US Patent 7663384 Method and apparatus for measuring metallic area-specific resistance

A simple method and apparatus for measuring the low area specific resistance of a metal plate, particularly in high temperature (<962° C.) environment, are provided. The metal plate, which may include a coating, is used in high temperature environment for electric conduction. Silver paste is applied on the metal surface. Paste sintering processes to minimize contact resistance are described. These sintering processes cause negligible change to the original metal condition, thus accurate and precise area specific resistivity of the metal plate can be obtained.
