The connectors inside mobile phones mainly include FPC connectors, board to board connectors, wire to board connectors, and other types. The FPC connector is used as the connection line for the rear fingerprint recognition module, the connection line for the main and auxiliary boards, and the connection line for the mobile phone screen driver circuit (PCB). The performance of FPC connectors directly affects the use of mobile phones, so it is necessary to test the appearance, performance, and quality of FPC connectors. There is a high current spring clip micro needle module that can provide stable connections during FPC connector testing to ensure smooth testing.
The characteristics of FPC connectors are light weight, thin thickness, and high wiring density. It can be summarized into four points:
Lightweight: FPC connectors are soft boards that are lighter in weight than hard boards, which can reduce the weight of mobile phones
Thin: FPC connectors are thinner than PCBs, have higher flexibility, and can be assembled in limited space with three dimensions
Short: assembly time is short, all circuit configurations can be completed, saving more wiring work
Small: FPC connectors have the characteristic of small volume, which can effectively reduce the size of the product and make it easy to carry
When using FPC connectors, some precautions should be taken to effectively avoid risks and extend their service life.
1. Avoid using in damp environments, as damp environments can cause corrosion to the plastic film and internal metal components of FPC connectors, resulting in surface pin cores becoming damp.
2. Avoid using in environments with excessively high temperatures, as high temperatures can cause corrosion of the pin cores of FPC connectors, resulting in surface oxidation, loss of contact pressure, and even direct burning of the connectors.
3. Avoid using in harsh environments, especially those with strong corrosiveness, as it can cause deformation of the pins inside the FPC connector and corrode the pores and surface metal particles of the connector.
4. The insertion and extraction force of FPC connectors is very important. If the separation force is too strong, it will affect the reliability of pin core contact. Therefore, in the use of connectors, the insertion force should be large and the extraction force should be small.
5. Do not plug connectors randomly, as the lifespan of FPC connectors will decrease over time. Therefore, when not in use, be careful not to plug connectors randomly to avoid wear and reduce their lifespan.
FPC connector testing should be completed before assembly and shipment. The application of high current spring clip micro needle modules can improve efficiency and ensure the yield of mother seat testing. When transmitting current, the high current bullet micro needle module can pass a current of 1-50A, and the connection is stable without attenuation, with strong overcurrent capability; There are also good ways to deal with it in the small pitch. Within the range of 0.15mm-0.4mm, this module can maintain stable connections without getting stuck or stuck; When connecting the high current spring clip micro needle module to the male and female sockets, a serrated contact FPC connector male socket and a pointed contact female socket can be used, with a yield rate of up to 99.8%.
Above, the high current spring clip micro needle module has high compatibility with FPC connector testing, and its performance can well meet the needs of FPC connectors, achieving the goal of improving testing efficiency. (Shilian Electronic Pin Female Pin Female Connector)
