Appearance No defects or abnormalities.
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).

Capacitance Within ±5% or± 0.5pF
Solder the capacitor on the test jig (glass epoxy board) shown in
Fig.1 using an eutectic solder. Then apply a force in the direction
shown in Fig 2 for 5±1 seconds. The soldering should be done
by the reflow method and should be conducted with care so that
the soldering is uniform and free of defects such as heat shock.
