  • Publication number: 20220007506
    Abstract: A method for manufacturing a wiring board capable of improving adhesion between an underlayer and a seed layer. An electrically conductive underlayer is disposed on the surface of an insulating substrate and a seed layer containing metal is disposed on the surface of the underlayer to prepare a substrate with seed-layer. A diffusion layer in which elements forming the underlayer and seed layer are mutually diffused is formed between the underlayer and the seed layer, by irradiating the seed layer with a laser beam. A metal layer is formed on the surface of the seed layer by disposing a solid electrolyte membrane between an anode and the seed layer as a cathode and applying voltage between the anode and the underlayer. An exposed portion without the seed layer of the underlayer is removed from the insulating substrate.

  • Publication number: 20210410291
    Abstract: A seeded substrate is first prepared. The seeded substrate includes an insulation substrate having a main surface composed of a first region and a second region other than the first region, and a conductive seed layer provided on the first region. Subsequently, a conductive layer is formed on at least the second region to obtain a first treated substrate. An insulation layer is then formed on the first treated substrate. The seed layer is then exposed. A metal layer is then formed on the surface of the seed layer. Here, a voltage is applied between the anode and the seed layer while a solid electrolyte membrane containing a metal ion-containing solution being disposed between the second treated substrate and the anode, and the solid electrolyte membrane and the seed layer being pressed into contact with each other. Thereafter, the insulation layer and the conductive layer are removed.

  • Publication number: 20210392753
    Abstract: The present disclosure provides a method for producing a wiring substrate. A seeded substrate including an insulation substrate, a conductive undercoat layer, and a conductive seed layer provided in a first region, in that order, is first prepared. An insulation layer covering the seed layer and the undercoat layer is then formed. Subsequently, the insulation layer is etched to expose a surface of the seed layer and form a remaining insulation layer covering the undercoat layer in the second region. Subsequently, a voltage is applied between an anode and the seed layer while a solid electrolyte membrane containing a metal ion-containing aqueous solution disposed between the seed layer and the anode and the membrane and the seed layer pressed into contact with each other, thereby a metal layer being formed on the surface of the seed layer. Thereafter, the remaining insulation layer is removed and the undercoat layer is etched.

  • Publication number: 20210204409
    Abstract: A method for manufacturing a wiring board is capable of forming a metal layer included in a wiring layer to have an even thickness. The method includes preparing a conductive first underlayer on a surface of a substrate; a conductive second underlayer on a surface of the first underlayer; and a seed layer on a surface of the second underlayer and containing metal. The method disposes a solid electrolyte membrane between an anode and the seed layer as a cathode; applies voltage between the anode and the first underlayer to form a metal layer on the surface of the seed layer; removes an exposed portion of the second underlayer without the seed layer from the substrate; and removes an exposed portion of the first underlayer without the seed layer from the substrate. The first underlayer is a material having a higher electrical conductivity than that of the second underlayer.

A lance (10) formed by punching the bottom protrudes outwards to be of the same width as a transverse width of the bottom and have two bent portions. One of the bent portions is located at a basal end (11) of the lance, and the other at a middle region (14) of the lance, thereby affording improved rigidity and resiliency to the lance. The bottom (3) has a broadened inner end (17) of the same width as a transverse width of contact body (2), so that the lance is of an improved rigidity and resiliency to be firmly retained in a connector housing not to slip off, even if made smaller in size.
