Abstract

A new triaxial test fixture has been developed for measuring the transfer impedance of the shield of a board-to-board or backplane connector. A lot of attention has been paid to the design of the outer and inner line of the test cell. As a reference, first transfer impedance measurements were done on a commonly used coaxial cable where a good agreement with literature results was found. Various configurations of the connector shield were further measured and compared, showing a large influence of the omission of side and bottom parts of the connector shields
