Many designs require specific copper thicknesses to accommodate the current requirements of the design. Sunstone offers a variety of copper weights to allow you to meet your design requirements.
Copper Weight is defined as the weight (in ounces) of copper present in one square foot of area. This parameter indicates the overall thickness of copper on the layer.
Sunstone utilizes the following copper weights for PCB fabrication (pre-plate). Weights measured in oz/ft2. The appropriate copper weight can be selected to fit the design requirement.
