First, the terminals of the capacitor
should be connected together. Then,
as shown in the figure at right, a metal
foil should be closely wrapped around
the body of the capacitor to the
distance of about 3 to 6mm from
each terminal.
Then, the capacitor should be inserted
into a container filled with metal balls
of about 1mm diameter. Finally, AC

The lead wire of a capacitor should be dipped into molten
solder for 2±0.5 sec.
The depth of immersion is up to about 1.5 to 2.0mm from the
root of lead wires.
