Method of manufacturing optical communication module, and optimum mold and lead frame for use in the manufacturing method

摘要

A method of manufacturing an optical communication module, and a mold and a lead frame that are suitable for the method are provided. The method comprises the steps of: placing in a mold the lead frame on which a ferrule and an optical communication facility section are mounted; pressing the ferrule by a moving part that can be stopped at a given position relative to the mold (lower mold tool) such that the distal end of the ferrule is positioned at a proper location within the mold; and filling a resin into the mold, wherein a displacement and a reactive force generated in the lead frame when it is pressed are absorbed by springs provided in the lead frame when it is pressed are absorbed by springs provided in the lead frame such that a catching portion for coupling to a connector is formed with high accuracy at a proper position relative the distal end of the ferrule.
