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 3 mutually perpendicular directions
(total of 6 hrs.).

Solder the capacitor to the testing jig (glass epoxy board) shown
in Fig. 2 using a eutectic solder. Then apply a force in the
direction shown in Fig. 3. The soldering should be done either
with an iron or using the reflow method and should be conducted
with care so that the soldering is uniform and free of defects such
as heat shock.

Solderability of
Termination
75% of the terminations are to be soldered evenly and continuously.
Immerse the capacitor in a solution of ethanol (JIS-K-8101) and
rosin (JIS-K-5902) (25% rosin in weight proportion).
Immerse in eutectic solder solution for 2T0.5 sec. at 235T5D.
