PCB board copper thickness and design guidelines
PCB board copper thicknesses are generally classified as 1oz (35μm), 2oz (70μm) and 3oz (105μm). Of course, the copper thickness depends on the type of board you are making. Copper thickness for switching power supplies with high currents is 2oz. for signal transmission, usually, 1oz is sufficient. Normal double-sided boards are 1oz. Multilayer circuit boards […]
