What Is Wave Soldering?
Wave soldering joins smt components and through-hole parts to a pcb. The machine pushes melted solder into a steady wave shape. The pcb moves over this wave at a certain speed and angle. The solder touches the leads and copper pads that are not covered. Flux cleans the metal before solder sticks to it. The solder flows onto the metal and bonds with it. Capillary action helps fill holes and make strong connections. Wave soldering is best for making lots of boards fast. You can solder many boards quickly and keep the quality high.
Wave soldering makes a steady wave of melted solder. The pcb slides through this wave. The solder touches the leads and pads and forms a strong joint.
