## What is the thickness of 1 oz copper?

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 thickness of 2 ounce copper?

2.8 mils
2 oz copper (70µm thick or 2.8 mils) — Standard internal layer copper thickness for internal layers on 3 oz finished copper selection. This is the standard starting copper thickness on the external layers for PCBs with the 3 oz finished copper weight selection.

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.

### What is finished copper thickness?

According to the IPC-A-600J-Class 2 Standards an 18 µm Start Copper must have a minimum End Copper of 33.4 µm, here we state +/-35 µm as “Our Nominal End Copper Thickness” where the “+/-” means approximately and is based on our manufacturing experience but has a guaranteed minimum thickness of 33.4 µm.
