Abstract:
     The invention relates to a method for producing the new paster macromolecule base ESD protective device, which comprises: preparing preset pattern on the copper layer of PCB board; proportioning the raw materials for preparing the core material; preparing slurry and printing the core material; solidifying the core material; printing the packing layer; solidifying the packing layer and the upper electrode; incising; detecting the appearance; and classifying. Wherein, the prepared core material is compound material comprising macromolecule adhesive, conductive particles, insulated particles, and semi-conductive particles, while said macromolecule adhesive is one or the mixture of organic silicon resin, epoxide resin and rubber; said conductive particle is one or mixture of nickel powder, nickel carbonoxide and aluminum powder; said semi-conductive particle is one or mixture of zinc oxide, barium titanate and silicon carbide; and said insulated particle is one or mixture of silicon dioxide, alumina and magnesia.
