Abstract: A device has a housing with a top part that accommodates one or more pressable keys forming the user-interface of the device. Each specific key has a specific keycap. The top part is formed from a harder plastic element and a softer rubber layer in a two-shot injection molding process. The harder plastic element has one or more openings occupied by the softer rubber layer. The harder plastic element has a specific pin positioned in a specific hole of the softer rubber layer. The specific keycap has a bottom face with a specific protruding sleeve configured for engaging with the specific pin. The bottom face of the specific key and an area at a top face of the softer rubber layer have complimentarily shaped profiles configured for accurately orienting the keycap relative to the top part.

Abstract: An assembly (20) for use in a keypad device (10) and a corresponding keypad device (10) are described. The assembly (20) comprises a seamless faceplate (30) with a plurality of key areas protruding outwardly from a surface (32) of the faceplate. The key areas are made of slightly deformable material. The assembly further comprises a plurality of switch elements (e.g., dome switches) (62), which at least partly correspond to the key areas. The switch elements are arranged to contact a corresponding contact point on a circuit arrangement (90) e.g. a PCB, as a result of force on the corresponding key area being applied by a user, wherein after the user stops applying the force, the key area returns to its original position, e.g. due to the corresponding dome switch returning to its original position.

Abstract: An apparatus and method for detecting characteristics of a microelectronic substrate. The microelectronic substrate can have a first surface with first topographical features, such as roughness elements, and a second surface facing opposite from the first surface and having second topographical features, such as protruding conductive structures. In one embodiment, the apparatus can include a support member configured to carry the microelectronic substrate with a first portion of the first surface exposed and a second portion of the second surface exposed. The apparatus can further include a topographical feature detector positioned proximate to support member and aligned with the first portion of the first surface of the microelectronic substrate to detect characteristics, such as a roughness, of the first surface while the microelectronic substrate is carried by the support member.
