  • Printed circuit board with aligned connections and method of making same
    Patent number: 5450290
    Abstract: The present invention provides an improved circuit board for mounting integrated circuit chips and a technique for manufacturing the circuit board. The board permits direct chip attachment to the circuit board by providing the necessary geometry for the footprint pattern of the chip connections without the necessity of multi-level packaging using chip carriers. The circuit board includes a substrate with plated through holes, and a film of photoresist dielectric material disposed on the substrate. The dielectric material is photo patterned to form vias which are then filled with conductive material. Electrical connection pads are formed on the exposed surface of the film of dielectric material in the pattern of the chip footprint to be mounted thereon.

  • Electrolytic process for reducing the organic content of an aqueous composition and apparatus therefore
    Patent number: 5230782
    Abstract: The total organic content (TOC) of an aqueous composition is reduced to 200 ppm or less by subjecting the composition to electrolysis whereby the pH of the composition at the start of the electrolysis is about 1.8 to about 7 to thereby electrolytically decompose organic materials contained in the aqueous composition.
