Unlock New Capabilities

• From Guesswork to Precision: If you've been relying on digital calipers for every single measurement, this ruler speeds up your workflow significantly for "quick-check" tasks.
• The Design Upgrade: Visualizing a 20 mil vs 50 mil trace on screen is abstract. Probots Lab Verified data shows that having a physical reference helps junior designers make better decisions regarding current capacity and physical routing constraints.

      Virtual Technician: Usage & Safety

• Electrical Safety: Although made of non-conductive FR4, the metal markings (gold/copper) are conductive. Do not place the ruler across live circuits or powered PCBs to measure voltage gaps, as this may cause a short circuit.
• Cleaning: Clean with Isopropyl Alcohol (IPA) to remove flux residue or grime; the silkscreen is solvent-resistant.

Frequently Asked Questions (FAQ)

• Q: Is the scale printed or etched?
  A: The markings are etched into the copper layer and plated, or high-quality silk-screened, ensuring they don't rub off like printed plastic rulers.
• Q: Can I use this as a straight edge for cutting?
  A: Yes, the FR4 fiberglass material is extremely hard and resistant to knife slips, making it an excellent cutting edge for tape or paper.
• Q: Does it include BGA footprints?
  A: It typically focuses on leaded and perimeter-leaded packages (QFP/SOP) and passives, as BGA verification usually requires optical inspection.
• Q: What is the smallest SMD size shown?
  A: It usually references down to 0201 or 0402 sizes, which are the standard limits for manual soldering verification.
• Q: Is the ruler flexible?
  A: No, at 1.6mm thickness, it is rigid and flat, similar to a standard motherboard.
