Electronic circuit assembly with optical waveguide for interconnecting electronic components

摘要

A method of forming an electronic circuit assembly in which channels are formed in a surface of a circuit board e.g. by excimer laser drilling, and then filled with an optically transmissive resin material, to form an optical waveguide structure. A number of electronic devices are mounted on the circuit board, at least some of the devices including optical receiver and/or transmitter means for receiving/transmitting optical signals from/to the waveguide. An optical fibre is coupled to the waveguide.
