Solder the capacitor on the test jig (glass epoxy board) in the
same manner and under the same conditions as (10).
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 minute. This motion should be
applied for a period of 2 hours in each 3 mutually perpendicular
directions (total of 6 hours).

Solder the capacitor on the test jig (glass epoxy board) shown
in Fig. 2a using an eutectic solder. Then apply a force in the
direction shown in Fig. 3a for 5T1sec. 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.

Preheat the capacitor at 120 to 150D for 1 minute.
Immerse the capacitor in an eutectic solder solution at 270T5D
for 10T0.5 seconds. Set at room temperature for 24T2 hours
(temperature compensating tyoe) or 48T4 hours (high dielectric
constant type), then measure.
#Initial
measurement for high dielectric constant type
Perform a heat treatment at 150W0/Y10D for one hour and
then set at room temperature for 48T4 hours.
Perform the initial measurement.
