Conductive adhesive is an adhesive with certain conductivity after curing or drying. It can connect a variety of conductive materials together to form an electrical path between the connected materials. In the electronics industry, conductive adhesive has become an indispensable new material. There are many kinds of conductive adhesives. From the perspective of application, conductive adhesives can be divided into general conductive adhesives and special conductive adhesives. General conductive adhesives only have certain requirements for the conductive performance and bonding strength of the conductive adhesives. In addition to certain requirements for the conductive performance and bonding strength, special conductive adhesives also have certain special requirements. Such as high temperature resistance, ultra-low temperature resistance, instant curing, anisotropy and transparency. According to the different types of conductive particles in the conductive adhesive, conductive adhesives can be divided into silver-based conductive adhesives, gold-based conductive adhesives, copper-based conductive adhesives, and carbon-based conductive adhesives. Silver-based conductive adhesives are the most widely used.

Conductive path is formed to make the conductive adhesive conductive. The stable contact between particles in the adhesive layer is caused by the curing or drying of the conductive adhesive. Before the conductive adhesive is cured or dried, the conductive particles are separated in the adhesive, and there is no continuous contact with each other, so they are in an insulating state. After the conductive adhesive is cured or dried, the volume of the adhesive shrinks due to the volatilization of the solvent and the curing of the adhesive, so that the conductive particles are in a stable continuous state with each other, thus exhibiting conductivity.
