Performing a visual check
Perform a visual check after the assembly of the module and remove
faults if necessary:
Remove all loose parts, wire ends or drops of solder from the PCB.
Remove all sharp wire ends.
Check that solder contacts which are close to each other are not
unintentionally connected to each other. Risk of short circuit!
Check that all components are polarised correctly.
When you have remedied all faults, go on to the next part.
Observe the polarity!
Solder diodes that way, their bodies are
standing upright on the PCB. Observe the
diodes´polarity!
Put together the terminal strips before
mounting them.
Observe the polarity!
With wired LEDs the longer lead is always
the anode (positive pole).
Put together the terminal strips before
mounting them.
Insert the ICs into the soldered socket.
Do not touch the ICs without first
discharging yourself by touching a radiator
or other grounded metal parts.
Do not bend the "legs" when inserting them
into the sockets. Check that the markings on
the PCB, the socket and the IC show to the
same direction.
