Panelization of small board

Sagetech

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.

    Hello Sagetech,

    The latest release in 17.4 s008 added the Fab panelization tool option in the OrCAD Pro license. Check them once it may help you.

    Hello 

    Where did you get that information ?

    Tom, not to sure why your customer is asking for a panelized artwork as on it's own the Artwork is useless. To be able to use such artwork the drill file will also have to be stepped and repeated as will any scoring or mouse tabs for the board.

    To echo what RFinley said, Your far better off letting the board-house do this because they have the cam and drill editors etc to actually fabricate a panel based on your single board gerber files. This would be a panel they can make physical boards from "Based on their process" and equipment they use.

    All the best.

    Excellon1 and RFinley, I fully agree. 

    My 2 cents:

    I work with organizations in my company that designs all of their layouts panelized.  I have never gotten a reason why they do this, it makes no sense to me.  They are a fab house and don't know what material and DFM rules any gab house follows.  This may lock them into a given fab house.

    There is a very good document presented by Albert Schweitzer:   CostDrivers in Manufacturing of PCBs  weblink: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwj4jt_To-HrAhXcHzQIHUzsCioQFjAAegQIBBAB&url=http%3A%2F%2Fwww.flowcad.ch%2Fcms%2Fupload%2Fdownloads%2FPCBRoadshow2017CostDriver.pdf&usg=AOvVaw1aLl59JIhjnoaunSQbaxHM

    One of the top cost drivers for a PCB is: Panel Utilization

    I prefer to leave it to the fabricator to panel the bards, they are the experts and can do a better job at creating a paneled design.
