Hi Ioan,

Why design a special board for assessing component placement. I would think
that your board supplier(s) occasionally have fabricated boards that are
scrapped for one reason or another. Why not utilize the scrap of your
current production designs (assuming pad layout is not the reason boards are
scrapped) to assess component placement. Seems to me that would be a more
cost effective approach and would likely be more representative of what your
trying to determine. Or am I missing something?

Best Regards,

Joe Russeau

Subject: [TN] SMT placement test PCB

would serve for periodical testing of the placement of our machines. We have
Fuji CP6 and IP3, just FYI as I don't think the board should be speciffic to
a machine in particular.

board sufficient?
