • Stray inductance can cause voltage spikes on the board which can be handled by using the decoupling capacitors near load.


  • Magnetic field is generated when current passes through the traces. This magnetic field can harm or influence the compoents that come under the range of magnetic field. To avoid this process, components must placed with larger space between them which is near to impossible in case of multilayer compact design. So, alternative way to overcome the affect of magnetic filed is to add return path or ground plane. A ground plane will behave like a shield and helps in providing a return path of any signal. Ground planes generates decoupling in multilayer PCBs.


  • Analog and digital portions of the circuit must be separated from the ground planes and they must be connected at a single point


  • It is recommended to avoid 90 degree trances because of EMI issues.


  • Better to avoid long tracks for the traces containing both analog and digital signals. Noise coupling can be avoided if both signals cross at one point.



Bow and Twist in multilayer PCBs is typically the result of unconventional designs.


Bow and twist is more likely to occur in asymmetric designs which can result in unbalanced stress conditions. For example, odd layer counts (3, 5 layer) are known to cause issues. Another source of multilayer PCB bow and twist comes from designs which specify variable layer thicknesses. For example, a 4 layer build specification of 7 / 28 / 21 creates more risk of deformation than a standard build. Even different circuit configurations can be influencing factors.



Multilayer PCB Thickness Parameters


Standard Multilayer Builds Mils per Dielectric Layer Resulting Thickness
  4 Layer 14 / 28 / 14 62 mil
  6 Layer 7 / 14 / 14 / 14 / 7 62 mil
  8 Layer 7 / 5 / 11 / 5 / 11 / 5 / 7 62 mil
  10 Layer 4 / 5 / 7 / 5 / 7 / 5 / 7 / 5 / 4 62 mil


So how can understanding more about the PCB multilayer assembly process help you reduce your PCB costs?


Ensure the specifications you are requesting are truly needed. While deviations from standard [tried and true" recipes are often possible, each subtle change carries additional risk, usually reflected in higher pricing, slower delivery times and occasional failure which could require a re-design. Additionally, we strongly recommend electrical testing for most multilayer printed circuit boards. Today`s software has helped designers provide consistently more manufacturable PCBs and you should expect even better results when you infuse your designs with the considerations provided above.



Multilayer PCB Disadvantages


The benefits of multilayer PCBs are numerous, making them applicable to a wide variety of advanced technologies. However, these types of PCBs aren't appropriate for all applications. In fact, several drawbacks can outweigh multilayer PCB advantages, especially for electronics of lower cost and complexity. These disadvantages include the following:

  • Higher Cost: Multilayer PCBs are significantly more expensive than single and double layer PCBs at every stage of the manufacturing process. They are difficult to design, taking an extensive amount of time to work out any potential problems. They also require a highly complex manufacturing process to produce, which takes a great deal of time and labor on the part of assembly personnel. Additionally, due to the nature of these PCBs, any mistake in the manufacturing or assembly process is prohibitively difficult to rework, resulting in either additional labor costs or scrap material expenses. On top of it all, the equipment used to produce multilayer PCBs is quite expensive because it is still a relatively new technology. For all those reasons, unless small size is an absolute necessity for the application, cheaper alternatives may be a better choice overall.

  • Complicated Production: Multilayer PCBs are more difficult to produce, requiring much more design time and careful manufacturing techniques than other PCB types. This is because even small flaws in the PCB's design or manufacture could render it useless.

  • Limited Availability: One of the largest issues with multilayer PCBs is the expenses of the machinery needed to produce them. Not all PCB manufacturers have the funds or the necessity for this machinery, so not all PCB manufacturers carry it. This limits the number of PCB manufacturers available to produce multilayer PCBs for clients. Thus, it's best to carefully inquire a PCB manufacturer's capability in terms of multilayer PCBs prior to deciding it as your contract manufacturer.

  • Skilled Designer Required: As previously discussed, multilayer PCBs require extensive design beforehand. Without previous experience, this can be problematic. Multilayer boards require interconnection between layers, but must simultaneously mitigate crosstalk and impedance issues. A single problem in the design can result in a non-functioning board.

  • Production Time: With increased complexity comes more manufacturing requirements. This plays into a key issue with multilayer PCBs' turnover rate – each board requires a significant amount of time to produce, resulting in more labor costs. Additionally, it possibly leads to longer periods between when an order is placed and when the product is received, which can be a problem in some circumstances.

However, these issues do not diminish from the utility of multilayer PCBs. While they tend to cost more than a single layer PCB, a multilayer PCB claims many advantages over this type of Printed Circuit Board.



