    摘要: A method for forming a hole plug in a laminate structure is provided. A laminate structure, is formed, including at least a dielectric layer and a first conductive foil on a first side of the dielectric layer. An unpierced or blind hole is formed in the laminate structure extending toward the first conductive foil from a second side of the dielectric layer and at least partially through the dielectric layer, the hole having a hole depth to hole diameter aspect ratio of less than ten (10) to one (1). In yet another example, the hole aspect ratio may be less than one (1) to one (1). Via fill ink may then be deposited in the hole. The via fill ink is then dried and/or cured to form a hole plug.

    摘要: A wiring board unit includes a connector having a plurality of terminals; and a wiring board on which the connector is mounted. The wiring board includes a first wiring pattern provided on a first wiring layer, a second wiring pattern provided on a second wiring layer at a position shallower than the first wiring layer, a first via formed in a first recess having a first depth, the first via being in contact with the first wiring pattern, and a second via formed in a second recess having a second depth that is smaller than the first depth, the second via being in contact with the second wiring pattern.

    摘要: Copper plating baths containing a leveling agent that is a reaction product of a certain benzimidazole with a certain epoxide-containing compound that deposit copper on the surface of a conductive layer are provided. Such plating baths deposit a copper layer that is substantially planar on a substrate surface across a range of electrolyte concentrations. Methods of depositing copper layers using such copper plating baths are also disclosed.
