Conform IPC-2221
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.

Întrebări Frecvente
Ce este standardul IPC-2221?
IPC-2221 este Standardul Generic privind Proiectarea Plăcilor Imprimate. Acesta oferă formulele utilizate pentru a calcula relația dintre capacitatea de transport a curentului traseului de cupru, creșterea temperaturii și geometria traseului.
De ce este importantă lățimea traseului?
O lățime adecvată a traseului asigură faptul că PCB-ul poate gestiona curentul necesar fără supraîncălzire, ceea ce ar putea duce la defectarea sau deteriorarea plăcii.
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.
