Hi,
I'm routing a board that will be tested by an Automatic Test Equipment line.
I purchased and read the "SMTA/TMAG Testability Guidelines TP-101D" from smta.org:
That document states that I have to make room on the TOP LAYER for 10 plastic PUSH FINGERS (radius 1.6 inches). The purpose of the PUSH FINGERS is to press the board down to the bed of nail.
That seems a lot of room. Does anybody know how many PUSH FINGERS are typically needed?
Thanks, Enrico
