LIGHT-REFLECTIVE ANISOTROPIC ELECTRICALLY CONDUCTIVE PASTE, AND LIGHT-EMITTING DEVICE

摘要

This light-reflective anistropic electrically conductive paste can be used when manufacturing a light-emitting device by flip-chip mounting light-emitting elements such as light-emitting diode (LED) elements on a circuit board, can suppress a reduction in the strength of the adhesion of the light-emitting elements to the wiring board in a high-temperature environment, and can suppress a reduction in conduction reliability after TCT, when light-reflective insulting particles in order to improve light-emitting efficiency without equipping the LEDs with a light-reflective layer that would increase manufacturing cost. The light-reflective anisotropic electrically conductive paste is formed by dispersing conductive particles and light-reflective insulating particles in a thermosetting resin composition, and the thermosetting resin composition contains an epoxy compound and a thermal catalyst-type hardening agent.
