    • PURPOSE: A method for manufacturing a wiring board is provided to form a wiring pattern directly on the end surface of the via formed by filling the through hole formed at a substrate with a metal through a plating process. CONSTITUTION: A method for manufacturing a wiring board, comprises a step of forming a through hole(12) at a substrate(10) so as to define openings at the first and second surfaces of a wiring board; a step of plating the substrate with a metal such that a metal layer of a predetermined thickness is formed on the first and second surfaces of the wiring board and the through hole is substantially filled with the metal so as to form a via; and a step of irradiating a laser beam of a plurality of spots around the non-filled portion of the plated metal, including a dimple(20) or a seam, such that a certain part of the plated metal melts and the non-filled portion is filled with the molten metal.
    • 目的:提供一种制造布线板的方法,以通过电镀工艺将金属填充在基板上形成的通孔形成在通孔的端面上直接形成布线图案。 构成:一种制造布线板的方法,包括在基板(10)上形成通孔(12)以在布线板的第一和第二表面处限定开口的步骤; 用金属电镀基板的步骤,使得在布线板和通孔的第一和第二表面上形成预定厚度的金属层基本上被金属填充以形成通孔; 以及将包含凹坑(20)或接缝的电镀金属的未填充部分周围的多个点的激光束照射的步骤,使得电镀金属的某一部分熔融,并且未填充部分 填充有熔融金属。
