Kalkulator Lebar Jejak PCB
Hitung lebar jejak optimal sesuai standar IPC-2221
Kalkulator Lebar Jejak PCB
Use IPC-2221 based estimation to size copper trace width and review the electrical impact on resistance, voltage drop, and power loss.
Sesuai 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.

Pertanyaan yang Sering Diajukan
Apa itu standar IPC-2221?
IPC-2221 adalah Standar Umum tentang Desain Papan Cetak. Ini menyediakan rumus yang digunakan untuk menghitung hubungan antara kapasitas pembawa arus jejak tembaga, kenaikan suhu, dan geometri jejak.
Mengapa lebar jejak penting?
Lebar jejak yang tepat memastikan PCB dapat menangani arus yang dibutuhkan tanpa kepanasan, yang dapat menyebabkan kegagalan atau kerusakan papan.
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.
