Wave soldering is a bulk soldering process used primarily for through-hole components. During this process, the bottom of the PCB passes over a wave of molten solder created by a wave soldering machine, which instantly forms electrical and mechanical connections.
If you’re asking what is wave soldering, it’s one of the oldest and most efficient machine soldering wave methods, still widely used today for cost-effective, high-volume PCB production.
The wave soldering process at Manufyn follows these precise steps:
Liquid flux is applied to clean PCB pads and leads.
The board is gradually heated to prevent thermal shock and activate flux.
The PCB bottom side passes over the molten solder wave in our automatic wave soldering machine.
Controlled cooling solidifies solder joints and completes the assembly.

Wave soldering is a machine soldering process where PCBs pass over a wave of molten solder to bond through-hole component leads.
A wave soldering machine generates a standing wave of molten solder and moves PCBs across it to solder all exposed pads and leads simultaneously.
The wave soldering process involves flux application, preheating, contact with molten solder wave, and cooling to create strong solder joints.
The key difference between reflow and wave soldering lies in component types—wave is for through-hole, reflow is for surface-mount—and the heating mechanism.
Yes, wave soldering remains essential for power boards, transformers, connectors, and hybrid assemblies where through-hole strength is needed.
Yes, our automatic wave soldering machines offer programmable speed, temperature, and wave height control for repeatable results.
Absolutely. We handle mixed-technology PCBs with both SMT and through-hole components using reflow and wave soldering processes in sequence.
Advanced wave soldering equipment ensures uniform heat transfer, faster cycle times, and compatibility with various board sizes and thicknesses.
Yes, our systems are configured to handle both leaded and lead-free solder alloys while maintaining thermal consistency and IPC standards.
The advantages of wave soldering include speed, consistency for through-hole parts, cost-efficiency, and excellent joint strength in high-load environments.
