Copper Thickness

[Daniel "yOPERO" Garrido]

I think the information below is very important to calculate how deep the spindle should go on the z axis(either one or many passes) , in my cases I have  0.5 oz boards meaning the optimal depth should be 0.0175mm.

The thickness of the copper layer on the PCB affects the behaviour of the circuit. PCB copper thickness is usually measured in ounces per square foot, or frequently, just ounces. It can also be given in mm, inches or mils. The measurements for commonly used thickness are given below.

oz/ft²	mm	in	mil
0.5	0.0175	0.0007	0.7
0.75	0.0255	0.0010	1.0
1	0.035	0.0014	1.4
2	0.071	0.0028	2.8
3	0.105	0.0042	4.2
