Soldering involves a
process of joining two or more metals by melting and putting filler
metal into the joint. Flux is used to facilitate the soldering
process. Soldering filler materials are available in different alloys
for differing applications. In electronics assembly, the alloy of 63%
tin and 37% lead is the most commonly used.
When you buy the Electronic Components for your device you should know the
soldering advice for each component. Some components require special
care while soldering. Here is the soldering advice for different
components:
- Resistors: No special precautions.
- Diodes: Must be connected the correct way round. a= anode, k= cathode
- IC holders: Ensure that the notch is at the correct end.
- Capacitors, electrolytic: These are marked + or – near one lead and must be soldered the correct way round.
- ICs: Carefully insert the ICs the correct way round in their holders after the all soldering is complete.
- Battery clips and buzzers and other parts with wires: Red (+) and black( –) wires must be connected in the correct order.
Now when you know the
precautions for different devices, have a look at the safety
precautions you need to follow when soldering.
Soldering Safety
Precautions
1. Work in an
environment that is well lit and ventilated.
2. Unplug the soldering
iron when it is unattended.
3. Be careful to keep
clothes, hair, power cables etc away from the soldering Iron tip and
the metal shaft.
5. Always handle the
iron by the plastic handle.
6. Do not point the
circuit towards yourself whilst trimming down component legs.
Soldering Iron
1. Never touch the
element of the soldering iron....400°C!
2. Hold wires to be
heated with tweezers or clamps.
3. Keep the cleaning
sponge wet during use.
4. Do not put the
soldering iron on the workbench, return the soldering iron to its
stand when not in use.
5. Turn unit off and
unplug when not in use.
These simple tips will
prevent you and your device from any damage. Any error can cause
serious damage.
