Hi, this thread seems interesting, but...
When do you realy need a hole *not* to be plated? Specialy it that will be an extra manufacturing cost (you may negociate and not be billed, but the cost is there) What I usualy do, and manufacturers understand is this: the pad *and* the hole with the same size. This is usefull just in case where there may be doubt, and may otherwyse thing that I made a mistake. This usualy result in a hole that *is* metalized, but has no copper around it. Sometimes for mechanical reasons I can even make it just a little bigger just because it will be more rigid so a plastic fixture may need the extra space. I am interesting in some feedback :) Alain dennevi escreveu: > Hi again > > Your exactly right Pedro. The problem is that there's no good way of telling > the pcb-maker.
