Re: gEDA-user: Blind & Buried Vias

[Steve Meier <smeier@xxxxxxxxxxxxxxxxxxx>]

Neil,

If the requirement is not to have the board not make electrical contact
with skin, why not put an insulator on the back of the board? There are
various types of tapes and even sprayes that can be used to encapsolate
one or both sides.
