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

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?
