Hi TechNetters,

        I'm trying to determine how many PCB's will fit comfortably on a
standard sheet of laminated FR4. This is for a single sided rectangular
board 2.5" x 3.5". Here's what I need to know:

1. How big is a standard sheet of FR4?

2. How much room do I allow between each PCB for routing bits?

3. How much material do I need to allow for around the edge of the sheet as
unusable?

Thanks in advance,

  -Michael Hiteshew
