Abstract:
An encapsulated optoelectrical component, comprising:an optocomponent assembly having a side or edge and an optical interface at the side or edge, the optocomponent assembly having areas for electrical connection and mechanical guide devices for positioning the optocomponent assembly in relation to another optical device having corresponding mechanical guide devices,an electrical circuit unit for cooperation with the optocomponent assembly and having areas for electrical connection,a plate-shaped carrier comprising an insulating material, the carrier comprising:a first area for attachment of the optocomponent assembly,a second area for attachment of the electrical circuit unit,electrical conductors for electrical connection tothe areas of the optocomponent assembly,the areas of the electrical circuit unit, andthe exterior,an encapsulating enclosure enclosing a main part of the optocomponent assembly or the electrical unit, the plate-shaped carrier, and the main part of the optocomponent assembly, the optocomponent assembly being located having the side or edge of the optocomponent assembly having the optical interface coinciding with a surface of the encapsulating enclosure,wherein the second area of the plate-shaped carrier for attachment of the optocomponent assembly is connected to the first area through a flexible portion of the carrier, the flexible portion substantially extending from the first area of the carrier for attachment of the electrical circuit unit and comprising electrical conductors arranged thereupon for conducting electrical drive voltages to and signals to and/or from the optocomponent assembly, the flexible portion of the carrier positioning, in an encapsulating operation for making the encapsulating enclosure, if the encapsulating enclosure encloses the main part of the optocomponent assembly, the electrical unit and the plate-shaped carrier, the optocomponent assembly at an accurately defined position in relation to a part of the component containing the electrical circuit unit, or if the encapsulating enclosure encloses only the optocomponent assembly, moving the optocomponent assembly in relation to the part of the component containing the electrical circuit unit, said part mountable to a circuit board, thereby positioning the optocomponent assembly and the optical interface in a correct position on the circuit board.
