PCB Trace Width Calcolatore (IPC-2221A)

Calculate minimum PCB trace width for given current + allowed temperature rise. Per IPC-2221A standard. External vs internal layers, copper weight 0.5/1/2/3 oz.

How to use this tool

  1. 1

    Current + temp rise

    Trace current and allowed Δt.

  2. 2

    Copper weight + layer

    1oz/2oz, internal vs external.

  3. 3

    Min trace width

    Per IPC-2221A formula.

Frequently Asked Questions

IPC-2221A formula?
I = k × ΔT^0.44 × A^0.725. External: k = 0.048; internal: k = 0.024. ΔT in °C, A in mil² (cross-section), I in amps. Solved for required area.
Why are internal traces worse?
No air convection — heat trapped. Same trace width carries ~half the current vs external. Internal layers always need ~2× wider for same current.
1oz vs 2oz copper?
1oz = 35 µm thick, 2oz = 70 µm. 2oz roughly halves required width (more cross-section). Costo: 2oz costs ~30% more, used for power-handling boards.
