technical field [0001] The invention relates to the field of electric tools, in particular to a conductive adhesive tape. Background technique [0002] Usually, the conductive tape is mainly composed of matrix resin and conductive filler, namely conductive particles. The conductive particles are combined through the bonding effect of the matrix resin to form a conductive path and realize the conductive connection of the adhered materials. 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 easy to operate, and can improve production efficiency. Therefore, the conductive adhesive is an id...
