I agree with Jeffrey. At most of the companies I have worked for, the numbers he gives are the standard. One company insisted on 0.200", but they were archaic in almost every other aspect of board design as well. Jay DeKing Designer-at-large [log in to unmask] --------- Forwarded message ---------- From: "McGlaughlin, Jeffrey A" <[log in to unmask]> Our standard edge spacing is 0.025"[0.64mm] for copper features and 0.050" [1.27mm] for component bodies. We often drop down to the 0.025"[0.64mm] for both for dense small boards. Our standard was suggested by our fabricator for best yield of routed boards. Jeffrey A. McGlaughlin PCB Designer Battelle Memorial Institute Columbus Ohio [log in to unmask] -----Original Message----- From: Hawes, Adam [SMTP:[log in to unmask]] What do you guys use as a std,rule of thumb package keepin from the edge of a PCB. We are using 1.5mm as standard but I have (the usual story) a small PCB with alot of components to get on! Any feedback from other designers and fabricators would be greatly appreciated.
