RELIEF IMAGINE

摘要

A method of relief imaging liquids, particularly in manufacturing circuit boards, by providing a film of liquid photopolymer, solidifying the liquid by chemical hardening using actinic light, then pattern exposing the solidified film to actinic light to differentially chemically condition the film and then removing the portions of the film not exposed to the patterened exposure of actinic light. Also the product produced by the method.
