Professional PCB Trace

Share

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

  1. Enter current requirements (Amperes)
  2. Set acceptable temperature rise (10°C for conservative, 20-30°C for standard applications)
  3. Select copper thickness (0.5oz to 3oz)
  4. Choose layer type (external or internal)
  5. Get calculation results and safety margin recommendations
