摘要:
Disclosed are a printed circuit board and a method for manufacturing the same. The method for manufacturing the printed circuit board includes forming a base circuit board including a cavity circuit pattern in a cavity region on upper and lower portions of a substrate and internal circuit layers outside the cavity region, forming a cavity separation layer on the cavity circuit pattern, forming at least one pair of an insulating layer and a circuit layer on the base circuit board, cutting the insulating layer and the cavity separation layer provided on an etch stop pattern by controlling a focal length of a laser beam such that the laser beam reaches a surface of the base circuit board, and removing the insulating layer by separating the cavity separation layer to form the cavity. The cavity separation layer is formed on the cavity circuit pattern, and the resultant structure is cut to the cavity separation layer by using a laser so that the insulating layer is separated. Accordingly, the insulating layer in the cavity is easily removed.
