FPC connector structure and principle
FPC is the abbreviation of flexible printed circuit board. Generally speaking, the connector is made of soft material (PCB which can be folded and bent). The connector is used for the connection of LCD display to drive circuit (PCB). The main product is 0.5mm pitch. The 0.3mm pitch FPC connector has also been used in large quantities.
With the trend of LCD drivers being integrated into LCD devices, the number of pins in FPCs has been reduced accordingly, and related products have appeared on the market. In the longer term, FPC connectors will be expected to be integrated with other mobile phone components on the frame of mobile phones or their LCD modules.
Products are mainly used in various digital communication products, portable electronic products, computer peripherals, measuring instruments, automotive electronics and other fields, such as mobile phones, digital cameras, notebook computers, MID, MP3\4\5, handheld game consoles, audio systems, etc.
FPC connector, contact 3mm printed circuit board mounting height flip lock (one-touch rotary system), prevent dropout and FPC assembly, elastic needle design, available in 0.3, 0.5, 1.0, and 1.25mm DIP, SMT, vertical and right angle assembly.
FPC connector features
The flipping of FPC connectors should be miniaturized. As many products face smaller and concise opening, the use of FPC connectors will become more sophisticated. For example, the most common line-to-board selection is 0.6mm and 0.8mm, high density, high speed transmission, high frequency direction opening. Miniaturization means that the distance of the fpc connector base is smaller, and the high density is to complete the large core number.
FPC connector structure principle
Users who often interact with FPC connectors, it is very necessary to understand the structure of some FPC connectors, then what is the structure of the FPC connector? The following small series will come to your FPC connector structure. The principle of this aspect.
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 is the knowledge of these 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.

Miniaturization means that the distance of the fpc connector base is smaller, and the high density is to complete the large core number.
The high-density FPC connector has a total of 600 cores for touch and up to 5,000 cores for special equipment.
High-speed transmission refers to the time-scale rate of modern computer, information skill and network technology request signal transmission to megahertz frequency band, the pulse time reaches sub-millisecond, so it is required to have high-speed transmission FPC connector. The high frequency is turned on for the habit of the millimeter wave, and the RF coaxial connectors have entered the millimeter wave operating band.
