Thermal danger
A hot soldering iron or liquid solder accidentally touching your skin can cause skin burns. As a
precaution:
 use a heat-resistant mat during soldering,
 always put the hot soldering iron in the soldering iron stand,
 point the soldering iron tip carefully when soldering, and
 remove liquid solder with a thick wet rag or wet sponge from the soldering tip.
Dangerous environments
A working area that is too small or cramped is unsuitable and can cause accidents, fires and
injury. Prevent this by working in a clean, dry room with enough freedom of movement.
Other dangers
Children can cause any of the accidents mentioned above because they are inattentive and not
responsible enough. Children under the age of 14 should not be allowed to mount vehicle
decoders.
Caution:
Little children can swallow small components with sharp edges, with fatal results! Do not
allow components to reach small children.
In schools, training facilities, hobby and self-help workshops, the assembly, installation and
operation of electronic modules must be supervised by trained personnel.
In commercial facilities, the relevant accident prevention regulations must be observed.
3.2. 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 soldering iron with temperature control, which you set to approx. 300 °C.
 Only use electronic solder with a flux.
 Never use soldering fluid or soldering grease when soldering electronic circuits. These
contain an acid that destroys components and conductor paths.
 Solder quickly: Soldering for too long can detach solder pads or tracks or even destroy
components.
 Hold the soldering tip on the soldering point so that it touches the wire and the pad at the
same time. Add (not too much) solder simultaneously. As soon as the solder begins to flow,
remove it from the soldering point. Then wait a moment for the solder to flow well before
removing the soldering iron from the soldering joint.
 Do not move the created solder joint for about 5 seconds.
 A clean, non-oxidized soldering tip is essential for a perfect soldering joint and good
soldering. Therefore, before each soldering, wipe off excess solder and dirt with a damp
sponge, a thick damp cloth or a silicone wiper.
