About this app

TraceCalc is a specialized engineering utility designed for professionals and hobbyists working on printed circuit board design. Built upon the industry-standard IPC-2152 laboratory data, this tool provides accurate estimations for trace width requirements based on current load and thermal constraints.
Whether you are designing high-power power supplies or compact logic boards, TraceCalc helps you determine the electrical characteristics of your PCB traces with precision. By using the newer IPC-2152 standard, you get more reliable results than the older IPC-2221 curves.

Key Features:
• Trace Width Calculation: Determine the required width for a specific current (Amperes) and allowed temperature rise (Celsius).
• Dual-Unit Support: View results instantly in both imperial (mil) and metric (mm) units.
• Thermal Management: Support for both internal and external layers to account for different heat dissipation environments.
• Copper Weights: Choose from common copper weights including 0.5 oz, 1.0 oz, 2.0 oz, 3.0 oz, and 4.0 oz.
• Electrical Characteristics: View estimated resistance (Ω/cm) and voltage drop (V/cm) for your calculated traces.
• History Log: Save and review previous calculations to maintain consistency across your project documentation.
• Reference Guide: Access a technical overview of copper thicknesses and professional hardware design tips.
• Data Export: Copy results to your clipboard or share them with colleagues directly from the app.

Professional Standard: TraceCalc utilizes the simplified IPC-2152 charts to provide rapid estimations. This standard is widely recognized as the most accurate method for determining current-carrying capacity in printed board design.

Disclaimer: TraceCalc is intended for estimation purposes only. Critical hardware designs should always be verified with thermal simulation and physical testing.
