FIELD: process engineering.
SUBSTANCE: invention relates to sputtering of thin films in vacuum with the help of reeling machine, particularly, to production of RFID-antennas for radio-frequency identification marks. Proposed method comprises the stage of selective surface copper spraying with further copper layer build-up by electrolytic process. Selective spraying of polymer material is conducted in vacuum with preliminary application of mask coat on polymer surface, perfluorine polyether being used as the polymer, and with thermal copper spraying on polymer substrate.
EFFECT: increased current conductivity and decreased impedance of conducting layer on substrate.
