METHOD OF CONTINUOUS SELECTIVE DEPOSITION OF COVER ON BELT-TYPE BASE IN VACUUM Russian patent published in 1994 - IPC

FIELD: electronic engineering. SUBSTANCE: method provides for: masking, exercised by preliminary forming a roll by joint reel up of a belt-type base and located on its outer surface masking means on a drum ( maximum diameter of a ready roll must not exceed 1.2 of the drum diameter ); metal vapor deposition under pressure of not higher , than 1·10^-5 mm Hg on the formed roll during its unreeling and metal vapor condensation speed of 0.01 - 0.1 microns/s; following separation of the belt-type base and masking means. EFFECT: method allows to simplify process and increase production of good quality belt, using vacuum metal vapor deposition. 3 cl, 2 dwg 1 tbl
