Radio-frequency solder film surface resistance measurement

摘要

This paper deals with thin solder film measurement using high frequency resonator. Measurement of surface resistance of a conductor that consists of a layer of solder that is applied to the conductive material was done on high frequency, in the range of 500–5000 MHz. This frequency range is chosen because the skin effect concentrates the current flow in a conductor in its surface layer. The RF resistance is critically determined by the properties of a few micrometer thick layer.
