well not quite a pcb but this blank board from Radio Shack:
Would appreciate any help in brainstorming a solution. I could cut it but I
need a small square of about 30MM +- .05MM. Maybe a laser cutting service?
That's about the only thing I can think of.
Score it and snap it a bit oversize and then sand to final dimension.
Circuit board material breaks pretty cleanly with a good score-line on it.

Wet or dry sandpaper. I imagine he really means within .5mm The size board
he is using if it is a home project is possibly only going to have less
than a dozen components. More likely 6-8 components. 30mm x 30mm is about
the size I used for a transistor ignition for a motorcycle. Fits right in
one of the small Radio Shack project boxes. This is the board I used.
Cut it with a box (utility) knife, broke off clean and sanded the edge.
This board is 45mm x 90mm before cutting. I cut it in half and the holes
align with the mounting holes inside the box.
Are you sure that the correct operation of the machine doesn't depend on
other dimensions of the BGA unit? Any reason you can't simply use a
physically real but electrically dead (and thus scrap) BGA package?

Get a square and put it where you want to cut it and score it a couple of
times with a utility knife, hard. Place the scored line over the edge of a
table and break it off at the scored line.
