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.
Assembly of the SAS PCB
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.
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.
4.
Ceramic
Capacitors
Mounting orientation of no importance.
5.
Light emitting
diodes (LEDs)
Observe the polarity!
With wired LEDs the longer lead is always the
anode (positive pole).
