S88-4

English

In schools, training centres, clubs and workshops, assembly must be
supervised by qualified personnel.
In   industrial   institutions,   health   and   safety   regulations   applying   to
electronic work must be adhered to.

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  or   a  regulated
soldering iron.  

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.

Insert the component connecting pins into the PCB´s holes as far as
possible   without   force.   The   components   should   be   close   to   the
PCB`s surface.  

Observe correct polarity orientation of the parts before soldering.

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
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.
