The detail units for double-sided PCB board and other PCB industry commonly use ounces (oz) for copper foil thickness, but why is oz a unit of thickness when it is clearly a unit of weight? Because PCB substrate copper foil specifications are defined by the number of ounces (oz) of copper per square foot (ft²) of area. Since the heavier the copper on a fixed area, the thicker the copper foil will be, and the weight of the copper foil is proportional to the thickness, the weight of the copper foil in ounces (oz) is converted to thickness in mil.
The following units are commonly used for PCBs
