Related apparatus and methods are also described.

A wiring board and a method for manufacturing the wiring board in which an initial Cu plated layer is formed by plating so as to cover the surface of a metallized layer and then the initial Cu plated layer is heated to be softened or melted. Copper in the softened or melted initial Cu plated layer enters into open pore portions of the metallized layer. In addition, during the heating, components of the metallized layer and components of the initial Cu plated layer are mutually thermally diffused. Consequently, when solidified later (that is, when the initial Cu plated layer becomes a lower Cu plated layer), the adhesiveness between the metallized layer and the lower Cu plated layer is improved due to, for example, an anchoring effect and a mutual thermal diffusion effect.

A highly-ordered nano-structure array, formed on a substrate, mainly comprises a plurality of highly-ordered nano-structure units. Each of the highly-ordered nano-structure units forms a receiving compartment. One end of the receiving compartment opposite to the substrate has an opening. Each of the highly-ordered nano-structure units comprises at least one thin film layer. A periphery and a bottom of the receiving compartment are defined by an inner surface of a surrounding portion of the at least one thin film layer and a top surface of a bottom portion of the at least one thin film layer, respectively. The at least one thin film layer is made of at least one material selected from the group consisting of: metal, alloy, oxide, nitride, and sulfide.

A part assembly (100), comprising: an aluminium part (101); a magnesium part (102), the magnesium part (102) coated in a first coating (104); a bond (103), the bond (103) securing the aluminium part (101) to the coated magnesium part (114); wherein the aluminium part (101), the coated magnesium part (114) and the bond (103) are subjected to an electrophoresis coating process to coat the aluminium part (101) in a second coating (105). By subjecting the aluminium part (101), the coated magnesium part (114) and the bond (103) to an electrophoresis coating process to coat the aluminium part (101) in a second coating (105) this may provide a simpler manufacturing process.

A joint structure includes: a first same-type metal member; a second same-type metal member that can be mutually welded with the first same-type metal member; and a different-type member that has a penetrating portion, is interposed between the first same-type metal member and the second same-type metal member. In the plate thickness direction of an emission region in which a laser beam is emitted toward the penetrating portion, the plate thickness at the emission region of the first same-type metal member positioned on the side on which the laser beam is emitted is a predetermined thickness corresponding to a first gap. The first same-type metal member and the second same-type metal member are fused and bonded together via the penetrating portion, and the different-type member is compressed and fixed, such that the different-type member is fixed to the first same-type metal member and the second same-type metal member.

A material includes a sheet of metal having a first face and an opposed second face, and a metal grain direction. The first face is textured with a first set of texturing features. Each texturing feature of the first set includes, respectively, a groove cut into the first face and extending along a groove axis, and a barb extending from the groove and away from the first face. The texturing features of the first set are arranged in a plurality of rows, and the groove axes of the texturing features in a given row extend generally parallel to the given row. The rows are generally non-perpendicular to the grain direction.

A window includes a coating layer including a front surface, a rear surface, a first region having a constant distance between the front surface and the rear surface in a thickness direction, and a second region in which a distance between the front surface and the rear surface reduces in a direction away from the first region; and a bezel layer disposed on the rear surface of the coating layer, where the coating layer includes inorganic particles, an acrylate resin and an epoxy resin.
