Description

FPC fixing jig capable of being turned over on two sides Technical Field The utility model relates to the technical field of circuit boards, in particular to an FPC fixing jig capable of being turned over on two sides. Background FPCs are all known as "flexible circuit boards" and are printed circuits made from flexible, insulating substrates. The FPC provides excellent electrical performance, can meet the design requirement of smaller and higher-density installation, is also beneficial to reducing assembly procedures and enhancing reliability, is the only solution for meeting the miniaturization and movement requirements of electronic products, can be freely bent, rolled and folded, can bear millions of dynamic bending without damaging wires, can be randomly arranged according to the space layout requirement, and can be randomly moved and stretched in a three-dimensional space, thereby achieving the integration of component assembly and wire connection, greatly reduces the volume and weight of the electronic products, and is suitable for the requirement of developing the electronic products to high-density, miniaturized and high-reliability directions. In the production and processing process, after the FPC is unfolded and fixed by utilizing the fixing jig, the fixing jig and the FPC are further fixed in processing equipment for high-precision production, processing, testing and the like.
