Demanding Technology

Control of Copper surface roughness in Printed Circuit Boards (PCB) is becoming more significant in multi-GHz designs for high speed PCBs.

Challenging Technology

Skin Effect loss and surface roughness in copper conductors on PCB boards is a growing challenge for PCB designers.

Innovative Solutions

The roughness profile of an inner-layer trace is influenced not only by the grade of copper foil on the laminate core material, but also by the nature of the copper oxide and or alternative-oxide inner-layer treatment process.
