摘要:
PROBLEM TO BE SOLVED: To provide a printed circuit board manufacturing method for selectively removing molten scattered Cu and overhang with almost no reduction of a wiring thickness, and to provide electrolytic etching treatment liquid suitable thereto. SOLUTION: In the printed circuit board manufacturing method, a hole is laser-machined in a multilayer substrate on which copper layers 3 and insulating layers 1 are alternately laminated, ranging from the copper layer 3 on the surface thereof to the copper layer 2 as the inner layer. In this case, the hole machining steps include a step of forming a laser absorption layer 4 on the surface of the copper layer 3 arranged on the surface, a laser irradiation step, an electrolytic etching treatment step, and a removing treatment step for the laser absorption layer 4, in sequence.
