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 ...
