Appearance No defects or abnormalities
Capacitance Within the specified tolerance
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 perpendic-
ular directions (total of 6 hours).

Solder the capacitor on the test jig (glass epoxy board) shown
in Fig. 2 using a eutectic solder.
Then apply a force in the direction shown in Fig. 3 for 5±1 sec.
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.

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 120°C for 10 to 30 seconds. After preheating, immerse in
eutectic solder solution for 2±0.5 seconds at 230±5°C or
Sn-3.0Ag-0.5Cu solder solution for 2±0.5 seconds at 245±5°C.
