3. Safe and correct soldering
Caution: Incorrect soldering can cause dangers t roug fires
and eat. Avoid t ese dangers by reading and following t e directions
given in t e c apter Safety instructions.
Use a small soldering iron wit max. 30 Watt. Keep t e soldering tip
clean so t e eat of t e soldering iron is applied to t e solder point
effectively.
Only use electronic tin solder wit flux.
W en soldering electronic circuits never use soldering-water or
soldering grease. T ey contain acids t at can corrode components
and copper tracks.
Solder quickly: olding t e iron on t e joints longer t an necessary can
destroy components and can damage copper tracks or soldering eyes.
Apply t e soldering tip to t e soldering spot in suc a way t at t e
wire and t e soldering eye are eated at t e same time.
Simultaneously add solder (not too muc ). As soon as t e solder
becomes liquid take it away. Hold t e soldering tip at t e spot for a
few seconds so t at t e solder flows into t e joint, t en remove t e
soldering iron.
T e joint s ould be eld still for about 5 seconds after soldering.
To make a good soldering joint you s ould use a clean and
unoxidised soldering tip. Clean t e soldering tip wit a damp piece of
clot , a damp sponge or a piece of silicon clot .
After soldering c eck (preferably wit a magnifying glass) tracks for
accidental solder bridges and s ort circuits. T is would cause faulty
operation or, in t e worst case, permanent damage. You can remove
excess solder by putting a clean soldering tip on t e spot. T e solder
will become liquid again and flow from t e soldering spot to t e
soldering tip.
