Hello to everyone!

Can anybody tell my why printmount electrolytics have always
a higher livetime rating than studmount or clamp-mount types.
This would be especially interesting as the overall impact
of the capacitor mounting styles is (IMO) reverse.(I do not
consider having massive CAP-Banks on a PCB to be reliability
-enhancing, if not very dedicated efforts to counter it are
undertaken.) But this (For exp. mechanical work at the pins
by vibration/shock acting on the Capacitor) affects the com-
ponent too. So what is behind this difference?

Regards M. Schneider
