How Do Wave Soldering Machines Work?

Wave soldering is a large-scale soldering process that uses waves of molten solder to secure components to the PCB. It is used primarily in Through-Hole PCB assembly, because it completely coats one side of the board. With Surface Mount Technology, both sides of the board often contain components that could be damaged if subjected directly to a solder wave. For these types of boards we generally use selective soldering.


A wave solder machine goes through 3 separate processes:

  1. First, the machine applies a layer of flux to the underside of the entire board. This removes any impurities from the board and prevents the metal from oxidizing while heated for soldering. Oxide layers can affect the soldering process and lead to poor quality of solder joints.

  2. After the flux has been applied, the PCB is placed on a preheating pad both to activate the flux before soldering and to help prevent the board from suffering thermal shock.

  3. Lastly, the PCB is passed over a molten “wave” of solder via a conveyor system. As the PCB passes over the wave of solder, a connection is made between the electronic component leads, the PCB pads/holes, and the solder itself, forming an electrical connection.

Precision Wave Soldering from the Experts at Telan

It takes skill and training to operate a wave soldering machine properly. If the wave height is not set correctly it could lead to solder skips and missing connections. If the solder temperature is too high, it can create solder balling. At Telan, our experienced staff can produce your boards with quality, reliable solder joints.