Multilayer PCB Benefits


From a technical point of view, multilayer PCBs present several advantages in design. These benefits multilayer PCBs present include:

  • Small Size: One of the most prominent and lauded benefits of using multilayer PCBs lies in their size. Because of their layered design, multilayer PCBs are inherently smaller than other PCBs with similar functionality. This presents a major benefit to modern electronics, as the current trend is working toward smaller, more compact yet more powerful gadgets like smartphones, laptops, tablets and wearables.

  • Lightweight Construction: With smaller PCBs comes less weight, especially as the multiple connectors required to interlink separate single and double-layered PCBs are eliminated in favor of a multilayered design. This, again, is beneficial for modern electronics, which are geared more toward mobility.

  • High-Quality: Due to the amount of work and planning that must go into the creation of multilayer PCBs, these types of PCBs tend to be better in quality than single and double-layer PCBs. They also tend to be more reliable as a result.

  • Increased Durability: Multilayer PCBs tend to be durable by their nature. Not only do these multilayer PCBs have to withstand their own weight, but they must also be able to handle the heat and pressure used to bind them together. On top of these factors, multilayer PCBs use multiple layers of insulation between circuit layers, binding it all together with prepreg bonding agent and protective materials.

  • Enhanced Flexibility: Though this does not apply to all multilayer PCB assemblies, some do use flexible construction techniques, resulting in a flexible multilayer PCB. This can be a highly desirable trait for applications where mild bending and flexing may occur on a semi-regular basis. Again, this does not apply to all multilayer PCBs, and the more layers incorporated into a Flexible PCB , the less flexible the PCB becomes.

  • More Powerful: Multilayer PCBs are extremely high-density assemblies, incorporating multiple layers into a single PCB. These close-quarters enable boards to be more connective, and their innate electrical properties allow them to achieve greater capacity and speed despite their smaller size.

  • Single Connection Point: Multilayer PCBs are designed to work as a singular unit, rather than in tandem with other PCB components. As a result, they have a single connection point, rather than the multiple connection points required to use multiple single layer PCBs. This proves to be a benefit in electronic product design as well since they only need to include a single connection point in the final product. This is particularly beneficial for small electronics and gadgets designed to minimize size and weight.

These benefits make multilayer PCBs highly useful in a variety of applications, particularly mobile devices and high-functioning electronics. In turn, with so many industries turning to mobile solutions, multilayer PCBs are finding a place in an increasing number of industry-specific applications.



Advantages of Multilayer PCBs over Single Layer Alternatives


When compared to single layer alternatives, the advantages of multilayer PCBs become even more pronounced. Some of the key improvements multilayer PCBs offer include the following:

  • Higher Assembly Density: While single layer PCBs' density is limited by their surface area, multilayer PCBs multiply their density through layering. This increased density allows greater functionality, improving capacity and speed despite the smaller PCB size.

  • Smaller Size: Overall, multilayer PCBs are smaller in size than single layer PCBs. While single layer PCBs must increase the surface area of the circuit by increasing size, multilayer PCBs increase surface area through the addition of layers, decreasing overall size. This allows for higher-capacity multilayer PCBs to be used in smaller devices, while high-capacity single layer PCBs must be installed into larger products.

  • Lighter Weight: The integration of components in a multilayer PCB means less of a need for connectors and other components, resulting in a lightweight solution for complex electrical applications. Multilayer PCBs can accomplish the same amount of work as multiple single-layer PCBs, but does so at a smaller size and with fewer connecting components, reducing weight. This is an essential consideration for smaller electronics where weight is a concern.

  • Enhanced Design Functionality: Overall, multilayer PCBs are capable of being more than the average single layer PCB. With more incorporation of controlled impedance features, greater EMI shielding and overall improved design quality, multilayer PCBs can accomplish more despite their smaller size and lesser weight.

So, what do these factors mean when deciding between a multilayer and single layer construction? Essentially, if you're looking to produce a small, lightweight and complex device where quality is essential, a multilayer PCB is likely your best choice. However, if size and weight are not primary factors in your product design, then a single or Double Layer PCB design may be more cost-effective.



Multilayer PCB Applications


The advantages and comparisons discussed above beg the question: what's the use of multilayer PCBs in real world? The answer is just about any use.

