Wave soldering remains one of the most proven and at the same time highly advanced interconnection technologies in electronics manufacturing.
Despite increasing miniaturization and the growing dominance of reflow processes, it remains indispensable in many areas – especially for THT assemblies, power modules, and hybrid designs that demand maximum robustness and process stability.
How Wave Soldering Works
In wave soldering, the populated PCB is guided across a standing wave of molten solder. This solder wave selectively wets component leads and pads, creating strong, reliable solder joints.
The process consists of four key stages:
Flux Application – The flux removes oxides and ensures optimal wetting.
Preheating – The assembly is gradually heated to minimize thermal stress.
Solder Wave – A precisely controlled solder wave provides uniform wetting of all connections.
Cooling – The solder joints are cooled in a controlled manner to ensure mechanical stability.
The result: homogeneous, shiny, and highly reliable solder joints – consistent and repeatable.
