what is the scenario?

The more the solder joint the more capacitors are prone to mechanical stress or the lesser the more mechanical stress?

what about uneven solder joint fillet? one side is 25% then other side is 75% or 100%?

please put in your 2 cents. appreciate it in advance...thanks for the help.

Here's one take on what you seem to be asking: * After a point, more solder is more stress than the proper amount of solder would produce. * Asymmetrical amounts of solder produce more stress than balanced amounts of solder would produce.
