• Fiberglass-epoxy type boards (G-10/FR-4) have a dielectric constant of around 4.2 to 4.8
• Teflon boards have a dielectric constant of around 2.55
• The dielectric constant varies with board manufacture and frequency, that's why it's called a constant.
• One ounce weight corresponds to a copper thickness of 0.0014 inches (0.04 mm)
• Two ounce weight corresponds to a copper thickness of 0.0028 inches (0.08 mm)
• Common 1/16 inch board has a substrate thickness of 0.059 inches (1.5 mm)
• Common 1/32 inch board has a substrate thickness of 0.028 inches (0.71 mm)
