Abstract: Method for use in the manufacture of printed circuit boards (1) wherein the conductive circuit (3) placed on a dielectric substrate (2) includes a commoning portion (4) which electrically connects selected portions (5) of the printed circuit (3) which will subsequently be electroplated. The commoning portion (4) of the printed circuit (3) is peeled away from the substrate (2) after the selected portions (5) of the printed circuit are electroplated, leaving the electroplated portions (5) electrically separated, except as they might be otherwise electrically connected through other paths in the printed circuit board (1).

Abstract: A dicyandiamide crosslinked epoxy prepreg substantially free from dicyandiamide crystals is obtained by subjecting an epoxy composition containing dicyandiamide to elevated temperature to thereby form a substantially prereacted product, adding solvents if desired, desolvating, and then thermally advancing the prereacted product to the desired state of crosslinking to thereby form the prepreg.
