Wave soldering is the classic soldering process for manufacturing electronic modules that are predominantly assembled with through-hole components. The soldering contact inserted through the PCB and the soldering on the bottom of the PCB are characteristic of this soldering process.

All mounting and soldering processes at a glance
Example illustration of surface mount technology

Surface mount technology (SMT) is used for surface mounting components. The components are assembled in soldering paste on the surface of the PCB and soldered in the reflow soldering process. This method requires special components with corresponding surface contacts.
