PRF 31032, which is the spec intended to replace MIL P 55110 has the same
requirements in it for etchback, which are .0002 - .003" when specified by the
master drawing. If no etchback is specified, than a negative etchback of
.0005 is allowable.

Can anyone inform me of the current status of the military requirement re:
etchback? A potential customer's blueprint references 55110D and
specifically calls out for etchback on type 3 boards (multilayer). However,
the board will have a commercial application and, as is common with
blueprint notes, this may be of the "boilerplate" variety. They may be
satisfied with desmear with a little education and persuasion. Thanks to
any who respond.
