Abstract
Abstract In a method for manufacturing a module for a fiber optic link, a plate-shaped transparent circuit unit (24) is molded in advance. The circuit module (24) is transfer molded together with an optoelectronic element (30) connected to leads (28-2). The circuit module (24) is clamped betweeen a pair of rod- shaped first dies (42, 44) which have a common central axis and one of which defines an optical path of the module, in such a manner that the optoelectronic element (30) is located on a central axis of the circuit module (24). Under this condition, the circuit module (24) is housed in a cavity defined by a pair of second dies (46, 48). A light-shielding molding material is injected into the cavity for injection molding to mold a case (20). After the case (20) is cured, the first and second dies (42, 44, 46, 48) are removed, and the hole of the case (20) formed by one of the first die (44) is closed with a cap to complete a receptacle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
186 words
A method for manufacturing a module for a fiber optic link, characterized by comprising the steps of: transfer molding a transparent first member (24) which has a predetermined shape, in which is embedded an optoelectronic element (30), and which is mounted on one of leads (26-1, 26-2, 26-3, 26-4, 26-5) extending outwardly therefrom; clamping said first member (24) between a pair of first dies (42, 44) of rod shape which have a common central axis and one of which defines an optical path (19) in the module, so that said optoelectronic element (30) of said first member (24) is positioned on said central axis; injection molding a second member (20) by positioning said first member (24) clamped by said first dies (42, 44) in a cavity of second dies (46, 48) conforming to an outer shape of said second member (20), and injecting a light-shielding molding material in said cavity (50); and removing said first and second dies (42, 44, 46, 48) and covering, with a light shielding cap (52), a hole of said second member (20) formed by the other of said first dies (48).
Claim 2
Independent Claim
186 words
A method for manufacturing a module for a fiber optic link, characterized by comprising the steps of: transfer molding a transparent first member (24) which has a predetermined shape, in which is embedded an optoelectronic element (30), and which is mounted on one of leads (26-1, 26-2, 26-3, 26-4, 26-5) extending outwardly therefrom; clamping said first member (24) between a pair of first dies (42, 44) of rod shape which have a common central axis and one of which defines an optical path (19) in the module, so that said optoelectronic element (30) of said first member (24) is positioned on said central axis; injection molding a second member (20) by positioning said first member (24) clamped by said first dies (42, 44) in a cavity of second dies (46, 48) conforming to an outer shape of said second member (20), and injecting a light-shielding molding material in said cavity (50); and removing said first and second dies (42, 44, 46, 48) and covering, with a light shielding cap (52), a hole of said second member (20) formed by the other of said first dies (48).
