Solder the capacitor on the test jig (glass epoxy board) shown
in Fig. 2a using a 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 a 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.
