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 Mounting orientation of no importance.
2. Diodes Observe the polarity!
The negative end of the diodes is marked with
a ring. This is shown in the PCB layout.
3. Ceramic
Capacitors
Mounting orientation of no importance.
4. IC sockets Mount the sockets that way, the markings on
the sockets show in the same direction as the
markings on the PCB board.
5. Fuse Mounting orientation of no importance.
6. Transistors Observe the polarity!
The cross section of transistors for a low
power rating in SOT-packages is shown in the
PCB layout. With transistors for a high power
rating in TO packages (e.g. BD types) the
unlabelled back side is marked in the PCB
layout by a thick line.
