A rough guide to how I laid out the isolation pads on my BITX 20/40 board. The copper-clad board is 8 inches x 11 inches (22 cm x 28 cm). I just cut out the pads as needed using tin shears and scrap pieces of copper clad board. Gorrilla SuperGlue is my preferred adhesive. I will put this in the appropriate file on the BITX 20 yahoo group site.
