PCB Sporbreddekalkulator
Beregn optimal sporbredde i henhold til IPC-2221 standarder
PCB Sporbreddekalkulator
Use IPC-2221 based estimation to size copper trace width and review the electrical impact on resistance, voltage drop, and power loss.
IPC-2221 Samsvar
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.

Ofte stilte spørsmål
Hva er IPC-2221 standarden?
IPC-2221 er den generelle standarden for design av trykte kort. Den gir formlene som brukes til å beregne forholdet mellom kobbersporets strømførende kapasitet, temperaturstigning og sporgeometri.
Hvorfor er sporbredde viktig?
Riktig sporbredde sikrer at PCB-en kan håndtere den nødvendige strømmen uten overoppheting, noe som kan føre til feil eller skade på kortet.
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.
