Application of FPC flexible circuit board in intelligent hardware, medical, industrial control and other equipment

Flexible Printed Circuit (FPC), also known as flexible circuit board and flexible circuit board, is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film. With the characteristics of high wiring density, light weight, thin thickness, and free bending and folding, it is popular.



According to the data of authoritative organizations, the annual sales volume of global PCs has continued to rise, and has basically stabilized in recent years, reaching more than 160 million units.

There are many kinds of FPCs involved in the PC, as shown in the figure below, such as the camera module of the PC, the connection part of the capacitive screen, the key part, the optical drive head, the antenna and other parts, all have the figure of the FPC circuit board.



2 Medical products



According to the forward-looking industry research institute, the global medical device market size reached 425 billion US dollars in 2018 and nearly 446.3 billion US dollars in 2019.



From 2014 to 2018, the overall size of China's medical device market showed an annual growth trend. The scale of China's medical device market reached 530.4 billion yuan in 2018, and nearly 625.9 billion yuan in 2019.



Common FPC application scenarios in medical products include:



Gastroscope circuit board:



Traditional products are limited by the bending capacity and rigidity of the circuit board, and the catheter can not well cooperate with the operation of medical personnel. However, the gastroscope with FPC soft plate has better bending and bending performance, and has been verified by many years of application.



Medical device screen:



Most of the adapter cables on the screen of medical devices are FPC soft boards, not only on medical devices, but also on most display screens, which is a great affirmation of the bending and bending characteristics of the soft boards.



Medical device keys:



The use of FPC soft board on keys is also a large-scale model. The medical keys and other keys have a great test on the product sensitivity.



Rhythm regulator:



The research of FPC soft board in MEMS is very important. In the modern era of higher and higher medical level, the combination of electronic devices and human body is more and more common, such as heart and heart bridging, electronic prostheses, and so on.



B-ultrasonic head circuit board:



B-ultrasound is a perspective of the inside of the human body through the ultra-strong signal flow. The FPC soft board with electronic components can accurately transmit the signal and adjust the signal frequency to a level that people expect to achieve, thus realizing the transmission of signal and video.



Medical hearing aids:



This product appeared earlier, but in addition to the difference between the size and model of the ear, the traditional hearing aid still has defects in current transmission, and there is often noise in it. The hearing aid with FPC soft board has excellent performance in ear fitting, and is soft and durable.



Household portable medical electronic equipment:



At present, more and more medical devices are entering the home to meet the needs of convenient medical diagnosis. FPC soft board can well realize bending and miniaturization, providing convenience for this product.



3 Industrial control equipment



According to the 2018 Industrial Control Market Data released by CCID Consulting, the scale of China's industrial control market reached 179.7 billion yuan in 2018, up 8.5% year on year. It is expected that the average annual growth rate will be 12% in the next three years, and the market size is expected to reach 260 billion yuan in 2021.



FPC is widely used in industrial control equipment, such as display screen, intelligent keys, bendable mechanical parts, etc.



4 Electronic tool products



The application of FPC in tool products covers new electronic tools. The new portable electronic tools are quite different from traditional tools, and have more functions such as display, button, touch, deformation, etc. Among these tools with electronic functions, FPC is widely used with the characteristics of supporting miniaturization, thinness and flexibility.



Of course, the application of FPC is far more than these. In the era of rapid development of science and technology, it has almost spread in all aspects of our lives. In the future, more FPC products will appear in our lives. Products derived from smart home, the Internet of Things, smart medical, artificial intelligence and other industries will generally adopt FPC soft board as its core component, leading the market of miniaturized, thin and flexible products.
