ABSTRACT:
A pair of conductive surfaces are provided on opposing surfaces of a vitreous or devitrified apertured insulator. A sheet of lead is prepared by electroplating gold on all surfaces thereof, and the insulators are pressed into a surface of the lead mask so that only a first one of the upper and lower surfaces of the member is exposed on said mask surface. A requisite conductive material is then provided on the exposed first one of the upper and lower surfaces of the insulating member and on said adjacent surface of the mask. The gold layer on the back surface of the mask is scraped away and the lead mask is then immersed in a solution which dissolves the lead. The freed insulators are then recovered and cleaned and the second one of the pair of conductive surfaces is applied to the second one of the upper and lower opposing surfaces of the insulator in a similar manner.
