RCD-2
1.
Resistors
(except R3, R15,
R24, R26, R27
and R28)
Mounting orientation of no importance.
2.
Diodes 1N400x
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.
Voltage regulators Observe the polarity!
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.
5.
IC sockets
Mount the sockets that way, the marking on
the sockets show in the same direction as
the markings on the PCB board.
6.
Transistors
(except Q3)
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.
7.
Solder pin
8.
Resistors
R3, R15, R24,
R26, R27 and R28
Solder the resistors that way, their bodies
are standing upright on the PCB.
9.
Electrolytic
capacitors
Observe the polarity!
One of the two leads (the shorter one) is
marked with a minus sign.
