Ahhhh but what if expected was 10 of each? How many panels to test
or process? How do you test? Flying Probe in array format?  It's very
difficult to track ET callouts on a multiple part number array. Can you
ship in array format for assembly? Will you take X outs? If you build
as lot charge yield of 10 panels (or min lot charge) how does a
fabricator
quantify scrap? (Cost of quality approach) Are all the parts similar
in shape and copper density? Can they be placed on the panel
symetrically so when laminated there is no swimming or part / panel
distortion from pressing?

        These and alot more come to mind when thinking about
building many different part numbers on the same panel. Sometimes,
it produces huge headaches. And the potential cost savings from
tooling may not be worth it.

Just my .02 cents....

Groovy
