Current carrying capacity of a via

WebMathematically speaking, the capability of trace to carry current is directly proportional to the cross sectional area of trace and temperature rise. As can be seen from the table below, that under the temperature conditions … WebMay 22, 2016 · Generally I don't recommend going below an 8 mil drill. A microvia is a via that is less than 6 mil in diameter, and will cost you quite a bit more. Physical size (beyond the 6 mil "microvia" limit) really isn't that important unless you need to consider current-carrying capability or controlled-impedance.

WebInternal traces : I = 0.024 x dT0.44 x A0.725. External traces: I = 0.048 x dT0.44 x A0.725. Where I is maximum current in Amps, k is a constant, dT is temperature rise above ambient in °C, & A is cross sectional area of trace mils². The trace width can then be calculated by re-arranging this formula to determine the cross-sectional area that ...
