Little Knowledge About FPC Connectors

The function and application scope of FPC connector products

The function of the FPC connector product is to connect the circuit board (PCB) and the flexible printed circuit board (FPC) to realize the mechanical and electrical connection. Today's FPC connectors are mainly used in LCD and LED liquid crystal displays, scanners, digital cameras, game consoles, tablet computers, notebook computers, car theaters and other electronic equipment. FPC connector products are also widely used in audio, digital machines, cameras, car audio, televisions, typewriters, calculators, cash registers, telephones, CD-ROMs, VCDs, DVDs, copiers, printers, wireless instruments and other equipment.

Second, the structure of FPC connector products

FPC connector can be thinner, and in order to reduce the occupied area of the connector, and seek miniaturization, high-frequency signal transmission connector, this connector consists of four parts, namely, rubber core, tongue piece, terminal, and soldering piece. , The following is the knowledge explanation of these four parts;

1. The function of the FPC connector rubber core is to protect the terminals, insulate, guide the connection, provide mechanical strength, etc. The manufacturing process of the FPC connector rubber core generally uses an injection molding process, and the materials are mostly LCP, PA9T materials.

2. The function of the FPC connector tongue is to crimp the cable, insulate, guide the connection, provide the strength of the mechanism, etc. The manufacturing process of the FPC connector tongue is generally injection molding, and the material uses LCP. PA9T, PPS materials .

3. The function of the FPC connector terminal is the conductor transmission of electronic signals. The manufacturing process uses a stamping and electroplating process (gold or tin plating to improve the soldering ability of the product), and the material uses phosphor bronze C5191 C5210.

4. The function of the FPC connector welding piece is component positioning, fixing, increasing strength, etc. The manufacturing process also uses a stamping and electroplating process (gold or tin plating to improve the welding ability of the product), and the material uses bronze C2680.
