11. Assembly stage II: Sight inspection of the circuit board
Prior to commissioning the circuit, check once again that all components are positioned correctly and have the right polarity. Check on the
soldering side (strip conductor side) whether strip conductors were bridged by solder residues, as this may lead to short circuits and the
destruction of components. You further have to check whether cut off wire ends are located on top or below the circuit board, as these may also
lead to short circuits.

Most of the "defect" construction kits returned to us can be attributed to bad soldering (cold soldering spots, soldering bridges, wrong
or unsuitable solder, etc.).
