28 PCB007 MAGAZINE I SEPTEMBER 2024 tions, it is important to require Dk values that are consistent across all relevant frequency, temperature, and humidity conditions. Conductor losses. As operating frequen- cies increase, conductor losses begin to dom- inate system performance, creating challenges and gaps for copper foil manufacturers. Cop- per foil manufacturers must develop grades with extremely low surface profiles, controlled grain sizes, and treatments. ey need to develop bonding agents that provide not just the required electrical performance, but also maintain the reliability of the bond between the foil and the dielectric.
