With the development of electronic technology,导电胶As an electronic interconnection material, it is increasingly applied in surface packaging and chip interconnection. As an alternative to the traditional Sn/Pb solder, conductive adhesives have the advantages of low curing temperature, simple process and environmental friendliness.

　　Conductive adhesive is a type of adhesive formed by dispersing conductive particles in a resin matrix. After curing and drying, it has conductive properties similar to those of metals. It has certain bonding properties. By bonding different conductive materials together, it enables the formation of conductive pathways between these materials for conducting electricity. Before curing, the conductive adhesive is a paste-like liquid that can flow. It can be cured through heating or ultraviolet light exposure, and the cured product meets certain properties, such as stable conductivity and a certain shear strength. 
According to the electrical conduction mechanism of conductive adhesives, the general selection principle is that particles should be able to form more contact areas. There are various shapes of silver powder, such as sheet-like, spherical, dendritic, and irregular shapes, and different types of silver powder should be selected according to different applications. In conductive adhesives, sheet-like silver powder is generally used in larger quantities, with diameters typically ranging from 1 to 10 micrometers. Syaya paste can customize different specifications of sheet-like conductive silver powder for customers. For example, the sheet silver used for LED dispensing and for touch screen circuits has significant differences in parameters and performance.
