What is FPC? I don't think many people know this question yet! What is FPC, then let me explain it to you! FPC, that is, flexible printed circuit board, the Chinese name is flexible printed circuit board. It is a circuit board with flexible characteristics made of polyester film or polyimide film as the base material through chemical etching, photopainting, copper pouring, electroplating and other processes.
Everyone knows that the traditional circuit board is hard, that is, we commonly call the hard circuit board, but this kind of hard circuit board also has its shortcomings. I believe that everyone has such troubles, he can't bend, and when I have the need to bend, he can't meet our needs, so it also brings us a little inconvenience. This is where FPC (Flexible Circuit Board) comes in, which has many advantages over traditional rigid circuit boards.
First of all, FPC has good flexibility. FPC can be bent, folded, rotated and curled, etc., with good plasticity, suitable for use in curved, curved and irregularly shaped electronic products. Such characteristics make FPC can be applied in electronic devices of different shapes and sizes, such as smart bracelets, smart watches, smart glasses, etc.
Secondly, FPC has the characteristics of thinness. FPC uses polyester film or polyimide film as the base material, making it thinner than conventional circuit boards. This is important for many electronic products that pursue thin and light design and miniaturization. Such as smartphones, tablets, etc.
In addition, FPC is also characterized by light weight, flexible layout, and high reliability. Due to the flexible substrate used in FPC, it is relatively lightweight, which is advantageous in some applications where weight is critical. In addition, FPC can be freely laid out and designed according to the actual needs of electronic products, so as to meet the needs of different application scenarios. At the same time, FPC's flexible substrate has good tensile strength and heat resistance, can work in a wide range of temperatures, and also has good oxidation, corrosion and anti-photoaging characteristics, so that the reliability of FPC is also guaranteed.
FPC has many advantages as a new type of circuit board. The emergence of FPC will make the design of electronic devices more flexible, and will also help promote the development of lightweight, miniaturization and flexibility of electronic devices. At present, FPC has been widely used in mobile communications, smart wearables, medical equipment, industrial automation and other fields, and more application scenarios will emerge in the future.
