§Use a small soldering iron with max. 30 Watt. Keep the soldering tip
clean so the heat of the soldering iron is applied to the solder point
effectively.
§Only use electronic tin solder with a flux.
§When soldering electronic circuits never use soldering-water or
soldering grease. They contain acids that can corrode components
and copper tracks.
§Solder quickly: holding the iron on the joints longer than necessary
can destroy components and can damage copper tracks or
soldering eyes.
§Observe correct polarity orientation of semi-conductors, LEDs
electrolytic capacitors and integrated circuits before soldering and
ensure that the solder time does not exceed 5 seconds, otherwise
components can be damaged.
§Apply the soldering tip to the soldering spot in such a way that the part
and the soldering eye are heated at the same time. Simultaneously add
solder (not too much). As soon as the solder becomes liquid take it
away. Hold the soldering tip at the spot for a few seconds so that the
solder flows into the joint, then remove the soldering iron.
§Do not move the component for about 5 seconds after soldering.
§To make a good soldering joint you must use a clean and
unoxidised soldering tip. Clean the soldering tip with a damp piece
of cloth, a damp sponge or a piece of silicon cloth.
§Cut the wires after soldering directly above the PCB solder side with
a side cutter.
§After placing the parts, please double check for correct polarity.
Check the PCB tracks for solder bridges and short circuits created
by accident. This would cause faulty operation or, in the worst
case, damage. You can remove excess solder by putting a clean
soldering tip on the spot. The solder will become liquid again and
flow from the soldering spot to the soldering tip.
