Soldering, reed switches

Often, a reed switch has to be soldered or welded. Reed switches are usually plated with suitable solderable plating. Welding is also quite easy on the nickel/iron leads of the reed switch. However, both, if not carried out properly, can cause stress, cracking, chipping or a rupture in the reed switch. When soldering or welding, it is best to keep as far away from the glass seal as possible. This may,... [Pg.129]

Most commercial wave soldering machines have a preheating section before the PCB or assembly is immersed into the solder wave, the thermal shock is reduced As the ambient temperature has already been raised before the solder wave, the thermal gradient in the reed switch seal is reduced. [Pg.130]
