PCB AND FABRICATING METHOD OF THE SAME

摘要

PURPOSE: A printed circuit board and a manufacturing method thereof are provided to improve the reliability of a pattern by burying a circuit pattern in an insulation member. CONSTITUTION: A first circuit pattern is formed by processing a base substrate with an insulation layer and a metal conductive layer which are laminated on both sides of a separating member. The insulation layer with a first circuit pattern is separated based on the separating member. The first circuit pattern is buried in the second insulation layer. Metal materials are filled by forming a circuit pattern area by processing a second insulation layer.
