Abstract

1,194,853. Printed circuits. B.T.R. INDUSTRIES Ltd. 19 Jan., 1968 [16 Feb., 1967], No. 7437/67. Heading H1R. A printed circuit is formed on a copper clad panel 8 (Fig. 1) having copper foil 14 bonded to an insulating substrate 10, drilled holes 12, copper-plating 16 on the hole walls and foil, as follows:-Hole 12 is filled with viscous cellulose black printing ink 18 (Fig. 2). The sequined conductor pattern is then printed with etch resistant ink 20 (Fig. 3) and panel 8 is etched in known manner leaving the conductor pattern as shown in Fig. 4. The inks are then removed leaving the printed circuit board Fig. 5. The circuits are then given a final surface of gold by a known immersion process.
