Abstract:
A method of making an optical module in which an optical module principal portion is molded by means of a mold die, said mold die having a ferrule receiving portion for accommodating a ferrule and a positioning portion which are located at a lead frame mounting surface; said method comprising the steps of:preparing a lead frame having an alignment hole for enabling positioning with respect to said positioning portion of said mold die;preparing said optical module principal portion; said optical module principal portion including an optical device, an optical fiber optically coupled to said optical device, and a ferrule covering a side face of said optical fiber;securing said lead frame and said optical module principal portion to each other by means of a positioning jig so that said ferrule included in said optical module principal portion meets said ferrule receiving portion of said mold die;placing said lead frame with said optical module principal portion secured thereto at said mold die; andresin-molding said lead frame and said optical module principal portion by means of said mold die;wherein said securing step comprises the steps of:preparing said jib, said jig having a ferrule attachment portion and a lead frame positioning portion so as to correspond to said ferrule receiving portion and positioning portion of said mold die, respectively, said ferrule attachment portion and lead frame positioning portion allowing said optical module principal portion to be positioned with respect to said lead frame;placing said lead frame on said jig such that said alignment hole of said lead frame aligns with said lead frame positioning portion of said jig;mounting said optical module principal portion on said lead frame placed at said jig such that said ferrule included in said optical module principal portion aligns with said ferrule attachment portion; andsecuring said optical module principal portion mounted on said lead frame.
