1. Calculate trace current-carrying capacity To calculate the current-carrying capacity of a trace, you can use the formula fromIPC-2221, which considers factors like temperature rise, cross-sectional area, and conductor thickness. I = (K) (𝝙T𝜷1) (A𝜷2) Where, I is the current in...
Ampacity, also known as current carrying capacity, is the maximum current a microvia can carry without exceeding its temperature rating. Since microvias PCBs conduct current, they will, as a consequence of Ohm’s law, generate heat that will increase the temperature of the components and surroundin...
