Dongguan PURE-AIR Technology has a long-term cooperative relationship with many PCB circuit board companies, and provides these companies with many process fume purification equipment such as portable welding fume extractor uk and welding fume extraction equipment!

Next, let everyone understand what wave soldering is!

The wave soldering machine is a kind of solder wave that relies on the effect of pump pressure to make the surface of the molten liquid solder produce a special shape of the solder wave. When the assembly assembly with the electronic device is inserted according to the solder wave at a fixed angle of view, spot welding is generated in the soldering area of the foot. Production process.

A wave soldering machine is mainly composed of conveyor belt, electric heater, tin tank, pump, and solder paste polyurethane foaming (or sprayer) equipment. The key is divided into solder paste plus zone, preheat zone, electric welding zone, refrigeration zone,

During the whole process of the components being transported by the chain conveyor belt, the preheating is carried out in the preheating zone of the machine (the preheating of the components and the temperature to be achieved are still controlled by the predetermined temperature profile). In specific electric welding, it is generally necessary to control the preheating temperature of the component surface, so many machines and equipment have upgraded the corresponding temperature inspection equipment (such as infrared detectors).

After preheating, the components enter the lead bath for electric welding. The tin tank is filled with molten liquid solder, and the nozzle at the bottom of the steel tank sprays the molten solder out for wave soldering in a fixed pattern, so that when the component welding surface is heated according to the wave, the solder wave is also heated at the same time. Wet the welding area and expand and fill, and finally complete the whole process of electric welding.

This is the whole process of the entire wave soldering work, of course, it is far more complicated than this article. It is very strange why Dongguan PURE-AIR Technology knows these contents. This is because when we provide fred welding fume extractor and reflow welding fume extractor equipment for these companies for a long time, we often have to communicate with these companies.
