What is selective soldering? Learn how selective soldering works, when it is used and its advantages over wave soldering.
What is Selective Soldering?
Selective soldering is a soldering process where individual THT solder joints are targeted using a mini solder wave or solder pot.
Selective soldering is a precision soldering process for through-hole (THT) components where — unlike wave soldering — only selected areas of the board are soldered. A programmable mini wave or solder pot is guided precisely to the THT solder joints.
Process and Application
The process is particularly advantageous for mixed-technology assemblies where SMD components are already present on the solder side. Only the desired joints are wetted with solder, without thermally stressing neighbouring components.
The selective soldering process runs fully automatically: the PCB is scanned, flux is applied via micro-nozzle, the assembly is locally preheated, and then the solder joints are soldered individually or in groups.
