METHOD OF MANUFACTURE OF PRINTED-CIRCUIT BOARDS Russian patent published in 1998 - IPC

Abstract RU 2109417 C1

FIELD: electrolytic methods of manufacture of printed-circuit boards. SUBSTANCE: the method consists in selective electrochemical etching of foiled dielectric at its motion relative to line sectional electrode-tool. The electrode-tool sections are controlled by photocells, which in the process of treatment move in the plane of the projected image of the printed-circuit board pattern. EFFECT: manufacture of printed-circuit boards of foiled dielectric. 2 dwg
