METHOD OF AND DEVICE FOR COATING PRINTED-CIRCUIT BOARD WITH PHOTOPOLYMERIC LAYER Russian patent published in 1994 - IPC

FIELD: radio electronics. SUBSTANCE: photopolymeric material is applied to carrier strip, partially polymerized, carrier strip is bent together with partially polymerized material into loop with loop bend facing PCB direction of movement; one of bend ends appears in displacement plane of PCB surfaces and its other end is locked in respect to PCB displacement plane; PCB is wetted with liquid polymeric material and pressed to partially polymerized photopolymeric material applied to carrier strip with layer of partially polymerized photopolymeric material in respect to displacement plane of PCB surface and its displacement mechanism. EFFECT: facilitated procedure. 4 cl, 4 dwg
