Click here to download a powerpoint file with our charts of this pcb. All the images below are hyperlinked to larger, higher-resolution images so if you click on them, the bigger image should load into your browser. Here's a drawing of the Buffer / Inverter PCB as seen from the top. In this case, we're pretty sure we've captured the exact location of the pads, but even if there are a couple little discrepancies, you can very accurately see where there's a 1/10 in spacing vs a 2/10 in spacing, for instance:
The following drawing illustrates how the traces hook things up. Ground - Red. The red lines show the pads that hook up to Ground by way of the top traces. The dark red lines (there are only a couple dinky ones) show a couple pads connected to ground by way of a trace on the back. -15V - Yellow (some traces are on front, some on back) +15V - Orange (some traces are on front, some on back) Other traces on front - Light Green Other traces on back - Blue
