Abstract: The invention provides coating units, heat-treating units, and a first main transport mechanism for transporting substrates to each of these treating units. The substrates are transferred from the first main transport mechanism to a second main transport mechanism through a receiver.

Abstract: Method and apparatus for applying a thermal conductive medium (TCM) to the inside of a disposable sheath. A uniform amount of TCM is applied in an automated manner to the conductive portion of a disposable sheath to increase conductivity. Application is by way of a rotating tip having a plurality of nozzles through which TCM is pumped under control of a timing circuit.

TCM application is avoided at portions of the sheath where thermal conductivity is not desired and at the tip of the sheath which will be coated by TCM as a result of probe insertion into the sheath. By automating the TCM application process, TCM can be applied in precise amounts and in a uniform manner without accidentally coating areas of the sheath where TCM is not desired. In addition the process can be conducted in far less time than is required to manually apply TCM.
