Wave soldering is a tin bar into a liquid state by tin slots, using a motor to form a peak, allowing the PCB to weld to the part, generally used in the hand-in-in-box soldering and SMT glue plate. Re-flowing welding is mainly used in the SMT industry, which is conducted by hot air or other thermal radiation, melting the solder paste printing on the PCB and welded.

Different: Wave weld the flux, and then warmed, welded, and cooling zones. Re-welding after a preheating zone, reflow area, and cooling zone. In addition, wave welding is suitable for hand-switched plates and dispensing plates, and all components should be heat-resistant, and the surface of the peak can not have the components of the SMT solder paste, the SMT solder paste can only be re-flowing, can not Welding from the wave.

Reflow soldering: The surface of the paste paste is pre-allocated to the printed circuit board welding pad, realization surface. The adhesive component terminal or pin is mechanically connected to the electrical connection between the printed circuit board pads. It is a step in SMT (Surface Pack Technology).

Waves welding: wave welding is an automatic solder device for welding the insert element by high temperature heating.

It can be used, the wave welding is solder welding, lead-free wave soldering and nitrogen wave soldering, from the structure, one wave

The peak welding is spray, preheating, tin furnace, cooling four parts.

Difference: Water welding is used to weld the plug-in element, and reflow soldering is used to weld the mounting element.
