Reflow oven and wave soldering

Firstly,the wave soldering is to melt the tin strip into liquid through the tin slot, and use the motor to stir the wave to form the wave peak, so that the PCB and the parts are welded together, generally used in the welding of the hand plug-in and the glue board of the SMT. Reflow soldering is mainly used in the SMT industry. It is heated by hot air or other thermal radiation, and the solder paste printed on PCB is melted with the solder.

Secondly. the process is different: wave soldering should first spray flux, then preheat, weld and cooling area. The reflow passes through the preheating zone, the recirculation zone and the cooling zone. In addition, the wave soldering is suitable for hand plugged plate and point plate, and requires all components to be heat-resistant. The surface of the over wave peak can not have SMT solder paste. The SMT solder paste can only pass the reflow welding, and the wave soldering can not be used.

Reflow soldering: by remelting the ointment paste that is pre - distributed to the pad of the printed circuit board, a mechanical and electrical connection between the surface of the surface of the adhesive component terminal or pin and the pad welding pad is realized. It is a step in SMT (surface mount technology).

Wave soldering: wave soldering is a kind of automatic soldering equipment with high temperature heating to weld plug-in components. From function, wave soldering is divided into lead wave soldering, lead-free peak welding and nitrogen wave soldering. From structure, a wave soldering is divided into four parts: spray, preheat, tin furnace and cooling.

Difference: wave soldering is used to weld plug-in components, and reflow soldering is used for welding of mounting elements.
