FOUR-LINE ELECTRICAL IMPEDANCE PROBE

摘要

A probe is configured for measuring an electrical impedance of a workpiece using external testing equipment. The probe includes a non-conducting base and an array of at least four spaced-apart line conductors. The at least four spaced-apart line conductors are disposed generally in parallel to each other along their lengths on a surface of the non-conducting base and are electrically connected to a corresponding array of at least four terminals on the non-conducting base. The non-conducting base is configured to be placed over a surface of the workpiece so that the at least four spaced-apart line conductors contact the surface of the workpiece and the at least four terminals are configured to be connected the external testing equipment.
