Have you considered V-scoring your panels as a way of minimizing waste. Most shops have this capability. after assembly you break the boards out of the subpanel along the V-score line.

Thanks for responding Lee...
After doing some investigation... I'm thinking a 8X10 assembly panel would
work well for our assembly folks and still be dividable into a 18X24 or
12X18 panel without difficulty...
One shop recommended 8.2 X 11.2 as the maximum assembly panel so it gave
them room to put a .100 in router bit down the center and ¾ in. all round
the perimeter... another wants .400 in between the boards... still another
has many more standard panel sizes to work from and sees no problem with
many different configurations... it's a bit 'non-standard' if you ask me...
but that's what makes the challenge interesting... I'm wondering what other
folks are using for their standard assembly panels...

18x24 is by far the most popular panel size used in the industry. Most
Chinese shops, however, often tailor the panel size to the board or subpanel
to optimize panel utilization. I suggest if you are using a Chinese shop you
consult with them and take advantage of this benefit. I worked in the AT&T
Richmond shop from the day it opened till it was shut down and we never
considered multiple sizes to be manageable. After visiting many of the
shops in China, I have come to realize that not all knowledge resides in
North America.

Hi TechNet...
We are re-evaluating our board assembly panel sizes and want to get the best
yields from our vendor's manufacturing panels when we select the final size
of our 'standard' assembly panel...
What is your PCB manufacturing 'standard' panel size for glass/epoxy type
materials??? Some PCB vendors tell me they have a working panel size of
18x24 inches... what do you use? And why?
Thanks in advance for your help...
