Calculators

Calculators for board designers

Four small calculators for the numbers that come up while you draw a board. They run in your browser: nothing you type is sent anywhere.

  • Track width for a current

    Track width for a current: width, resistance and voltage drop, from IPC-2221.

  • Via current

    Via current: what one plated via carries, and how many you need.

  • Impedance estimate

    Impedance estimate: microstrip, stripline and differential microstrip, from IPC-2141.

  • Panel estimate

    Panel estimate: how many boards fit on a panel, in both orientations.

These are estimates from published formulas. They say nothing about what the factory can make; the capabilities page and the engineer who confirms your order do.
