Fellow TechNetters: I am requesting clarification on the above stated document section 6.3 Electrical Clearance. The minimum spacing between conductors, between conductive patterns, layer to layer conductive spaces (z=axis), and between conductive materials (such as conductive markings or mounting hardware) and conductors shall be in accordance with Table 6-1, and defined on the master drawing"." Does this implies that the spacing is also true in the vertical, z=axis, direction as measured in a typical cross section.
