Solder the capacitor to the test jig (glass epoxy board) using a
eutectic solder. Then apply 10N* force in parallel with the test
jig for 10T1 sec. 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

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
