MANUFACTURING METHOD OF PCB

摘要

PURPOSE: A method for manufacturing a printed circuit board is provided to accomplish process simplification, by eliminating a surface roughness formation process. CONSTITUTION: A circuit pattern(120) is formed on an insulation substrate(110). An ink mask layer(130) is formed on the circuit pattern. A metal pattern zone is formed by processing the ink mask layer. A metal pattern(140) is formed on the metal pattern zone. An electronic element chip(150) is mounted in the metal pattern. The ink mask layer includes acrylic resin and solvent.
