<P>PROBLEM TO BE SOLVED: To resolve the problem that using a single resin layer in a resin portion of a resin composite lead frame for optical devices makes it impossible to achieve both maintainability of a reflection coefficient against aging and stiffness and strength required for a package. <P>SOLUTION: When a silicone resin 3 is used for a resin layer on the outermost surface and an epoxy resin 2 is used for one of resins of lower layers, a resin composite lead frame for LED can be obtained which has high maintainability of a high reflection coefficient against aging, high stiffness and high strength, because of a high light transmissive property and a high photo-degradation resistance of the silicone resin and a high-stiffness and high-strength property of the epoxy resin. <P>COPYRIGHT: (C)2010,JPO&INPIT |
