Signatone Probe Stations
Signatone offers a wide array of probe stations that can accept the Mercury Hot / Cold Chuck systems. Signatone CheckMate probe stations can incorporate Signatone’s local chamber that provides a dry and shielded environment directly around the wafer chuck area, eliminating the need to purge the volume of a large dark box.
