CHANDLER, AZ –Three Rogers Corp. authors received a DesignCon Paper Award for work on issues related to the effects of conductor surface roughness on PCB performance.

The paper, “Effect of Conductor Profile on the Insertion Loss, Phase Constant, and Dispersion in Thin High-Frequency Transmission Lines,” focuses on conductor surface roughness and its effects on conductor loss and effective dielectric constant. It included important findings such as demonstrating that the actual increase in conductor loss can be substantially larger than that predicted by the two most widely used roughness factor correction models, and unexpectedly can impact effective dielectric constant. In particular, conductor roughness can increase the effective dielectric constant in thin circuitry by up to 15%, and increase dispersion.

The paper was coauthored by Allen F. Horn III, John Reynolds, and Patricia LaFrance of Rogers, and James Rautio, president of Sonnet Software.

The DesignCon Paper Award is based on the quality, relevance, impact and originality of the written paper, as well as the oral presentation.
