In the application of FPC connector products, contact performance is one of the more critical components. However, during the use of FPC connectors, their contacts may be affected by certain factors, leading to various malfunctions. The primary reasons for the degradation of FPC connector contact performance are as follows:
Contact Corrosion Issue with FPC Connectors
FPC connectors must be customized for use in various environments of their respective application industries. In some harsh working conditions, FPC connectors may be affected by certain special organic gases, leading to corrosion of their contacts. Corrosion and contamination can increase the resistance of the contacts, thereby impacting the electrical performance of the FPC connectors.
2. Arc corrosion issue with FPC connectors
When a conductor closes under high voltage and high current intensity, an arc discharge occurs. This arc discharge generates an instantaneous high temperature, which melts and vaporizes the metal surface of the FPC connector contacts, leading to deformation of the FPC connector contacts. When the arc discharge forms a plasma state, a chemical film will cover the metal surface of the FPC connector contacts. This uncontrolled chemical film is a major factor affecting the electrical performance of the FPC connector.
3. Vibration Issue with FPC Connectors
FPC connectors often encounter vibration issues in practical applications, which are invisible to the naked eye and typically occur at a micron-level amplitude. There are numerous reasons for the vibration in FPC connectors, all of which can cause wear on the connector's contacts, lead to deformation, and increase resistance between the contacts.
