Test Method
Solder the capacitor to test jig (glass epoxy board) shown in
fig below. Soldering should be done either by hand iron of
using the reflow method and shall be conducted with care so
that the soldering is uniform and free of defects such as heat
shock. The capacitor shall 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, shall be traversed in approximately 1 minute. This
motion shall be applied for a period of 2 hours in each 3
mutually perpendicular directions (total 6 hours)
