20cm PCB Reference Ruler Multi Functional Engineering Scale

The 20cm Multifunctional PCB Reference Ruler is an indispensable, pocket-sized tool designed specifically for hardware engineers, electronics hobbyists, makers, and students. Fabricated from high-quality FR4 printed circuit board material with a sleek matte black finish and immersion gold (ENIG) plating, this ruler is both a durable measuring instrument and a comprehensive quick-reference guide for PCB layout design.

Whether you are designing boards in Altium, KiCad, or Eagle, or assembling prototype circuits in the lab, this engineering ruler helps you visually verify component sizes, trace widths, and pin pitches before sending your designs to production. It features a standard metric scale, a 180-degree protractor, and precise physical representations of common surface-mount technology (SMT) footprints, making it the ultimate desktop companion for any electronics developer.

Features:

• SMD Footprint Reference: Includes precise layouts for SOT23, SOT223, SOT25, TO252, SMA, SMB, SMC, and DPAK packages.
• Trace Width Gauge: Features physical trace width references from 10mil up to 80mil to help estimate current-carrying capacity and clearances.
• Pin Pitch Measurement: Quick-reference guides for common pitches including 0.5mm, 0.635mm, 0.65mm, 0.8mm, 1.0mm, 1.27mm, 2.0mm, and 2.54mm.
• Drill Hole Diameter Guide: Integrated circular gauges to quickly measure wire and drill hole sizes in both mil and metric units.
• 180-Degree Protractor: Built-in angle measurement tool for mechanical alignment and drawing.
• Premium FR4 Construction: Made from standard PCB substrate with gold-plated markings for high wear resistance and professional aesthetics.
