When to use this calculator
Use it during routing to estimate whether your copper width is in the right range before stackup and DFM review.
Review resistance, voltage drop, and power loss when you need to understand electrical impact beyond width only.
Use the result as a conversation starter with fabrication or assembly engineers when planning copper weight and routing strategy.

Veelgestelde Vragen
Wat is de IPC-2221 norm?
IPC-2221 is de Algemene Norm voor Printplaatontwerp. Het biedt de formules die worden gebruikt om de relatie tussen de stroomvoerende capaciteit van het koperspoor, temperatuurstijging en spoorgeometrie te berekenen.
Waarom is spoorbreedte belangrijk?
Een juiste spoorbreedte zorgt ervoor dat de PCB de vereiste stroom aankan zonder oververhitting, wat zou kunnen leiden tot defecten of schade aan de plaat.
Can I use this calculator as the final manufacturing value?
Use it as an engineering estimate, not a final fabrication rule. Finished copper thickness, etching tolerance, stackup details, and thermal environment can change the real requirement, so final values should be reviewed with your PCB manufacturer.
Need help turning this estimate into a manufacturable PCB?
If you are balancing copper weight, current capacity, voltage drop, and DFM constraints, our team can review your stackup, routing assumptions, and fabrication targets before production.
