Immerse the capacitor in a solution of ethanol (JIS-K-8101) and
rosin (JIS-K-5902) (25% rosin in weight proportion).
Preheat at 80 to 120Dfor 10 to 30 seconds. After preheating,
immerse in eutectic solder solution for 2T0.5 seconds at 230T5D
or Sn-3.0Ag-0.5Cu solder solution for 2±0.5 seconds at 245±5°C.

Fix the capacitor to the supporting jig in the same manner and
under the same conditions as (10). Perform the five cycles
according to the four heat treatments listed in the following table.

Solder the capacitor to 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 of 3 mutually
perpendicular directions (total of 6 hours).

Solder the capacitor to the test jig (glass epoxy boards) shown
in Fig. 2 using a eutectic solder.
Then apply a force in the direction shown in Fig. 3.
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
