AI Technical Summary

Problems solved by technology

[0003] The silver content of the conductive silver glue in the prior art is relatively high, which has caused the cost of the conductive silver glue to remain high. If other metals are used to replace it, in addition to the weakened conductivity, it will also cause the conductive silver glue to be cured. Poor shear strength, high temperature resistance and bond strength after curing

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.

Description

technical field [0001] The invention relates to conductive glue, in particular to a high-temperature-resistant conductive silver glue for producing LEDs. Background technique [0002] Conductive silver glue is a kind of conductive particles combined by the bonding effect of the matrix resin, and forms a conductive path to realize the conductive connection of the adhered materials. Conductive silver glue can be made into paste to achieve high line resolution. The conductive silver glue has a simple process and is easy to operate, which can improve production efficiency and avoid environmental pollution caused by heavy metal lead in tin-lead solder. At present, conductive silver glue has been widely used in the packaging and bonding of liquid crystal displays, LEDs, IC chips, printed circuit boards, radio frequency identification electronic components and components. [0003] The silver content of the conductive silver glue in the prior art is relatively high, which has cause...
