A multiple-ratio drive transmission comprises first and second spaced disc systems, each system of which is composed of three separate discs: a retention disc located at an outermost side; a pin receiving disc located at an innermost side; and, a pin holding disc sandwiched between. The arrangement includes a source of Ultraviolet light, as well as one or more fiber-optic filaments for transmitting the UV light for output at one or more locations on the hand-held electronic device. The motor assembly also includes one or more asynchronous motors, each asynchronous motor controlling the surface speed and the torque of one of the intermediate rolls. A substrate spin rinse dry chamber in communication with the central substrate transfer enclosure is provided and is accessible to the at least one substrate transfer robot, and an annealing chamber in communication with the central substrate transfer enclosure is provided and is accessible to the at least one substrate transfer robot. The pillar is press-fit into an opening in the ground plane, and the ground plane is electrically connected to the pad. A series of patterned holes are laser ablated onto an upper surface of the extrusion.
