When mounting the capacitor to the substrate, it is important to
consider carefully that the amount of solder (size of fillet) used has a
direct effect upon the capacitor once it is mounted.

CA series : Please refer Page 19.
a) The greater the amount of solder, the greater the stress to the
elements. As this may cause the substrate to break or crack, it is
important to establish the appropriate dimensions with regard to the
amount of solder when designing the land of the substrate.
b) In the situation where two or more devices are mounted onto a
common land, separate the device into exclusive pads by using
soldering resist
