Conductor thickness is the thickness of the copper layer on a printed circuit board. It is a crucial parameter that directly impacts the electrical conductivity and current-carrying capacity of the traces on the board. The conductor thickness is typically specified in ounces per square foot (oz/ft²), with common values including 0.5 oz/ft² (17.5µm), 1 oz/ft² (35µm), 2 oz/ft² (70µm), and so on.
