Is this possible in 17.2? I have a customer that wants me to provide panelized artwork but there does not appear to be a way to do it within 17.2 - only 3rd party software?
multi-array for fabrication? Have him check with his intended fabricator first. Hate to see you go through that and find out fabricators delete it and do it differently to match their process.
Array for assembly is different. This usually involves having fiducials and maybe tooling holes for the SMT machine to align with and handle the bare board.
A single (odd-size or shape) board in a square-ish assembly panel should be straightforward to do in Cadence..
A common mistake is leaving off the three fiducial optical targets needed for alignment and calibration by the stencil and SMT placement machines. That could be bad.
