Thus, the PCB panel has multiple through-holes that can then be plated simultaneously by placing the PCB panel into a seed bath, followed by immersion in an electroless copper bath. Such partitioned vias increase wiring density and limit stub formation in via structures. Such partitioned vias allow a plurality of electrical signals to traverse each electrically isolated portion without interference from each other.

  • Patent number: 8586133
    Abstract: A method is provided which includes forming a metal layer and converting at least a portion of the metal layer to a hydrated metal oxide layer. Another method is provided which includes selectively depositing a dielectric layer upon another dielectric layer and selectively depositing a metal layer adjacent to the dielectric layer. Consequently, a microelectronic topography is formed which includes a metal feature and an adjacent dielectric portion comprising lower and upper layers of hydrophilic and hydrophobic material, respectively. A topography including a metal feature having a single layer with at least four elements lining a lower surface and sidewalls of the metal feature is also provided herein. The fluid/s used to form such a single layer may be analyzed by test equipment configured to measure the concentration of all four elements. In some cases, the composition of the fluid/s may be adjusted based upon the analysis.

  • Patent number: 8551559
    Abstract: The invention relates to a method for producing a plastic molded part (9) comprising an integrated conductor path (3), which plastic molded part is used in particular as an intermediate product to be further processed into an electrically heatable mirror (1). The method steps are: a) producing a substrate (7) from a carrier body (2) made of an electrically insulating plastic material having a conductor path (3) made of an electrically conductive material on or in a surface (8) of the carrier body (2), b) flooding the surface (8) of the substrate (7) equipped with the conductor path (3) or the surface (11) of the substrate (7) opposite said surface with a liquid, electrically insulating coating material. The flooding evens out depressions due to uneven shrinkage in the thick and thin areas of the carrier body and a smooth surface can be produced, which can subsequently be covered with a reflective layer.
