Losses caused by roughness of metallization in printed-circuit boards
IEEE TRANSACTIONS ON ADVANCED PACKAGING(2005)
摘要
In this paper the effect of metal roughness on the total loss, the extracted tan delta, and signal integrity of typical interconnections found in printed-circuit boards is extracted from measurements on three different materials. The differing characteristics of the roughened metal cross sections are highlighted, and a simplified, practical, two-dimensional, causal, broadband modeling methodology is shown.
