Brief Introduction of DIP Wave Soldering Equipment
1. Definition
Wave soldering equipment refers to that the molten solder is sprayed by an electric pump into a solder wave crest required by the design, so that the printed board pre-installed with components passes through the solder wave crest to realize the soldering ends or pins of the components and printing A soldering device for the soldering of mechanical and electrical connections between board pads.
2. Main components
The wave soldering machine is mainly composed of a conveyor belt, a heater, a tin bath, a pump, and a welding spray device. Mainly divided into flux addition area, preheating area, welding area, cooling area
3. Working principle
Wave soldering is to use a wave soldering machine to complete the welding of all the solder joints on the print at one time. The main structure is a temperature-controlled tin melting cylinder with a mechanical pump and a nozzle with a special structure. The mechanical pump can be continuous according to the welding requirements. The liquid tin wave is continuously pressed out from the nozzle, and when the printed board enters at a certain speed from the conveyor, the solder continuously overflows to the printed board surface in the form of a wave crest for welding. The operating process is: preparation before soldering → coating flux →preheating→wave soldering→cooling
