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
R1, R2, R3
Mounting orientation of no importance.
2. IC sockets Mount the sockets that way, the markings on
the sockets show in the same direction as the
markings on the PCB board.
3. Resistors
R4 to R19
Solder the resistor that way, their bodies are
standing upright on the PCB.
Mounting orientation of no importance.
4. Resistance
networks
Observe the mounting orientation!
The common connection is marked which is
also shown on the PCB print.
5. Ceramic
cpacitors
Mounting orientation of no importance.
6. Transistor Observe the polarity!
The cross section of transistors for a low
power rating in SOT-packages is shown in the
PCB layout.
