Electron Microscope Investigation of Mixed Stannous Chloride/ Palladium Chloride Catalysts for Plating Dielectric Substrates

Abstract

The present investigation represents a detailed study involving transmission electron microscopy and electron diffraction of surfaces treated by the catalyzing system in conjunction with various accelerating solutions and in some cases a subsequent electroless copper bath. Results give additional information demonstrating the proper procedure(s) necessary in the preparation of the catalytic system. In addition it was found the best plating results are obtained whenever is present on the treated surface prior to the metallization step.
