Wave soldering is mainly used for through-hole components, while Reflow Soldering is used for surface-mount components. So, are there any other differences between them? Shenzhen JJY, as a Solder paste manufacturer, will answer for partners:

Wave soldering uses molten Soldering solder wave peaks to solder the components. In contrast, reflow soldering takes place in the hot air of a high-temperature zone, where the solder is reflowed and melted, and only then can the components be soldered.

The working processes of wave soldering and reflow soldering are different.

Wave soldering: it is completed after Flux is applied, the board enters the preheating zone and then proceeds to wave soldering. After soldering, excess solder must be removed and the soldered products inspected for defects. A complete wave soldering line can be divided into four major modules: "spray, preheating zone, soldering furnace, and cooling zone".

Reflow soldering: after Solder paste printing is completed and components are properly mounted, the board enters the reflow soldering process for soldering. Then, a cleaning operation should be carried out on the soldered products. A complete reflow soldering line can be divided into three major zone modules: "preheating, heating, and cooling".
