Description

technical field [0001] The invention relates to the technical field of conductive glue, in particular to a graphene conductive glue. Background technique [0002] Conductive adhesive is an adhesive with a certain conductivity after curing or drying. It usually uses matrix resin and conductive fillers, namely conductive particles, as the main components. The conductive particles are combined through the bonding effect of the matrix resin to form a conductive adhesive. Pathway to realize the conductive connection of the adhered material. Since the matrix resin of the conductive adhesive is an adhesive, a suitable curing temperature can be selected for bonding. At the same time, due to the miniaturization and miniaturization of electronic components and the rapid development of high density and high integration of printed circuit boards, The conductive adhesive can be made into a paste to achieve high line resolution. Moreover, the conductive adhesive has a simple process, is...
