3.5. 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 3.2.
!
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. Resistor
2. Diode and Zener
diode
3. IC socket
4. Rectifier
5. Ceramic capacitors
6. Voltage regulator
7. Electrolytic capacitors
Terminal strip and pin
8.
headers
9. IC in DIL-housing
Mounting orientation of no importance.
Observe the polarity!
The negative end of the diodes is marked with a ring. This is
shown in the PCB layout.
Mount the socket that way, the markings on the socket show
in the same direction as the markings on the PCB board.
Observe the polarity! The pin connections are printed on the
housing. The longer connecting pin is the positive pole.
Mounting orientation of no importance.
Observe the polarity!
With voltage regulators in TO-packages the unlabelled back
side is marked in the PCB layout by a thick line.
Before soldering, bend the voltage regulator´s pins to 90
degrees, so that you can solder it in corresponding to the
PCB layout with the labelled front side facing upwards.
Observe the polarity! One of the two leads (the shorter one)
is marked with a minus sign.
Insert the IC into the soldered socket.
Do not touch the IC without first discharging yourself by
touching a radiator or other grounded metal parts.
Do not bend the "legs" when inserting it into the socket.
Check that the markings on the PCB, the socket and the IC
show to the same direction.
