Proto Board-3U. Size 3.9" x 6.3" x 1/16"
General purpose prototyping board with holes in copper patterns in groups of six. IC's and other DIP components may be placed across gaps and there are plenty of holes for interconnections. Holes are, of course, spaced on .10" center and each is .037" in diameter.
The board accepts a 96 pin DIN-41612 VME connector for backplane or board-to-board connections; holes are provided for latches.
The board material is etched FR-4 glass-epoxy with one ounce copper on one side, tinned for better soldering. The board size is 3.9" x 6.3 x 1/16" (100 x 160 x 1.6mm). Total holes are 38 rows by 62 columns.
