4.15 Removing Short Circuits Caused in Soldering
When soldering points and components, conductor paths, etc. are close together, it is pos-
sible that a conductive connection is created by the solder during soldering. The circuit is
not destroyed by this. You can still repair the circuit by removing the excess solder. The
easiest way of removing it depends on amount and position.
The de-soldering pump will help in most cases. It can be used to remove most solder
lumps between two lands or connections of an IC or transistor the easiest way. Heat the
solder lump to be removed with the soldering tip. Once it liquefies, release the arresting
button of the soldering pump after holding it to the working place. Usually the solder can
be removed in a single work step.
Small solder amounts on the PCB can also be removed with the previously cleaned sol-
dering tip. For this, heat the solder and move the tip slightly back and forth. To be safe,
use a fine electronics flat screwdriver or needle to scratch off residues. This removes even
the last, tiny solder residue.
