30cm PCB Reference Ruler Multi Functional Engineering Scale

The 30cm PCB Reference Ruler is an indispensable, multi-functional tool designed specifically for hardware engineers, electronics hobbyists, makers, and engineering students. Crafted from high-quality FR-4 fiberglass material with gold-plated copper accents, this ruler serves as a highly durable physical measuring scale and a quick-reference guide for PCB design layouts. It eliminates the guesswork during prototyping by providing real-world physical references directly on your workbench.

This engineering reference ruler is packed with essential design guides, including standard SMD component footprints (such as SOT, SOP, QFP, and passive sizes like 0603, 0805, 1206), trace width gauges in both mils and millimeters, a 180-degree protractor, and AWG wire size drill holes. It is the perfect companion for verifying component spacing and trace clearances when designing circuits in Altium, KiCad, Eagle, or EasyEDA.

Features:

• Premium FR-4 Construction: Made from standard printed circuit board material with a sleek matte black finish and gold-plated copper markings for lifetime durability.
• SMD Footprint Reference: Features common package layouts including SOT23, SOT89, SOP16, TQFP64, and passive chip sizes (0402, 0603, 0805, 1206, 1812).
• Trace Width Gauge: Easily verify trace widths with precise line thickness guides marked in both millimeters and mils.
• Integrated Protractor: Includes a 180-degree protractor on the end for quick angle measurements and layout planning.
• Drill Hole & Wire Guide: Built-in circular aperture gauges to quickly measure wire diameters, screw sizes, and drill hole diameters.
• Dual-Unit Scale: Features highly accurate metric (mm/cm) and imperial (inch) scales etched directly into the board.
