FPC flexible ribbon cables, also known as flexible circuit boards or flexible boards, are a type of printed circuit board with high reliability and excellent flexibility. It has the characteristics of high wiring density, light weight, and thin thickness. FPC flexible cables have a wide range of applications in electronic products, such as printers, mobile phones, laptops, etc. FPC flexible cables can be divided into various types according to their functions, such as FPC antennas, FPC touch screens, FPC capacitive screens, etc. FPC flexible ribbon cables are usually composed of a long strip of substrate, with both ends designed as plug-in needle shaped, which can be directly connected to connectors or welded to products. The substrate is generally made of rolled copper, which has excellent resistance to bending and flexibility. The welding process of FPC flexible cables is crucial in the manufacturing process. The welding points need to be firm, and the solder pads need to be filled with enough tin, but not too much, to prevent poor welding or overflow. At the same time, for multi-layer complex FPC soft boards, AOI detection equipment is also needed to scan and inspect the ribbon cables to ensure their quality and reliability. In addition, special attention should be paid to the storage and transportation of FPC flexible cables to avoid damage or contamination. When packing, it is necessary to wrap a layer of bubble film around the edge of the box and add moisture-proof beads to prevent moisture. Overall, FPC flexible cables are an important electronic component with broad application prospects and market demand. With the continuous upgrading and development of electronic products, the technology of FPC flexible cables will also continue to advance and improve.
