NettetThis tool is used to calculate the nominal equivalent values of wire sizes such as American Wire Gauge [AWG], Square Millimeter Area [mm 2 ], Circular Mil Area [CMA], and more. Just put in a known measurement or value and all of the equivalent values will be automatically calculated and displayed. NettetFor signals or probing, the smallest wire that I would ever use is about 30AWG. With Kevlar insulation, it can be usably solid. So I make any traces I might need to probe accessible with 0.015" vias, plus a margin for pad size. But if I have room it's better to use a hole big enough for a 0.100" connector, ie 0.040".
