Abstract
A method of fabricating a multi-layered PCB, in which the optical waveguide component is inserted into the PCB in such a way that a prepreg adhesive does not block an optical signal entrance of the optical waveguide. The method includes pre-routing a portion of an adhesive meeting the optical waveguide to remove the portion, processing an adhesive weeping prevention layer so as to prevent the adhesive from blocking the optical signal entrance of the optical waveguide, arranging the optical waveguide, the adhesive, and the adhesive weeping prevention layer on a copper clad laminate, and combining the optical waveguide, a prepreg, and the adhesive weeping prevention layer with each other into a single structure. The adhesive weeping prevention layer is selected from the group consisting of a prepreg, a single-sided copper clad laminate, a thermally curable resin, a heat spreader, and an unclad.
