you need a soldering iron (around 25W), 60/40 solder and optionally
a soldering iron holder. Note that you'll probably want one unless
you're the careful type and you're sure you won't burn up anything.
The soldering iron is extremely hot so DO NOT touch the metal parts
of the soldering iron! Also, try not to breath the fumes from the
solder. Work in a well ventilated area. Before you solder, you must
tin the tip. Simply wait for the soldering iron to heat up, apply
a coat of solder on the tip, and wipe it with a wet sponge. Now,
to solder the components onto the board, cut the leads at the proper
length. Stick the component's leads through the proper holes and
bend it so that It'll stay still. Put the soldering iron tip so
that it's touching the lead and the copper at the same time. Then
apply the solder on the lead (not on the tip of the soldering iron).
Let the joint cool by itself. PRACTICE A LOT!
small tip: Whenever you remove insulation from an end of the wire,
apply a coat of solder to the exposed end. It will be much easier
to handle after that.
is how a solder joint should look like:
Amount of Solder
a) Minimum amount of solder
c) Excessive solder
a) Bad solderability of terminal wire
b) Bad soldering of PCB
c) Bad soldering of terminal wire and PCB
