Bill,
When I worked at an OEM we consulted our board house and design engineers then settled on a 11 x 17 panel. This gave us very little scrap so the best price from the board house. This also gave us a good amount of population on a panel so we increased the SMT efficiency.

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...

Bill
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...
