    摘要: Alignment systems for optoelectronic modules with overmolded chip carriers include drilled or milled substrate corners for engaging dowel pins to precisely align the substrate in a mold for molding an overmold frame on the substrate. The overmold frame includes slot and trilobe holes for receiving retainer posts to precisely align a retainer assembly on the overmold frame. Cooperating standoff pads on the overmold frame and on the retainer assembly stabilize the assembly of these components and provide a precise gap for receiving an adhesive to permanently attach these two components. The retainer assembly carries optoelectronic components that include a flexible circuit, and a distal end portion of this flexible circuit and walls of a receiving cavity in the overmold frame have cooperating features for precisely aligning distal electrical leads of the flexible circuit with an array of electrical pads on the substrate. A permanent shroud on a proximate end portion of the flexible circuit protects and helps align proximate electrical leads with electrical pads on optic dies and their carriers.

    摘要: A plug which has a plugging portion and a stem extending therefrom is formed of an elastomeric material in order to deform to create a wiping engagement and a seal with the walls of a receiving cavity. The stem and plugging portion include both cavities for receiving alignment pins in the device being plugged and a manually engageable portion on a distal end of the stem for removing the plug from the sealed cavity, such as within an optical subassembly module. The side edges of the plugging member conform to the cavity cross-section to enhance the sealing yet do not unduly deform the member. The sealing member is formed with one or more standoffs to engage an end face of the cavity, assuring no contact between the optical elements and the plug. The edges of the plug deform upon insertion to create the seal and form a wiping engagement with the cavity interior.
