Metal core PCB:Copper Weight in a PCB,Do You Know it?
Copper is one of the most important elements in metal core PCB. Copper Weight or Copper Thickness in a metal core PCB represents the thickness of 1 ounce of copper rolled out over an area of 1 square foot. For example, a PCB that has a copper weight of 1 oz will have a layer of copper that is 1.4 mils in thickness. Copper Weight is measured in ounces per square foot (oz/ft²).
Copper Weight in oz vs Copper Thickness in Mils
Cu Weight |
Thickness in Mils |
1 oz |
1.4 mils |
2 oz |
2.8 mils |
3 oz |
4.2 mils |
4 oz |
5.6 mils |
Why is Copper Weight Important for Printed Circuit Boards?
The current carrying capacity of a PCB depends on the thickness of the copper trace. So metal core PCB's with a higher Copper weight will be able to carry more current.
