1、 What is FPC connector
The abbreviation for flexible printed circuit connector in the market is FPC connector. They have the characteristics of high cable density, lightweight, and thinness, hence they are called soft circuit boards, soft printed circuit boards, or flexible circuit boards. Most FPC connectors are manufactured using polyimide (PI) or polyester film (PET) as raw materials, which improves the reliability of FPC connectors. FPC connectors are used for connecting LCD displays to driver circuits (PCBs), mainly for 0.5mm pitch products.

2、 The structural composition of FPC connector products:

FPC connectors can achieve thinning and seek miniaturization to reduce the footprint of connectors. They are connectors for high-frequency signal transmission and consist of four parts: rubber core, tongue, terminal, and solder joint. The following is a knowledge explanation of these four parts;

1. The function of FPC connector core is to protect terminals, insulate them, ensure proper conductivity during connection, and provide structural strength. The manufacturing process of FPC connector core generally uses injection molding technology, and the material is mostly PA9T material.

2. The function of FPC connector tongue is to crimp and connect wires, provide insulation, ensure proper alignment during connection, and provide structural strength. The manufacturing process of FPC connector tongue is generally carried out using injection molding technology, with materials such as PA10T and PPS.

3. The function of FPC connector terminals is to transmit electronic signals as conductors. The manufacturing process uses stamping electroplating technology (gold or tin plating to enhance the product's soldering ability), and the material used is phosphor bronze C5191 material.

4. The function of FPC connector solder pads is to locate, fix, and increase strength of components. The manufacturing process also uses stamping electroplating technology (gold or tin plating to enhance the product's soldering ability), and the material used is bronze C2680 material.

3、 FPC Usage

FPC connectors come in various types, are compact and miniaturized, save space, and have high-density integration. They have simple wiring procedures and connections, excellent flexibility, and can be folded and extended flexibly. Therefore, their application fields are also quite extensive.

FPC connectors are mainly used for:

1. Electronic devices such as LCD displays, scanners, etc.

2. Computer motherboard, LCD display, telecommunications card, memory, portable hard drive, including mobile devices. Mobile devices such as smartphones, MP3 players, and laptops are increasingly using impact resistant back lock mechanism connectors when using FPC connectors.

3. Automotive electronic connectors, car GPS navigation, medical equipment, products are widely used in audio systems, digital machines, cameras, car audio systems, televisions, typewriters, calculators, cash registers, telephones, CD ROMs, VCDs, DVDs, copiers, printers, wireless instruments and meters, video calling equipment, and high-tech equipment for aerospace products.
