FPC is the abbreviation of Flexible Printed Circuit. Also known as flexible circuit board, flexible printed circuit board, flexible circuit board, or touch screen FPC for short. It has the characteristics of high wiring density, light weight and thin thickness.
Mainly used in many products such as mobile phones, laptops, PDAs, digital cameras, LCMs, etc.
FPC flexible printed circuit is a highly reliable and excellent flexible printed circuit made of polyimide or polyester film as the base material.

Flexible copper clad laminates (FPC) with flexible functions and epoxy resin as the base material are becoming more and more widely used due to their special functions, and are becoming an important variety of epoxy resin-based copper clad laminates. But our country started late and has yet to catch up.
Epoxy flexible printed circuit boards have experienced more than 30 years of development since their industrial production. From the 1970s to the real industrial mass production, until the late 1980s, due to the advent and application of a new type of polyimide film material, flexible printed circuit boards made the FPC a non-adhesive type. FPC (generally referred to as “two-layer FPC”).
In the 1990s, a photosensitive cover film corresponding to high-density circuits was developed in the world, which caused a great change in the design of FPC. Due to the development of new application areas, the concept of its product form has undergone a lot of changes, and it has been expanded to include a larger range of substrates for TAB and COB. The high-density FPC that emerged in the second half of the 1990s began to enter large-scale industrial production. Its circuit patterns are rapidly developing to a more subtle degree, and the market demand for high-density FPC is also growing rapidly.
The main function of FPC to the touch screen is to connect the touch screen to the main board, and then it also plays a role in transmitting current and signals. It is also very important for touch screens. Because there is no FPC, there is no way to connect the touch screen to the motherboard. The touch screen cannot work.
Because FPC is a relatively fragile part. In particular, some small-sized touch screens will make chips and other components directly on the FPC. So you have to be extra careful when inserting the FPC to the motherboard. Because it is easy to damage the touch screen channel.
