The capacitor should not be damaged when AC1500V(r.m.s.)
are applied between the lead wires for 60 sec.
First, the terminals of the capacitor should be connected
together. Then, as shown in figure at right,
the capacitor should be immersed
into 10% salt solution up to a position
of about 3 to 4mm apart from the
terminals.
Finally, AC1500V(r.m.s.) is applied
for 60 sec. between the capacitor lead
wires and electrode plate.

Lead wire should be soldered with uniform coating
on the axial direction over 3/4 of the circumferential
direction.
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.
Temp. of solder: Lead Free Solder (Sn-3Ag-0.5Cu) 245±5°C
H63 Eutectic Solder 235±5°C
