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.

摘要： A fabricating method of a printed circuit board (PCB) with a cavity and a structure of the PCB fabricated by the method are provided. The method includes a first step of forming a base circuit board provided with an internal circuit layer having cavity circuit patterns on a surface of a substrate, a second step of forming a laser stopper layer on upper portions of the cavity circuit patterns, a third step of forming at least one external circuit layer on the base circuit board, and a fourth step of forming a cavity region by removing the external circuit layer on an upper portion of the laser stopper layer. Accordingly, in a fabricating method of a multi-layered PCB with a cavity, a laser stopper layer is formed on upper surfaces of cavity circuit patterns, so that it is possible to rapidly and precisely form the cavity, to precisely control the depth of the cavity and to have no influence on a circuit previously formed in the interior of the cavity.
