Abstract:
A method of connecting an optoelectronic waveguide device to a lead frame assembly comprising mounting the optoelectronic waveguide device on a planar substrate having electrical connecting circuitry for connection to the optoelectronic waveguide device, connecting said device to said connecting circuitry, providing a plurality of solder bumps on a major face of the substrate adjacent an edge of the face, the solder bumps being in electrical connection with said connecting circuitry, mounting the substrate on a lead frame support which engages said major face adjacent its periphery, said lead frame support having lead frame conductors exposed on said support so as to contact said solder bumps, and applying heat to melt the solder and thereby form secure electrical connections between the lead frame conductors and the solder bumps.
