PCT No. PCT/GB84/00441 Sec. 371 Date Oct. 21, 1985 Sec. 102(e) Date Oct. 21, 1985 PCT Filed Dec. 19, 1984 PCT Pub. No. WO85/02969 PCT Pub. Date Jul. 4, 1985.Copper substantially free of micro-pores is electrodeposited on a polished surface of a stainless steel, titanium, or chromium-plated steel press plate. The copper layer is then provided with a matte surface of copper of dendritic structure which is subsequently bonded to a dielectric material under the application of heat and pressure in a laminating press. The resulting copper-clad dielectric board separates from the press plate, which can then be re-used.
