Soldering

Soldering of the relays by hand as well as in common wave soldering machines is possible. The maximum temperature and soldering time specified in the corresponding data sheet must not be exceeded. In wave soldering systems, we recommend preheating at a maximum of 130 °C. The time should be selected so that the relay just reaches this temperature. The time should be chosen so that the relay just reaches this temperature. A possible soldering profile is listed in the standard DIN EN 61810-1, Annex N. If a flux is used, it must not be aggressive or acidic. Also, only the underside of the PCB should be wetted.
