Greetings all; I managed to score some double sided blank pcb today, enough to make a few boards to hold the ABX photo-interrupters (Honeywell HOA2001's) 3x per board for making encoders.
But these encoders have an extra .05" hole pattern spacing, so the whole 3 pin socket pattern for the transistor side of it is only .1" wide for the whole 3 lead pattern with a .05" offset in the center for the third, output pin of the detector. This is getting a bit teeny to mill, so my thought is to bore a .125" hole under each end of it & just run a trace to the edge of the hole, laying the lead down in a puddle of eutectic solder. I have visions at 4AM of this whole thing being about an inch wide and not more than 1.25" long, hopefully by cobbling up a pattern and doing a step & repeat to get 3 of them on the same board, while somehow leaving room to condense the 15 leads into the 5 headed toward emc. With led current limiting r's in 3 of them. Do any of you that have done these conversions several times perchance have some artwork in gcode that could be adapted for this and that you are willing to share with beggars like me?
