Current carrying capacity of a via
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 ... 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.
