Abstract

The invention relates to a high-temperature-resistant conductive silver adhesive used for production of an LED. The conductive silver adhesive comprises the following materials in parts by weight: 50parts of polyester resin; 50 parts of epoxy resin; 40 parts of silver powder; 10 parts of nickel powder; 10-12 parts of polymethyl methacrylate; 10-12 parts of an ethylene-ethyl acrylate copolymer; and 6-7 parts of a surfactant. According to the conductive silver adhesive provided by the invention, the formula of a conductive silver adhesive with a low silver content is improved and optimized, sothat the conductive silver adhesive has excellent high-temperature-resistant performance and higher and more stable bond strength with a circuit board and components after being cured, and helps to improve the structural stability of the LED after being used for a long time.
