Hi,
I am trying to find out what (if any) standards exist to define what the minimum gap between a track on a pcb and the routed edge.
The boards will usually be multilayer, 10-16 layers and 1.6mm, the boards will be coated in soldermask, and conformal coating can be done but tends to hinder diag, so I'd rather avoid it.
If anyone knows of any aerospace standards relating to this detils (trace to edge),and if the definition varies for inners and power/groundplanes, please can you pass on the details.
Thanks Steve Bull
