Abstract

The invention discloses a UV-curable conductive adhesive. The UV-curable conductive adhesive comprises, by mass, 5-20% of a modified acrylate oligopolymer, 10-35% of an acrylic acid monomer, 2-5% of a photoinitiator, 0.5-2% of an assistant and 5-80% a conductive heat conduction filler. The UV-curable conductive adhesive can substantially reduce the conductive adhesive curing time, and is convenient for realizing the fully automatic production of a whole technology in order to improve the production efficiency; and the curing time is short, so electric energy reduction benefiting, environmental protection, energy saving and production cost reduction are realized, and the requirements of the modern development and the improvement of the market competitiveness are satisfied.

Description

technical field [0001] The invention relates to a conductive adhesive, in particular to a UV curable conductive adhesive. Background technique [0002] With the rapid development of the electronics industry, the packaging technology of microelectronics is developing in the direction of high speed, high density, light weight, and miniaturization. Some traditional soldering materials such as Sn-Pb are far from meeting this refined technology. Therefore, the research and development of new materials with low energy consumption and environmental friendliness has become an inevitable development trend. [0003] The conductive adhesive has become a new type of connecting material to replace Sn-Pb solder due to its excellent characteristics. Conductive adhesive is a composite material composed of high molecular polymer and conductive particles. The polymer imparts connection properties, and the conductive particles impart electrical conductivity. Conductive adhesive has certain...
