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. Resistors
2.
Wire bridges Br1
to Br4
3. IC sockets
4. Transistors
5. Diodes
6.
Terminal strips
Mounting orientation of no importance.
Use the off-cut wires of the resistors.
Mount the sockets that way, the markings on
the sockets show in the same direction as the
markings on the PCB board.
Observe the polarity!
The cross section of transistors for a low
power rating in SOT-packages is shown in the
PCB layout.
Observe the polarity!
The negative end of the diodes is marked with
a ring. This is shown in the PCB layout. Solder
the diodes that way,their bodies are standing
upright on the PCB.
Put together the terminal strips before
mounting them.
