WHITE CURABLE COMPOSITION FOR OPTICAL SEMICONDUCTOR DEVICE, WHITE TABLET FOR OPTICAL SEMICONDUCTOR DEVICE, MOLDING FOR OPTICAL SEMICONDUCTOR DEVICE, AND OPTICAL SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a white curable composition for optical semiconductor devices, from which a tablet hardly causing chips and excellent in homogeneity can be obtained and a molding with less defects in appearance can be obtained.SOLUTION: The white curable composition for optical semiconductor devices includes an epoxy compound, an acid anhydride curing agent, a white pigment, a filler other than the white pigment, and a cure accelerator. The white curable composition for optical semiconductor devices is subjected to a compression pressure of 3 t to be formed into a columnar tablet with a diameter of 13 mm and a height of 30 mm. The columnar tablet has a compression modulus of 100 MPa or more and 2000 MPa or less, and a compression strength of 300 N or more.
