Just a question.... Could it not be done in lamination?? Do a buildup of
the .062 press it then scab on the smaller section...

Most board shops couldn't handle what you are proposing, but if you gave
your bare boards to a machine shop they would have no problems with your
design.

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

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
