How does a desoldering station work?

A desoldering station is a tool used to remove soldered components from printed circuit boards (PCBs) or other electronic assemblies. It does this by melting and removing the solder that binds the component’s leads to the PCB.

The desoldering station consists of a heating element, a vacuum pump, and a tube for suction. It works in four main steps:

  1. Heating the solder joints:
    The first step is to heat the joint with the heating element to melt the solder. There are different types of heating elements that can be used, like infrared or hot air, but the most common is a ceramic heater.
  2. Vacuum Pumping:
    Once the solder melts, the vacuum pump sucks it up through the desoldering tool nozzle. The pump must be powerful enough to create a vacuum in the nozzle and the tube that pulls out the molten metal.
  3. Removing dismantled/cleaned Component:
    The removal of the component may require additional tools such as tweezers or pliers, Once component is removed its pins/leads are cleaned of any remaining (old) solder.
  4. Solder recovery for Recyclability:
    Some desoldering stations contain a solder recovery system that separates the solder and filteres it putting out ready for reuse.

Overall, a desoldering station is an essential piece of equipment for anyone working with electronics, It helps reduce time spent on de-soldering manually while also creating minimal damage to the electronic components being removed.
