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 4mm from
each terminal.
Then, the capacitor should be inserted
into a container filled with metal balls
of about 1mm diameter. Finally, AC

Pre-treatment:
Capacitor should be stored at 125±3°C for 1 hr., then placed
at room condition* for 24±2 hrs. before initial measurements.
Should be placed into steam aging for 8 hrs.±15 min. After the
steam aging, the lead wire of a capacitor should be dipped into
an ethanol solution of 25% rosin and then into molten solder for
5+0/-0.5 sec.
The depth of immersion is up to about 1.5 to 2.0mm from the
root of lead wires.

Lead wire should be soldered with uniform coating
on the axial direction over 3/4 of the circumferential
direction.
