Abstract: PROBLEM TO BE SOLVED: To provide a method by which positioning of a laminate substrate or other substrates on a mold base is improved. SOLUTION: This alignment system of a photoelectric module has an overmolded chip carrier 26 and positions a substrate in a mold precisely to form an overmold frame 18 on the substrate. Co-operating stand-off pads 70, 71, 72 in a retainer assembly on the overmold frame stabilize an assembly of these components, and provide precise gaps to bond these two components permanently. The retainer assembly 36 has a co-operating feature for positioning an end electric lead of a flexible circuit in an electric pad array on the substrate. A nearby electric lead is protected by a permanent enclosing plate on a nearby edge portion of the flexible circuit and positioned by optic dies and an electric pad on their carriers.

Abstract: PROBLEM TO BE SOLVED: To precisely align a laminated substrate and other substrates on a mold base.
SOLUTION: An alignment system has overmolded chip carriers and precisely aligns the substrate within a mold. Cooperating standoff pads on an overmold frame and on a retainer assembly provide a precise gap to receive an adhesive. The retainer assembly carries optoelectronic components, including a flexible circuit, and a tip portion of the flexible circuit and a wall of a receiving cavity within the overmold frame have a cooperating feature, to precisely register a distal electrical lead of the flexible circuit with an array of an electrical pad on the board. A permanent shroud at an approximate end portion of the flexible circuit protects and helps to register approximate electrical leads with the electrical pad on optic dye and on these carriers.

Abstract: PROBLEM TO BE SOLVED: To provide an optoelectronic module having a miniaturized package size by improving the heat removal from optoelectronic chips and eliminating the crosstalk between the chips by means of a simplified structure, and then, using a simple and sure assembling method. SOLUTION: A heat sink for the transceiver optoelectronic module contains a double direct heat route, a structure surrounding many chips, and a central web which electrically separates a transmitter chip and a receiver chip from each other. A retainer used for an optical coupler has a port into which an epoxy is injected. On the over-molded base of the optoelectronic module, an epoxy flow managing member is formed. The assembling method of the optoelectronic module includes gap setting and a modified TAB bonding process.
