3. Safe and correct soldering
Caution:
Incorrect soldering can cause dangers through fires
and heat. Avoid these dangers by reading and following the directions
given in the chapter
Safety instructions
.
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 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.
Apply the soldering tip to the soldering spot in such a way that the
wire 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.
The joint should be held still for about 5 seconds after soldering.
To make a good soldering joint you should 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.
After soldering check (preferably with a magnifying glass) tracks for
accidental solder bridges and short circuits. This would cause faulty
operation or, in the worst case, permanent 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.
