PCB trace width calculator

Calculates the width of a PCB trace at a given current

Example 1: Must calculate the PCB track width for a current of 1.6A in outer layer of a standard 1 oz copper PCBView example

Fill all the values of the following
  • Copper thickness - Copper thickness of the PCB surface (typically 35 micrometers)
  • Trace current - Current of the trace on PCB
  • Temperature rise - Allowable temperature rise on trace (typically 10 degrees)
