Today, according to the IPC-4562A, we will learn about the relation between the weight and thickness of Copper foil.
In the production and manufacturing of PCB copper foil, the weight and thickness of the copper foil are two critical parameters.
The weight of copper foil is commonly measured in ounces (oz), with 1 ounce equaling 28.3 grams. Common weights include 1/2 oz, 3/4 oz, 1 oz, and 2 oz. For instance, a copper foil with a weight of 1 oz/square foot is equivalent to 305 grams/square meter in metric units. By converting through the density of copper (8.93 g/cm³), this corresponds to approximately 34.3 micrometers in thickness. The term "1/1" copper foil refers to a copper foil that weighs 1 ounce spread evenly over an area of 1 square foot. The table in the cover image further details the relationship between the weight and thickness of copper foil.
