During your first de-soldering exercises, you will have noticed that some residual solder re-
mains at the solder point after de-soldering of a component or wire bridge. Is usually collects
in the bore, so that no connection wires can be pushed through anymore.
This is where the de-soldering pump comes in. Tension it first. For this, push down the slid-
ing piston until it catches. The pump’s tip has a small opening and must be held right at the
working point while heating the excess solder with the soldering iron. The distance between
the soldering iron tips and de-soldering pump is only a few millimetres. Once the solder
melts, press the unlocking button at the pump. The sliding piston moves back and a vacuum
forms in the pump, extracting the liquid solder. Several working steps may be required until
all excess solder is removed.
Figure 42: Large amounts of solder, like this solder bridge between resistor and LED, can only be removed
with a de-solder pump.
