Description

technical field [0001] The invention relates to a conductive adhesive. Background technique [0002] Conductive adhesive is an adhesive with certain conductivity after curing or drying. The usual preparation method is to use matrix resin and curing agent as film-forming substances, conductive fillers as conductive additives, and combine conductive particles through the bonding effect of matrix resin. Form a conductive network channel to realize the conductive connection of the bonded materials. The main components of conductive adhesives are matrix resin, curing agent, conductive additives and auxiliary agents. Conductive adhesives are used in a wide variety of applications including metal chassis connections, bonding wires to headers, bonding components to planar holes through printed wiring, bonding waveguide tuning, and hole repair. However, the existing conductive adhesives are difficult to disperse evenly in the adhesive system, which greatly reduces the adhesiveness ...
