ETCHING METHOD AND MANUFACTURING METHOD FOR PCB USING THE SAME

摘要

PURPOSE: An etching method and a circuit board manufacturing method using the same are provided to be capable of forming a fine circuit pattern. CONSTITUTION: An etching target is provided(S110). An etching resist is laminated where a fuse pattern and a slit cutting the fuse pattern are formed at the etching target(S120). A fuse in accordance with the fuse pattern is formed, and the etching target is etched until the fuse exposed by the slit is cut(S130).
