Test Method
Solder the capacitor on the test jig (glass epoxy board) shown
in Fig. 1a using an eutectic solder. Then apply 10N* force in
parallel with the test jig for 10±1sec.
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 heat shock.

Within the specified tolerance
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 of 3 mutually

Solder the capacitor on the test jig (glass epoxy board) shown
in Fig. 2a using an eutectic solder. Then apply a force in the
direction shown in Fig. 3a 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 an 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.
Solderability of

75% of the terminations is to be soldered evenly and
continuously.
