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 5

T1sec. 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.

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).
