Abstract
A hybrid electro-optical circuit board including a plate, a light guiding hole and a light-guide device. The light guiding hole is formed in the plate to be connected to an upper surface and a lower surface of the plate. The light-guide device is formed on the lower surface and covers and contacts the light guiding hole. An optical signal is transmitted between the light-guide device and the upper surface of the plate via the light guiding hole. A metal layer is further formed on an inner wall of the light guiding hole, to reduce the roughness of the inner wall and reflects the optical signal by the reflection characteristics of metal. Further, the light guiding hole is filled with a transparent substance to transmit the optical signal and to stop foreign material from entering the light guiding hole.
