Unless you build only 2-sided boards there has to be prepreg in the board somewhere so the board can't be built with just laminate. If your note is calling out something that doesn't make building the board possible, maybe it was overlooked. And if your board is only 2-sided, I can't see that it matters. The laminate was made using a foil lamination process. It's just a matter of where it occurred. > ---------- > From: > [log in to unmask][SMTP:[log in to unmask]] > Reply To: TechNet E-Mail Forum.;[log in to unmask] > Sent: Monday, March 18, 2002 8:05 AM > To: [log in to unmask] > Subject: [TN] Foil Lamination > > The call-out on our fab drawings states to use copper clad epoxy laminate > FR4 base material.
