Patent ID: 7759155

Claim:
A method of manufacturing a packaged optical data transceiver comprising the steps of: providing an integrated control circuit for an optically active element; mounting and electrically connecting the integrated control circuit to a lead frame to form an integrated control circuit and lead frame assembly; inserting the integrated control circuit and lead frame assembly into a cavity of a moulding tool ensuring that at least a projection of the moulding tool is in contact with a portion of the surface of the integrated control circuit; introducing a plastic mould compound into the cavity so as to encapsulate, within a package, the integrated control circuit and lead frame assembly except for the portion in contact with the projection; removing the integrated control circuit and lead frame assembly from the cavity, whereby there is an opening defined in the package through which the portion of the surface of the integrated circuit in contact with the projection is exposed; and mounting and electrically connecting an optically active element or elements to the exposed portion of the integrated circuit.
