The most common packing method of FPC is to pile up 10~20pcs flexible printed circuit boards (FPC) together, fix every part on the rigid board by using paper strips. We should avoid using tape, because if the chemical substances in the tape adhesives oozes, the terminal would be easy to be oxidized and change color. The base material is polyimide which is easy to absorb moisture. The flexible printed circuit boards together with silica gel, etc. the drying agents have to be put into the polythene bag and sealed. Then put it into the cartons together with cushion material. Due to special shapes of FPC, we should adopt different packing methods according to different shapes.
Before punching the outline of flexible printed circuit boards, firstly stick the FPC on the polyester supporting spring printed with adhesives, using knife mold to cut the outline, and then send to our clients. The clients can get the flexible printed circuit boards and do the assembly, or they can do the assembly at first, take them from the polyester supporting spring after finishing the assembly. This method can be only applied on the products with small dimensions. Which can greatly improve the operation efficiency whatever to flexible printed circuit boards manufacturers or to clients.
The safest way is to use special tray, at first we prepare the trays according to the FPC types. Although the management is complex, the quality is guaranteed. They are convenient to use and helpful for client assembly, low cost and can be thrown away thereafter.
