Abstract:
1. A method for manufacturing optical electrical components employing a die, the die including a top piece, a bottom piece having a plurality of cavities and being arranged opposite to and below said top piece, and an intermediate piece arranged between said top and bottom pieces, and a mold release film covering said plurality of cavities to seal and mold an optical device in each of said plurality of cavities with resin, comprising: attaching to said top piece a substrate having the optical devices mounted thereon; bringing said mold release film which is sandwiched between said bottom and intermediate pieces into contact with each surface of said plurality of cavities along a geometry of said plurality of cavities; setting said melted resin or said resin in liquid form to result in a transparent set resin; separating said top, bottom, and intermediate pieces; removing from said top piece said substrate having said optical devices sealed in said transparent set resin; and forming optical electronic components by cutting said substrate having said optical devices sealed in said transparent set resin, wherein in said closing step, said optical device is inserted into said melted resin or said resin in liquid form within each of said plurality of cavities, and thereby, said melted resin or said resin in liquid form moves between said plurality of cavities through a communication path provided at a whole periphery of each of said plurality of cavities so that a space in each of said plurality of cavities is filled with said melted resin or said resin in liquid form.
