Susy:

This is fairly easily done, with fairy accurate results.  It does cost more,
and not all shops have the equipment to do it.  I don't know if the extra
cost it's the extra processing step to mill out the reduced area or to allow
for higher scrap rate.

Subject: [DC] routing the thickness of a board


I've got a good one for the gurus out there!

And engineer just asked me if a rigid board could have an area (an edge
actually) routed such that the overall area of the board is one thickness
(.125), and the routed area is another (.062) See the side view picture
below...


routed area

.062    |_______________________| .125



Other than the obvious issues of controlling routing depth, and I imagine a
hugh cost, what else should I be concerned about? Can it even be done??? We
were thinking that it might be easier to build two boards and fuse them into
one, but would the alignment problems kill that idea?

TIA for any help,
Susy
