Abstract: During the development and use of varistors, around the feasibility analysis of the process manufacturing technology direction of small volume low capacitance chip varistors, the key technologies such as material formulation, sintering technology and product surface insulation treatment are studied, and the domestic production technology level of varistors and the development status of foreign counterparts' varistors are reported. The structural design, parameter design, process route research direction and product application direction (such as product response speed and high integration) of small volume low capacitance chip varistor products are briefly summarized. The technical risk and schedule risk problems existing at all levels are analyzed, and solutions and ideas are proposed to reduce the risk coefficient. The decomposition of the dielectric material formula of the manufacturing process of the chip varistor and the key technologies of surface insulation treatment of the product are discussed.
