This is from the classic computer mailing list.  I thought some of you
might find it interesting.

Just a note that if you want to create PCB Panels yourself and save a 
bit of money, I suggest you load GerbMerge 
(http://claymore.engineer.gvsu.edu/~steriana/Python/gerbmerge/) 
somewhere and use it.  It takes std Gerber files as input and will 
panelize multiple designs.  I can vouch that it works well.  If you do 
use it, I would set the design spacing to 4mil or so and ask the PCB 
house to do a 'V-groove" on the cut lines.  It makes for easy 
separation.  As well, if you do decide to have assmebly done, you can 
pay for 1 stencil instead of multiple.

Here's an example:  
http://www.jbrain.com/2009/07/15/rom-el-test-boards/  In this one, I 
tried something different with the breakaways, but I would recommend 
V-grooves over the idea this picture shows.
