Hello everyone I am looking for some help I am on a new project we are
going to be drilling .020 solid copper and then bonding core
(outters-kind of) to the copper what we are concerned with is if the
prepreg will fill the holes completlyin the center, is there a formula
to figure this out?We are going to do a dry run with some core and then
look at it but is there another way?

               Thank You Bill Dworak
