Solderability of
Termination
75% of the terminations are to be soldered evenly
and continuously.
Solder the capacitor to the testing jig (glass epoxy board) shown
in Fig. 2.
Then apply a force in the direction shown in Fig. 3.
The soldering should be done using the reflow method and
should be conducted with care so that the soldering is uniform
and free of defects such as heat shock.
