In the application of FPC connector products, contact performance is one of the most important parts, but during the use of FPC connector, its contacts may be affected by some factors, which may lead to some failures, which usually lead to FPC The main problems of connector contact performance damage are as follows:

1. Contact corrosion problem of FPC connector

FPC connectors need to be customized and used according to the different environments of the application industry. In some harsh working environments, FPC connectors may be affected by some special organic gases to corrode their contacts. Corrosion and pollution will increase the resistance of the contacts. , Thereby affecting the electrical performance of the FPC connector.

2. Arc corrosion problem of FPC connector

When the conductor is closed under high voltage and high current intensity, arc discharge will occur. The arc discharge will generate instantaneous high temperature. The high temperature will melt and vaporize the metal surface of the FPC connector contact and cause the FPC connector contact to deform. When the arc discharge forms a plasma state, the metal surface of the FPC connector contact will be covered with a chemical film. This uncontrollable chemical film is the main factor affecting the electrical performance of the FPC connector.

3. Vibration problem of FPC connector

FPC connectors often encounter vibration problems in practical applications. These vibrations cannot be detected by the naked eye, and the amplitude is usually in the micron level. There are many reasons for the vibration of the FPC connector, which will cause the contacts of the FPC connector to be worn and deformed, and ultimately increase the resistance between the contacts.
