    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.
