Abstract:
1. A method of attaching an optical waveguide component to a printed circuit board having a plurality of conductive layers and dielectric layers, which comprises: counter-bowling the printed circuit board in a level-differentiating mode along the predetermined pattern to form a groove for receiving the optical waveguide component, with one of the dielectric layers being exposed in the groove and with the exposed dielectric layer having reduced thickness compared with the original thickness thereof to a degree that no residue of conductive layer substantially remains on the exposed dielectric layer; providing the optical waveguide component on which a surface roughness is exhibited; positioning the optical waveguide component in the groove along with an adhesive tape layer, the adhesive tape layer being interposed between the optical waveguide component and the groove, followed by pre-bonding through a hot press to form a pre-bonded structure; and main-bonding the pre-bonded structure by pressing under the condition of a predetermined temperature and pressure.
