Assembly
Proceed according to the order given in the list below. First solder the
components on the solder side of the PCB and then cut the excess
wires with the side cutter. Follow the instructions on soldering in
section 3.
Caution:
Several components have to be mounted according to their polarity.
When soldering these components the wrong way round, they can be
damaged when you connect the power. In the worst case the whole
circuit can be damaged. At the best, a wrongly connected part will not
function.
1.
PCB sockets
2.
Resistors
Mounting orientation of no importance.
3.
Diodes
Observe the polarity!
The negative end of the diodes is marked with
a ring. This is shown in the PCB layout.
4.
Relays
The mounting orientation is given by the
layout of the pins.
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.
