List the installation and storage methods of the relay

The transport mode of the relay needs to be careful. The relay should be stored and installed in a clean environment so that the relay can be well protected.

1. Solder flux

Non-plastic-encapsulated relays are extremely susceptible to contamination by flux. It is recommended to use flux-resistant or plastic-encapsulated relays to prevent the intrusion of flux gas from the terminal and the gap between the base and the housing. Such relays are suitable for multi-bubble fluxing or spraying flux processes. Anti-flux type relays can further prevent flux intrusion if they are preheated and dried.

2. Welding process

When using flux or automatic welding, care should be taken not to damage the performance of the relay. The flux-resistant relay or plastic-encapsulated relay can be suitable for dip soldering or wave soldering process, but the maximum welding temperature and time should be controlled according to the selected relay.

3. Cleaning process

Avoid the overall cleaning of the non-plastic relays. The plastic relays should be cleaned with appropriate cleaning agents. It is recommended to use freon or alcohol; ultrasonic cleaning should be avoided as much as possible because harmonics of the ultrasonic frequency will cause contact friction Soldering (cold soldering) and may cause the contacts to get stuck. After cleaning and drying, ventilation should be performed immediately to bring the relay to room temperature.
