Patents by Inventor Randolfo Galvez

Randolfo Galvez has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5108553
    Abstract: A thin, preferably flexible circuit having multiple conductive planes separated by a non-conductive layer is provided. Conductive vias electrically interconnect the conductive planes. The conductive vias comprise carbon coated blind vias which are made conductive by the electrolytic deposition of a metal on the carbon. The invention is particularly suited for G-TAB wherein a first metal plane is patterned into signal plane circuit traces and a second metal plane is patterned into ground plane traces.
    Type: Grant
    Filed: September 25, 1989
    Date of Patent: April 28, 1992
    Assignee: Olin Corporation
    Inventors: Craig A. Foster, Randolfo Galvez, Kurt R. Raab

  • Patent number: 4994153
    Abstract: Described herein is a process for treating the tooling holes or slots which have been coated with a carbon black dispersion in a nonconductive material which comprises removing said carbon black with an aqueous solution containing:(a) an alkanolamine;(b) an anionic surfactant which is the neutralized addition product of maleic and/or fumaric acid and a poly(oxylated) alcohol;(c) a nonionic surfactant which is an aliphatic mono and/or diphosphate ester; and(d) an alkali or alkaline earth metal hydroxide.
