What are the Manufacturing Technologies for Flexible Copper Clad Laminates
Whatever it is a 3 layer flexible copper clad laminate or 2 layer flexible copper clad laminate, there are three main manufacturing technologies. Each FCCL manufacturer will adopt different technologies according to its own characteristics. Do you know what manufacturing technologies are used in flexible copper clad laminates? 1. Coating Method The coating method is a copper foil coated with adhesive, uniformly coated the prepolymer of liquid polyimide resin , such as the copper foil of the 2 layer flexible copper clad laminate without an adhesive layer, and then pass it through the adhesive layer , and then through heating and drying, the coating resin is imidized t o form a polyimide resin film. For 2 layer flexible copper clad laminates, generally in order to improve the higher adhesion between the resin layer and the copper foil, some technologies first coat a layer of high-adhesion polyimid...
