Caution:
!
Diodes, electrolytic capacitors, voltage regulators and ICs must be
placed in the right direction! If you solder them the wrong way the
affected parts can be damaged when you connect the power. In the
worst case the whole circuit can be damaged. In any case, a wrongly
connected part will not function.
Next solder in the solder pins, the LED and the terminal strips. Put
together the terminal strips before mounting them.
Finally, insert the ICs into the soldered IC-sockets.
!
Caution:
Do not touch the ICs without first discharging yourself by touching a
radiator or other grounded metal parts. Do not bend the "legs" of the
ICs when inserting them into the sockets. Check that the markings on
the PCB, the socket and the IC show to the same direction.
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.
