Optical module and a method of fabricating the same

摘要

In the method of making an optical module in accordance with the present invention, an optical module principal portion is molded by means of a molding die. The molding die has a ferrule accommodating portion f or accommodating a ferrule and a positioning portion which are located on its lead frame-mounting surface. The method of making an optical module comprises the steps of: preparing a lead frame having an alignment portion enabling the positioning with respect to the mold die; preparing the optical module principal portion; aligning the optical module principal portion with the lead frame and securing them to each other by means of a positioning jig so that the ferrule secured to the optical module principal portion meets the ferrule accommodating portion of the molding die; placing the lead frame with the optical module principal portion secured thereto on the molding die; and resin-molding the lead frame and the optical module principal portion by means of the molding die.
