  • Patent number: 11591257
    Abstract: A multi-layer and method of making the same are provided. The multi-layer, such as a sensor, can include a high strength glass overlay and a lamination layer on a substrate layer. The overlay can be less than 250 micrometers thick and have at least one tempered surface incorporating a surface compression layer of at least 5 micrometers deep and a surface compressive stress of at least 200 MPa. The overlay can exhibit a puncture factor of at least 3000 N/?m2 at B10 (10th percentile of the probability distribution of failure) in a multi-layer structure, an apparent thickness of less than 0.014 mm, and a pencil hardness greater than 6H. The method can include ion-exchange tempering at least one major surface of a glass sheet, light etching the major surface to remove flaws and laminating the glass sheet on the tempered and lightly etched major surface to a substrate layer.

  • Publication number: 20210125869
    Abstract: Embodiments of the disclosure relate to a method for creating a strip of electronic components. In the method, a ribbon of ceramic substrate is provided. The ceramic substrate defines a thickness of no more than 200 ?m between a first outer surface and a second outer surface opposite of the first outer surface. A conductive layer is applied to at least one of the first outer surface or the second outer surface of the ceramic substrate. The ceramic substrate is then singulated into individual slabs, and the individual slabs are laminated to a strip of polymeric carrier. The polymeric carrier has a flexural rigidity less than the flexural rigidity of the ceramic substrate. Additionally, embodiments of a roll of electronic components are provided.

  • Patent number: 9573843
    Abstract: Described herein are various polymer-covered glass and glass-ceramic articles that exhibit improved adhesion between the polymer and the glass or glass-ceramic, along with methods for their manufacture and use. The improved articles generally include a glass or glass-ceramic substrate, a surface-roughened coating disposed on at least a portion of an edge of the glass or glass-ceramic substrate, and a polymer covering disposed on at least a portion of the surface-roughened coating. The surface-roughened coatings beneficially allow the polymer coverings to adhere better to the edge surfaces of the glass or glass-ceramic substrates relative to similar or identical articles that lack the surface-roughened coating.

  • Publication number: 20150261261
    Abstract: A cover assembly for an electronic device includes a sensor element embedded in the opening of a substrate such that the first side of the sensor element is flush with the first surface of the substrate. This allows for conductive elements in the sensor element to be present at a surface of the cover assembly. The conductive elements are inside via holes. A sensor substrate with the via holes can be formed using a redraw process or a laser damage and etch process.
