FPC applications MP3, MP4 players, portable CD players, home VCD, DVD, digital cameras, mobile phones and mobile phone batteries, medical, automotive and aerospace fields FPC has become an important variety of epoxy copper clad laminates. It has flexible functions and is epoxy resin. The flexible copper clad laminate (FPC) of the base material has become more and more widely used due to its special function, and it is becoming an important variety of epoxy resin-based copper clad laminate.
But our country started late and has to catch up. Epoxy flexible printed circuit boards have experienced more than 30 years of development since their industrial production. Since the beginning of the 1970s, it has entered the real industrialized mass production. Until the late 1980s, due to the advent and application of a new type of polyimide film material, the flexible printed circuit board made the FPC appear 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 major change in FPC design. Due to the development of new application areas, the concept of its product form has undergone a lot of changes, which has been extended to include TAB and COB substrates in a larger range.
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.FPC application field
