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.

  Subject: [TN] Standard panel size?...


  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...
