PCB – You Know Why Advanced Products Are So Powerful

Modern PCB's size, capability, and complexity are very unlike their ancestors. Did you know they have shrunk significantly and can now perform tasks that were unthinkable 30-40 years ago? Not long ago, things like HDI and micro-through holes were found only in expensive technical designs. But are now found in common devices that are readily available for the average consumer. Can the consumer demand for advanced products be directly related to the continuously high demand for PCBs? Let's find out!

 

1、Uses of PCBs

 

The continuing demand for PCBs stems from their many uses. They exist in almost every electronic device you own. However, it is the advancement of certain technologies and gadgets that keep the printed circuit board in high demand. For example:

- Wireless headphones are incredibly useful for those who live an active lifestyle or want to be free of that long cable hanging from your ears.

Smart Watches are made possible thanks to advancements in PCBs' size and are also a commodity.

- SmartPhones are not a new gadget, but every year, there is a better, more sophisticated model that will release, and this is thanks to improving PCBs.

- Smart technology is making huge steps in the technology world. You have voice-controlled speakers, smart TVs connected to your Wi-Fi. You have smart thermostats and electric meters at home to help you save on your household bills.

These are not all the devices that influence the high demand for PCBs. As mentioned above, they are in all-out electronic gadgets. However, it is the constant demand for high-quality, more sophisticated, and better-designed gadgets that will continue to keep the demand for PCBs in such a high number.

2、The Evolution of Technology and the Role of PCB’s

 

We see that everything is the beginning of an era of digitization, where comfort relies on electronics, where voice-operated gadgets are the norm. And this will only keep evolving. Society is demanding more and more gadgets designed to make our life easier. It could not have been made possible without the constant improvement of printed circuit boards. Their role is changing and becoming more important as society's need for creature comforts and easier life becomes apparent.

There is always room for improvement, even though PCBs of today are already incredibly complex. Different accessories attached directly to the board or the shape of the PCB itself are already in demand from consumers. These consumers are always pushing the limits for new PCBs and new functions. And they are getting new PCB functions.

A demonstration video can be seen here:

 

PCB Board Cameras

 

PCB Board Cameras, also known as Board Cameras, are cameras attached directly to a PCB. They are simple cameras composed of a lens, aperture, and an image sensor, designed to take digital photos and videos. Because of their size, it means you can place the camera on any electronic device. See your smartphone next to you? That is a clear example. But they are developing at such a high rate that these cameras will soon have many more uses beyond just a simple smartphone. Their use in medical instruments for non-invasive and minimally invasive procedures is growing. Did you know that there is a pill-sized camera you can swallow so a doctor can get high-quality, high-resolution images of your digestive tract? And they can only get better.

Surveillance technology is also benefiting from board cameras. Because of their size, they can hide in more objects than ever before. And as their quality improves, so will their uses in the surveillance industry.

 

3D Printing

 

3D Printing has been one of the biggest technological inventions of the last decade. It was something we thought unattainable until recently. And of course, since the first 3D printer, they have been improving. You can now buy smaller printers that fit comfortably at home, cheaper, and eco-friendlier. As they continue to improve with novel designs, improved efficiency, and friendlier to the environment, PCBs will change with them. Thanks to 3D printers, there is now such a thing known as 3D-PE, 3D Printed Electronics. It is creating electronic components layer by layer with a 3D printer and adding ink on top that contains the electric functionalities. It can change the way of manufacturing a circuit board, as they can make to any shape and size you can imagine.

3、Market Analysis

 

PCBs' future is looking very promising and will continue to be in high demand for years to come. It is estimated that by 2023, the market will reach an estimated $80.1 billion and have a CAGR of 3.3% from 2018 until 2023.

Emerging trends with a direct impact on the PCB industry include the miniaturization of PCBs, growing demand for high-speed data and phone signal, and the development of eco-friendly PCBs. It is forecasted that the standard multilayers will stay as the largest substrate type, thanks to increasing demand in the computer and communication industries. Meanwhile, the rigid-flex substrate is projected the highest growth because of a growing demand for smartphones and display applications.

Throughout the forecasted period inside the PCB market, the computer industry will continue to be the largest. It is because of the increasing demand for computers in healthcare, education, and business sectors. Because of the demand for connected devices, the consumer electronics sector is expected to see the largest growth.

 

4、The Future of PCBs

The future of PCBs beyond their uses in a constantly growing consumer electronic market lies in their production. Flexible and Biodegradable PCBs are the future for these boards.

Flexible PCBs are estimated to grow faster than standard boards, reaching $15.2 billion by 2020, and $27 billion by 2022. It is due, in most part, to flexible displays and medical applications.

These types of PCBs can handle more stress and bending. Thus, being folded into awkward spaces and making them excellent for applications where frequent bending is involved. They are also lightweight and easy to mass-manufacture. Their applications include:

- LED lighting, which because it is bright and eco-friendly, is incredibly popular. LED strips need flexible PCBs to operate but maintain the ability to bend to suit consumers' needs.

- Wearable technology is also becoming reliant on flexible PCBs, with smart socks, wristbands, and belts needing to bend to fit the wearer. Flexible PCBs can handle the bending of these products and the vibrations and shock factors, too, as most wearable technology is to help in sports.

- Flexible displays are yet to explode in a big way due to their manufacturing costs. However, once reduced costs with flexible PCB help, they will be the next important factor.

Potentially leading to flexible smartphones and tablets because of their ability to withstand shock and impact better than rigid displays.

- Medical instruments are now focusing on minimalization and flexibility. And with the help of flexible PCBs, they can achieve both.

If these trends continue, you can expect to see a high rise in flexible PCBs' demand.

Biodegradable PCBs

Biodegradable PCBs is the industry's way of dealing with the major concern of e-waste, or electronic waste. Electronic scrapping is becoming more and more popular, but this waste still exists and is a problem that needs to be solved. Components of standard printed circuit boards do not degrade well and cause much of the problem. Furthermore, the chemicals used during the manufacturing process are harmful to the environment if not disposed of properly.

There are many suggestions on helping this problem, from proper e-waste collections to extracting certain metals used, such as palladium, gold, and silver from old electronics, smelting them, and reusing them. One serious consideration is the use of environment-friendly alternatives during the manufacturing process. Currently studying biodegradable substrates and alternatives to hazardous chemicals.

 

5、Conclusion

 

From what we can see above, PCBs are still in very high demand and will continue to be so. Because of consumer electronics' future and the continued improvement of PCBs, the market will always be developing new technologies that will keep the demand high. Flexible and Biodegradable PCBs are becoming more and more popular, and with good reason too. They are becoming a necessity in many sectors worldwide.
