Assuming agressive design rules what is the minimum distance I can get away with between the board edge and a SMT pad and between the board edge and a plated mounting hole ??? (The board is only 1"x2" and the mounting holes are 80 mil dia, 125 mil

Stuart, My suggestion is a DFM meeting (most of the process people dream about a meeting like this, and luckily, I've been to a few) with: - project manager (if there's one) - customer service rep (annual volume, lot size, product life) - smt proce

Would this dimension be the same if the board is panelized and the board has break aways? Nancy

Bingo!!! By panelizing and adding breakaway rails (as Nancy says), Stuart can pour copper up to his board fab's tolerance from the board edge. Traditionally, he just wants to make sure no copper shows on the edge of the board. Then again, it's his

Close but not to close, would have to be the spec. Or depends on your separating technology. Prerouted boards on a panel, you could go right up to the edge. V-grove you will need more distance, maybe 2mm's or more. The distance from the panel edge to

There's no easy answer. It depends on: * Thickness and size of the PCB in the array. * Means of separation. * Type of component. SMT components are more sensitive to the forces that need to be applied to separate the PCB. * Type SMT device. Ceram
