Required tools and materials
Make sure you have the following tools and materials ready for use:
§
an electronic soldering iron (max. 30 Watt) with a fine tip,
§
a soldering iron stand,
§
a tip-cleaning sponge and a heat-resistant mat,
§
a small side cutter and wire stripper,
§
a pair of tweezers,
§
tin solder (0,5 mm. diameter),
§
enamelled copper wire or thin connecting wire,
§
LEDs for the lights,
§
if necessary: series resistors for the front lights.
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
. If you have had training in soldering you
can skip this chapter.
§
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
