METHOD OF FORMING CHANNEL FOR TRANSMITTING OPTICAL SIGNAL BETWEEN ELECTRONIC MODULES ON ONE PRINTED-CIRCUIT BOARD

摘要

FIELD: radio engineering, communication.SUBSTANCE: invention relates to electronics and a method of forming a channel for transmitting an optical signal between electronic modules on one printed-circuit board. The method employs a head which contains a transparent polymer, placing a photoresist over a suitable area on the head and applying a die on said area. UV radiation exposure is carried out through the transparent mask of the die and the outer surface of the optical path of the hardened photoresist is coated with a light-reflecting metal layer by sputtering.EFFECT: simple method of forming a channel and improved performance of products.5 dwg
