1.10 Final check
Before starting-up, check the printed circuit board once again that all the components
have been inserted properly and with the correct polarity. Check on the soldering side
(the side with the conducting pathways), whether the conducting pathways have been
bridged by the remains of the soldering tin, which can lead to short-circuits and to a
destruction of the components.

Further, it must be checked whether the cut wire-ends are lying on or below the printed
circuit board, which can also lead to short-circuits.

Most of the components sent back for a reclaim have poorly soldered connections (cold
solder joints, solder straps, incorrect or unsuitable soldering tin used, etc.).
