  • Patent number: 11399426
    Abstract: 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.

  • Patent number: 10641457
    Abstract: A headlight includes light sources, and phase modulation elements that diffract lights incident from the light sources with changeable phase modulation patterns. The lights diffracted by the phase modulation elements are emitted with a low beam light distribution pattern that is a predetermined light distribution pattern based on the phase modulation patterns. A projection region on which zeroth order lights, that are emitted from the phase modulation elements without being diffracted by the phase modulation elements, among the lights incident on the phase modulation elements, are projected is located within a range where a driver's view of a vehicle is obstructed by the vehicle.

  • Publication number: 20190191544
    Abstract: The present invention provides a wiring board having a conductor portion on which mounting is suitably possible and a method for manufacturing the wiring board. Since 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, and therefore mountability is improved.
