Test Method
–
Visual inspection
Using calipers and micrometers
No failure should be observed when DC500V is applied between
the terminations for 1 to 5 sec., provided the charge/discharge
current is less than 50mA.
The insulation resistance should be measured with DC250±50V
and within 60±5 sec. of charging.
The capacitance/D.F. should be measured at a frequency of
1±0.2kHz and a voltage of AC1±0.2V(r.m.s.).
The capacitance measurement should be made at each step
specified in the Table.

Perform a heat treatment at 150Y ^W100°C for 60±5 min. and then
let sit for 24±2 hrs. at room condition.*
Solder the capacitor to the testing jig (glass epoxy board) shown
in Fig. 1.
Then apply 10N force in the direction of the arrow.
The soldering should be done using the reflow method and
should be conducted with care so that the soldering is uniform
and free of defects such as heat shock.

Glass Epoxy Board
Fig. 1
Solder the capacitor to the test jig (glass epoxy board).
The capacitor should be subjected to a simple harmonic motion
having a total amplitude of 1.5mm, the frequency being varied
uniformly between the approximate limits of 10 and 55Hz. The
frequency range, from 10 to 55Hz and return to 10Hz, should be
traversed in approximately 1 min. This motion should be applied
for a period of 2 hrs. in each of 3 mutually perpendicular
directions (total of 6 hrs.).
