Hello again DC'ers,

I have yet another question about thermal reliefs.  I think I
understand how to calculate the width of a web for a round pad.  How
do you calculate what you need for a "finger" pad?   Let's say it's
.060" wide X .110" long with a .032 drill.  Would it be the same as a
.060" dia round pad? Or do I use 60% of .110" dimension?

All answers are greatly appreciated as usual.  ;-)
