PCB Guard

Offline PCB design calculator: Trace, Via, Diff-Pair, Clearance. IPC standards based, provably accurate.

PCB Guard Professional PCB design calculator. Trace width, Via capacity, Differential pairs, and DC Loss analysis. 100% Offline & Secure. Design Robust PCBs with Confidence – 100% Offline & Secure PCB Guard is the essential companion for electronics engineers and PCB designers who demand accuracy, security, and speed. Unlike web-based tools that require an internet connection and potentially expose your design parameters to external servers, PCB Guard runs entirely within your browser without sending a single byte of data. Stop guessing trace widths or relying on outdated "rules of thumb." PCB Guard uses physics-based formulas and industry standards (IPC & IEC) to provide provable, engineering-grade calculations directly in your workflow. Why You Should Install PCB Guard: • 100% Offline & Private: Designed for secure environments. No tracking, no analytics, no remote servers. Your IP remains yours. • Physics-Based Accuracy: Calculations are derived from IPC-2152, IPC-2221B, and IEC standards for maximum reliability. • All-in-One Utility: Five critical design modules in a single, lightweight extension. Key Features: 1) Trace Width Calculator (IPC-2152) Calculate the minimum required trace width for a given current and temperature rise. Supports internal/external layers and custom copper thickness. 2) Via Current & Sizing Determine the maximum current capacity of your vias. Includes checks for aspect ratio manufacturability, thermal limits, and recommendations for parallel vias. 3) Differential Pair Impedance Design high-speed microstrips with precision. Calculates Differential Impedance (Zdiff), Single-ended Impedance (Z0), and Coupling Factor based on your stackup. 4) High Voltage Clearance (IEC-60664-1) Ensure safety compliance for high-voltage designs. Calculates minimum Clearance and Creepage distances based on peak voltage, pollution degree, and coating type. 5) DC Loss Analysis Quickly estimate DC Resistance (mΩ), Voltage Drop (mV), and Power Loss (mW) for traces to ensure power integrity. Additional Highlights: • Global Unit Support: Seamlessly switch between Metric (mm) and Imperial (mil) units instantly. • Modern UI: Clean, responsive interface with Dark/Light mode support. • Live Diagrams: Dynamic SVG diagrams visualize your parameters in real-time. • Multi-Language: Interface available in English and Turkish. Perfect for: Embedded Systems Engineers, PCB Layout Artists, Hardware Startups, and Students. No ads. No hidden permissions. Just pure engineering utility.
