Hi, I'm about to go to fab on a hobby PC board, but have a free area on it that is 0.77" x 0.585" . I would like to put some spare footprints in it, in case I want to fix something later. Any suggestions as to what I should put there? The entire board is about 9" x 9", consisting almost entirely of analog (dc-dc converter) circuitry. I was thinking I should at least put down some 1206 surface mount pads. Anything else?
