<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an organic printed substrate capable of fabricating a cavity with high accuracy, and improving production yield and production efficiency. <P>SOLUTION: The method for manufacturing an organic printed substrate 50 comprises a laminating step for laminating prepregs 123a on a core base 21, and a cavity forming step for forming a recessed cavity 10 by removing a predetermined part of the prepreg 123a. The laminating step comprises a step for arranging a heat-resistant film 110 between the core base 21 and the prepreg 123a, and the cavity forming step comprises a step for forming a side wall part 11 of the cavity 10 on the prepreg 123a by cutting a part corresponding to the heat-resistant film 110 on the prepreg 123a by using laser, and a step for forming a bottom part 12 of the cavity 10 on a part where the heat-resistant film 110 on the core base 21 was present. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
