Dennis,

If the board is 2 layer, the board size can be bigger. The rule of thumb is
.75"
border for handling and .100" between parts for routing.
If you score vs rout the part size can increase accordingly. Scores require
zero
spacing.

I have seen suppliers fudge the borders sometimes but this is a risk for
handling damage and imaging/plating problems.

16.5 X 11.2 is a standard (safe) part size.

Good morning everyone,

Hope everyone had a great New years. Quick
question. On a 18 X 24 panel what is the maximum
size of an individual board and still get TWO boards
per panel? Please no "contact your board vendor"
replies. I have documentation for four different
vendors and each has something different. And I
understand that each will be different. I am curious
how these vendors stack up with the rest of the
industry. I've seen sizes from 16.00 X 10.90
(the smallest) to 16.50 X 11.20 (the largest).

What is realistic? Is the 16.00 X 10.90 too
conservative and the 16.50 X 11.20 too large??

Thanks for the replies
Dennis
