Professional PCB Trace

https://tracewidthcalculator.com/

Main Features

Trace Width Calculation: Calculate minimum trace width based on current, temperature rise, copper thickness, and layer type
Detailed Analysis: Provide resistance, voltage drop, power loss, and cross-sectional area calculations
Safety Margin Recommendations: Suggest using 20-50% wider traces than calculated minimum
Dual Standard Support: Support for both IPC-2152 (modern standard) and IPC-2221 (traditional standard)
Unit Conversion: Support for both imperial and metric units

Usage Process
