FIELD: radio electronics; manufacture of printed circuit boards.
SUBSTANCE: method of printed circuit boards manufacture consists in application of metal resistive coating on one side of copper or aluminium foil, and on other side pattern of electroconductive circuit is produced and protected with polymer. As a result, flexible printed circuit board is produced, with electric circuit with three sides protected by polyimide.
EFFECT: manufacture of flexible printed circuit boards without application of explosive and fire hazardous MOS, simplification and cost reduction of technological process, increase of printed circuit boards reliability.
