Occasionally VMI receives a customer inquiry regarding recommended soldering practices for our axial-leaded diodes.
Methods for Soldering High Voltage Diodes
Normally an axial-leaded diode would be hand soldered, but there are instances where it could be wave-soldered. Wave-soldering does not typically require a thermal shunt or heat sink.
When hand soldering, VMI recommends using a soldering iron with a 600 degree F tip for most tin/lead solders, and a 700 degree F tip for lead-free solders such as Sn96.

Although other factors can impact the soldering process such as the size of the connection, lead thickness & material, the type of parts being joined, the typical dwell sime should be completed within three seconds.
This same soldering practices can apply to VMI's high voltage rectifiers such as the SPJ high voltage stacks, SP high voltage stacks, and the high current, high voltage FP rectifier stacks.
