Users who often deal with FPC connectors, it is very necessary to understand the structure of some FPC connectors, so what is the structure of the FPC connector?

FPC connector can be thinned, and to reduce the footprint of the connector, and to achieve miniaturization, high-frequency signal transmission connector, the connector consists of four parts, respectively, the core, tongue, terminal, solder tab. The following are the knowledge explanation of the four parts;

1. The function of the FPC connector rubber core is to protect the terminal, insulation, guiding when connecting, providing the strength of the mechanism, etc. The manufacturing process of the FPC connector rubber core is generally using an injection molding process, and the material is mostly PA9T material.

2. The function of the FPC connector tongue is to crimp the cable, insulation, guiding when connecting, providing the strength of the mechanism, etc. The manufacturing process of the FPC connector tongue is generally using the injection molding process, the material is PA10T, PPS material.

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

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