    Abstract: An enclosure for holding a printed circuit board includes a housing portion of metal containing at least about 90% magnesium and formed by a semi-solid metal casting process of thixomolding, and including a wall defining an opening to form a spring arm including a tabular portion and a contact pad. The spring arm may be deflected from the wall to provide a contact pressure biasing the first contact pad in physical and electrical contact with the printed circuit board and to provide an electrical grounding connection therebetween. Alternative embodiments are also provided with the spring arm transverse to the wall and with a two spring arms on opposite sides of the printed circuit board. A method of forming a housing portion of an enclosure for holding a printed circuit board is also provided, and which includes steps of thixomolding magnesium to form the housing portion including a spring arm.

    Abstract: A display cluster having an active state and an inactive state includes a front cover with an outer surface facing outwardly toward a viewer and an inner surface opposite the outer surface. An active display region with a display screen to generate an image and a first backlight may be surrounded by a peripheral region including a second backlight. One or more of the backlights may illuminate with the display cluster in the active state. A partial mirror may be disposed on the inner surface of the front cover to allow the display light from the active display region to pass outwardly therethrough and to block incident light from passing therethrough. The partial mirror may prevent reflections from one or more structures located therebeyond, away from the viewer, and may thereby present a uniform appearance between the active display region and the peripheral region with the display cluster in the inactive state.

    Abstract: An enclosure for holding a printed circuit board includes a housing portion of metal containing at least about 90% magnesium and formed by a semi-solid metal casting process of thixomolding, and including first and second housing portions each including a closed end and an open end with a plurality of teeth where the first and second portions join together in a clamshell arrangement to define an enclosed space for holding the printed circuit board. The teeth of the first housing portion may be aligned to overlap and to engage corresponding ones of the teeth of the second housing portion in physical and electrical contact for blocking electromagnetic interference (EMI) with the housing portions closed together. A method of forming a housing portion of an enclosure for holding a printed circuit board is also provided, and which includes steps of thixomolding magnesium to form the housing portion with integrally-formed teeth.
