PCB Wave Soldering Process

Dated:2017-12-03      Popularity:1279

Wave soldering is a batch soldering process used to make printed circuit boards. Wave soldering is used for through-hole printed circuit assembly and surface mounting.

In the process of wave soldering, the molten solder is transformed into the desired wave by mechanical bump or electromagnetic bump flowing that features jet flow. PCB board with assembled components must pass through the solder wave to allow mechanical and electrical soldering between component soldering points or PCB pad.

The main task is to pre-mold some components to make them meet the requirements of mounting, plugging and wave soldering.

The key steps in wave soldering process include component molding, component insertion or mounting, soldering and cooling by soldering waves. This means that molded components can be plugged on the PCB board as needed. Then PCB loaded with components is pushed into the wave soldering system by the transmission device. Next, solder flux is sprayed and PCB is preheated in the preheat zone. The final step comes with the wave soldering and cooling.
