How thick is copper on a circuit board?
1.37 mils
The most common unit of measure for the copper thickness on a printed circuit board is ounces (oz). But how thick is that? It’s the resulting thickness when 1 oz of copper is pressed flat and spread evenly over a one square foot area. This equals 1.37 mils (1.37 thousandths of an inch).
What is the standard thickness of a copper layer on a PCB?
roughly 1.4 mm to 2.8 mm
PCB Copper Thickness: The standards copper thickness is roughly 1.4 mm to 2.8 mm (for internal layers) and 2-3 oz. (including the external layers). The thickness is adjusted according to your requirements. Keep in mind that increased copper means higher price and challenging processing.
How do you determine the thickness of copper?
Great question! If 1oz (28.35 grams) of copper is flattened to evenly cover 1 square foot of surface area (0.093 square meter), the resulting thickness will be 1.37mils (0.0348mm)….Copper Thickness Conversion Chart.

How many ounces of copper are in a PCB?
1 oz
Most printed circuit boards are constructed with 1 oz copper thickness. In PCB manufacturing, if customers do not offer specific specs, we will assume 1 oz when quoting and building the design.
What is finish copper thickness?
When we consider the layer copper thickness on a PCB we refer to: Start Copper or Base Copper – The copper thickness as received from our suppliers. End Copper or Finished Copper – This is the final thickness of copper on the finished PCB.
What is 2 oz copper PCB?
A 2 oz copper PCB is a printed circuit board whose copper weight per square foot amounts to two ounces. To make this circuit board, copper of two-ounce weight is flattened to form an even surface with square dimensions of one foot. The resulting thickness of this board type is about 2.8 mils or 70 micrometers.
