Abstract
Disclosed is an integrated optical detection packaging assembly for mounting and aligning a focus and tracking photo detector array and front facet detectors to an optical read/write head. A flat elongated leadframe having a plurality of conductive fingers extending substantially orthogonal to the longitudinal axis of the leadframe and having conductive wing areas extending along the longitudinal axis to opposite ends of the leadframe provides a support for the mounting of the packaged components to the read/write head of a CD reader/writer. The conductive wing areas have alignment indicia for facilitating the aligning of a focus and tracking photo detector array, carried by the support, to the optical reader/writer. A ceramic substrate is attached to the leadframe and a focus and tracking photo detector array is attached to the ceramic substrate and to the conductive fingers of leadframe. Front facet detectors are attached to the ceramic substrate and to the conductive fingers of said leadframe to complete one embodiment of the package.