For numerous industries, multilayer PCBs have become the preferred option for a variety of applications. Much of this preference derives from the continuous push across all technology toward mobility and functionality. Multilayer PCBs are the logical step in this progression, achieving greater functionality while reducing size. As such, they've become fairly ubiquitous, used in many technologies including:

  • Consumer Electronics: Consumer electronics is a broad term used to cover a wide range of products used by the general public. This tends to include products used on a daily basis, such as smartphones and microwaves. Each of these consumer electronics contains a PCB, but an increasing proportion of them are using multilayer PCBs instead of standard single layers. Why? Most of the reason lies in consumer trends. People in the modern world tend to prefer multi-function gadgets and smart devices that integrate with the rest of their lives. From universal remotes to smartwatches, these types of devices are fairly common in the modern world. They also tend to use multilayer PCBs for their increased functionality and smaller size.

  • Computer Electronics: Everything from servers to motherboards uses multilayer PCBs, primarily for their space-saving attributes and high functionality. With these applications, performance is one of the most essential characteristics of a PCB, whereas cost is relatively low on the list of priorities. As such, multilayer PCBs are an ideal solution for many technologies in this industry.

  • Telecommunications: Telecommunication devices often use multilayer PCBs in numerous general applications, such as signal transmission, GPS and satellite applications. The reason for this lies primarily in their durability and functionality. PCBs for telecommunications applications are often either used in mobile devices or towers outdoors. In such applications, durability is essential while still maintaining a high level of functionality.

  • Industrial: Multilayer PCBs do prove more durable than several other options currently on the market, making them a good choice for applications where rough handling may be a daily occurrence. As such, multilayer PCBs have become popular in several industrial applications, most notable of which are industrial controls. From industrial computers to control systems, multilayer PCBs are used throughout manufacturing and industrial applications to run machinery, favored for their durability as well as their small size and functionality.


  •  Medical Devices: Electronics is becoming an increasingly essential part of the healthcare industry, functioning in every corner of the industry from treatment to diagnosis. Multilayer PCBs are particularly favored in Medical industry for their small size, lightweight nature and impressive functionality compared to single-layer alternatives. These benefits have led to multilayer PCBs being used in modern X-ray equipment, heart monitors, CAT scan equipment and medical testing devices etc.

  • Military and Defense: Favored for their durability, functionality and low weight, multilayer PCBs are useful in high-speed circuits, which is becoming an increasing priority for military applications. They're also favored due to the defense industry's increased movement toward highly compact engineering designs, as the small size of multilayer PCBs leaves more room for other components to flourish existing functions.

  • Automotive: Cars are relying on electronic components more and more in the modern era, especially with the rise of electric cars. With everything from GPS's and onboard computers to headlight switches and engine sensors controlled by electronics, using the right kinds of components becomes increasingly essential in automotive design. This's why many auto manufacturers start to favor multilayer PCBs over other alternatives. While they are small and durable, multilayer PCBs are also highly functional and relatively heat-resistant, making them a good fit for the internal environment of an automobile.

  • Aerospace: Like cars, jets and rockets rely heavily on electronics in the modern era, all of which must be extremely precise. From the computers used on the ground to those used in the cockpit, aerospace PCB applications must be reliable, able to handle the stresses of atmospheric journeys while simultaneously making enough room for the rest of the surrounding equipment. Multilayer PCBs present an ideal solution in this case, with plenty of protective layers to keep heat and outside stress from damaging the connections, as well as the ability to be made from flexible materials. Their higher quality and functionality also contributes to this utility in the aerospace industry, as aerospace companies prefer to use the best materials possible to keep their personnel and equipment safe.

  • And Many More! Multilayer PCBs are used in a wide variety of other industries, including the science and research industry and even home appliances and security. Everything from alarm systems and fiber optic sensors to atomic accelerators and weather analysis equipment uses multilayer PCBs, taking advantage of the space and weight savings offered by this PCB format, as well as their heightened functionality.



Why Are Multilayer PCBs So Widely Used?


The specific applications listed above represent only a fraction of multilayer PCBs applied throughout the industry. But why are they used so widely?

Much of the favoritism toward multilayer PCBs lies in industry trends. With electronics progressing ever toward miniaturization yet multi-functional options, the internal components of those electronics must follow the same trend. While single and double-sided PCBs have proven limited in their ability to balance size and functionality, multilayer PCBs provide a comprehensive solution.

While there are several drawbacks to using multilayer PCBs over single and double-layer options, such as increased costs, design times and production inputs, these costs are becoming more accepted in today's world. Functionality is largely favored over cost, and people are willing to pay more for high capacity electronics. Additionally, as the technology becomes increasingly mainstream, production techniques and machinery will eventually become less expensive, especially as new techniques arrive in the industry.

With those irreversible trends and continuing progress of technology, many expect to see multilayer PCBs become even more abundant in the future.
