Many moons ago when I worked for the Burroughs Corporation, we built 10's of thousands of boards that not only had a 45° chamfered edge at the fingers about 10" wide, but there also was a lead in starting at the furthest ends sequencing in to the center.

Yes, it can be done. Current CNC routing might be difficult to maintain Z accuracy due to board deflection. The boards mentioned above were done on a manual router table.

Subject: [TN] Chamfered PCB

I've got a request if a PCB can be chamfered. My initial inclination is yes, but I've never been asked.

What makes this difficult is the small size and one side in rounded.

PCB is 35.95mm long X 12.10mm wide (standard 1.57mm [0.062in] thick)

Chamfer would be 45 or 55 degrees all the way around, except the one width (12.1mm) side would be straight.

Shape is pcb is like this:
