    Abstract: The present disclosure describes thermal management devices. In one example, a thermal management device can include a processing unit, a thermal grease layer directly contacting the processing unit, and a heat pipe. The heat pipe can include a heat pipe interior volume having a working fluid disposed therein, a first exterior surface directly contacting the thermal grease layer, a second exterior surface opposite from the first exterior surface, and side exterior surfaces connecting the first exterior surface and the second exterior surface. The thermal management device can also include a device cover spaced from the second exterior surface of the heat pipe by a distance from greater than 1 mm to about 5 mm, and a bracket having a clamping portion that holds the heat pipe by the side exterior surfaces of the heat pipe. The clamping portion does not extend past the first exterior surface of the heat pipe.

    Abstract: A panel for a touch screen of an electronic device is described. The panel comprises a substrate having a central area for operating the touch screen and a border area at an edge of the central area. The border area comprises a decorative image on the substrate and an outer surface coating overlying the decorative image. The decorative image comprises a non-conductive metallic coating. The outer surface coating comprises a non-conductive, printed layer. A method for manufacturing the panel and an electronic device comprising a touch screen having the panel are also described.

    Abstract: The present disclosure is drawn to covers for electronic devices. In one example, a cover for an electronic device can include an aluminum or aluminum alloy cover frame having an opening. A magnesium or magnesium alloy cover panel supported by the aluminum or aluminum alloy cover frame within or over the opening. A protective coating can be over a surface of the aluminum or aluminum alloy cover frame and a surface of the magnesium or magnesium alloy cover panel. A chamfered edge can include a chamfer at an edge of the aluminum or aluminum alloy cover frame. The chamfer can expose the aluminum or aluminum alloy cover frame beneath the protective coating, and the chamfer at the same time does not expose the magnesium or magnesium alloy cover panel.

    Abstract: The present disclosure is drawn to printed foam panels for electronic devices. In one example, a printed foam panel for an electronic device can include a substrate, a primer layer on the substrate, a foam pattern on the primer layer, and a clear coating layer on the foam pattern. The foam pattern can cover a first portion of the substrate and leave a second portion uncovered. The foam pattern can include a printed pattern of a foaming composition including a photoacid generator compound and a metal carbonate activated to form the foam pattern.
