3-12A Metallic Foil Task Group
This task group is responsible for maintaining IPC-4562, "Metal Foil for Printed Wiring Applications," and is working on a new test method (TM 2.2.22) that measures the surface roughness of metal foils.
The test method is measuring the roughness using non-contact techniques, providing substantially better precision and accuracy than has been available when the contact method involving a stylus is used.
The surface roughness of copper foil is important to accurately know, especially when high frequencies are involved so as to better predict signal distortion or loss.
