  • Method for manufacture of multilayer printed circuit boards
    Patent number: 4921777
    Abstract: This method relates to a process for manufacturing printed circuit boards in which a metal coating is sputtered onto certain regions of a substrate. Adhesion of the sputtered material is excellent. Surface preparation of the substrate and etching thereof prior to sputtering are virtually eliminated. Films deposited by sputtering exhibit uniform coverage and thickness.

  • Metal plating of plastic materials
    Patent number: 4803097
    Abstract: This invention relates to a process for conditioning the surfaces of natural and synthetic plastic materials for electroless plating of a metal coating thereon exposing such materials to an atmosphere comprising ozone, contacting said exposed materials with a conditioning solvent, such as an aqueous solution of sodium, potassium or lithium hydroxide, contacting said materials with one or more oxidizing acids such as nitric acid and electroless plating of a metal coating on the said material.
