Preparation method of flexible copper-clad plate

Номер: CN116512729A
Автор: YUAN QINGYU, LI XINHUA, YANG TONGCHAO
Принадлежит:

The invention relates to a preparation method of a flexible copper-clad plate, which comprises the following steps of: firstly, preparing an adhesive, coating the adhesive on a metal foil, baking and drying the adhesive on the surface, annealing and sending a plastic film for preheating, and then laminating the surface-dried metal foil with an adhesive layer and the annealed plastic film up and down to obtain the flexible copper-clad plate. And meanwhile, feeding into a pressing wheel for pressing, and automatically rolling and curing after pressing to obtain the flexible copper-clad plate. According to the method, the size stability of the flexible copper-clad plate prepared through the method is good, the problems of production wrinkles, abnormal appearance and the like caused by uneven tension of the plastic film can be solved, meanwhile, warping is improved, the process is simple, operation is convenient, the production efficiency can be improved, and the production requirement is met ...
