Flexible PCB

The common flexible PCB packing is to stack the flexible PCB of 10 ~ 20pcs together, and fix in a cardboard with paper rolls to avoid using tapes, because tape adhesives which contain chemical substances, if be exudative it will easily lead to discolor the terminal oxidation. When the basement membrane is a polyimide film as it can easily absorb moisture, flexible printed circuit boards should be loaded together with silica gel and desiccant into the polyethylene bags and pressurize the bags. And then cased into corrugated boxes with cushioning materials. Due to the unique shape of the flexible PCB, different form should be used different packings.
