Abstract

The disclosed mercury probe has one or more mercury reservoirs and one or more passages extending from the reservoir(s) to an aperture plate for engaging a test wafer. Dross that tends to form at the wafer-contact end of the mercury passage(s) is removed by returning all of the mercury in the passage(s) into the reservoir, where the dross is captured. Means is provided to introduce electrical insulation between the reservoir(s) and the aperture(s) of the aperture plate, for disconnecting the mercury probe segment(s) of the mercury from the reservoir(s) and, where there are plural mercury probe segments, for disconnecting them from each other and from their reservoir(s).
