Test Method
Appearance
No defects or abnormalities.
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.
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 120D for 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 2T0.5 seconds at 245T5°C.
Solderability of

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