    Abstract: A method for manufacturing a probe test structure for microcircuits utilizes a multiple coating method in conjunction with a novel double-cell electroplating apparatus having a relatively high-resistance ion path between the cells. Photoresist is applied to both sides of a copper foil, copper posts are electroformed onto selected areas of one side of the foil through image hole patterns, the remaining photoresist is stripped away, polyimide prepreg is laminated to the post side of the foil, the copper posts are exposed by sanding, photoresist is reapplied to both sides of the sanded remainder, additional copper is electroformed on each post through image hole patterns in the post side of the photoresist, the foil on the side opposite the posts is chemically milled to provide leads integral with each post using appropriate masking techniques and, finally, all of the remaining photoresist is removed to leave the desired test probe set. In a second embodiment, nickel plating is added over the copper to achieve selective etching, permitting processing of both sides of the copper foil simultaneously.

    Abstract: An interconnection element and method for making same is disclosed. The interconnection element may include a plurality of metal conductors, a plurality of solid metal bumps and a low melting point (LMP) metal layer. The solid metal bumps overly and project in a first direction away from respective ones of the conductors. Each bump has at least one edge bounding the bump in at least a second direction transverse to the first direction. The low melting point (LMP) metal layer has a first face joined to the respective ones of the conductors and bounded in the second direction by at least one edge and a second face joined to the bumps. The edges of the bumps and the LMP layer are aligned in the first direction, and the LMP metal layer has a melting temperature substantially lower than the conductors.

    Abstract: To provide a printed wiring board and a method for manufacturing the printed wiring board in which circuit widths of a signal transmission circuit and a power supply circuit or the like, which conventionally require to have greatly different circuit widths, are close to each other as much as possible and substantial miniaturization can be achieved. In order to achieve this object, a printed wiring board obtained by etching a metal-clad laminate including a conductive layer and an insulating layer is employed, in which a first circuit and a second circuit having different thicknesses formed in a same reference plane coexist. In addition, it is characterized in that a thicker circuit of the first circuit or the second circuit has a clad-like configuration in which three layers of a first copper layer/a different kind of metal layer/a second copper layer are sequentially stacked. Further, a manufacture of the printed wiring board is characterized in that a clad composite material in which three layers of a first copper layer/a different kind of metal layer/a second copper layer are sequentially stacked is a start material, and selective etching characteristic between the different kind of metal layer and the copper layer is effectively utilized.
