  • Conditioning of a substrate for electroless plating thereon
    Patent number: 5318803
    Abstract: A dielectric substrate is conditioned for subsequent electroless plating thereon by contacting with a catalytic metal salt and then with a reducing agent and with an electroless metal plating bath followed by contacting with a second catalytic metal salt. In addition, a dielectric substrate is conditioned for electroless plating thereon by obtaining a substrate of a dielectric material that contains metal particles therein and contacting with a catalytic metal salt.

  • Electrophoretic insulation of metal circuit board core
    Patent number: 4714646
    Abstract: A printed circuit with an internal metal sheet for heat dissipation has a roughened aluminum sheet with via holes coated with acrylic or epoxy resin containing thixotropic fumed silicon dioxide or silicate clay. The resin and thixotropic agent are electrophoretically coated. The thixotropic agent may act both to even the coating around edges and as a material upon which metal plating of the printed circuit is bonded.

  • Resistive substrate for thermal printing ribbons comprising a mixture of thermosetting polyimide, thermoplastic polyimide, and conductive particulate material
    Patent number: 4421429
    Abstract: Disclosed is a thermal transfer medium which comprises a mixture of a thermosetting polyimide, a thermoplastic polyimide, and graphite. It has a steel support layer and an intermediate layer of silicon dioxide. An outer layer on the steel is the thermal ink. The mixture is applied as a dispersion with a precursor of the thermosetting polyimide. The ribbon may be recoated at the typing station by applying a hot melt of the ink.

  • Silicon dioxide intermediate layer in thermal transfer medium
    Patent number: 4419024
    Abstract: Disclosed is a thermal transfer medium which comprises a mixture of a thermosetting polyimide, a thermoplastic polyimide, and graphite. It has a steel support layer and an intermediate layer of silicon dioxide. An outer layer on the steel is the thermal ink. The mixture is applied as a dispersion with a precursor of the thermosetting polyimide. The ribbon may be recoated at the typing station by applying a hot-melt of the ink.
