Abstract:
A mobile plating system for performing a plating process, the mobile plating system comprising:a mobile storage volume; a vacuum chamber positioned in the mobile storage volume the vacuum chamber having an internal volume large enough to contain at least one reactor vessel head stud; an external vacuum pump operable to be positioned within the mobile storage volume when the mobile plating system is in transit, and to operate external the mobile storage volume when the mobile plating system is stationary and in operation, the external vacuum pump operable to couple with the vacuum chamber through a flexible piping segment to assist with producing a desired pressure in the vacuum chamber when the mobile plating system is stationary and in operation; an internal vacuum pump operable to couple with the vacuum chamber to assist with producing the desired pressure in the vacuum chamber; a control module operable to control the external vacuum pump; a platform operable to be positioned within the vacuum chamber and to support a substrate to be plated; a filament operable to hold a depositant within the vacuum chamber in relation to the platform; and an associated equipment that includes: a dc power supply operable to generate a desired voltage at the substrate, an rf transmitter operable to generate an rf signal at a desired power level at the substrate, and a filament power control module operable to generate a current at a desired level at the filament.
