Abstract

The invention discloses a low-melting-point glass sizing agent, which is prepared from, by weight percent, 50-80% of glass powder, 1-10% of inorganic pigment, and 19-40% of organic carrier; the glass powder is prepared from, by weight percent, 10-30% of B2O3, 10-25% of SiO2, 50-70% of Bi2O3, and 1-10% of Nb2O5; the inorganic pigment is inorganic composite oxide and consists of at least two transition metal oxides; the organic carrier is prepared from, by weight percent, 10-30% of high-molecular polymer, 40-85% of organic solvent, 5-30% of organic additive. The low-melting-point glass sizing agent is used for a thick film type resistor and excellent in both printing property and insulation property. The invention can effectively solve the problems of glass packing sizing agent in resisting acid, electroplating, heat impact and others; the materials can meet the EU RoHS environmental-friendly requirements.

Description

technical field [0001] The invention relates to the technical field of electronic materials, in particular to a low melting point glass paste and a preparation method thereof. Background technique [0002] Low melting point glass paste, also called glass encapsulation paste, is a kind of thick film dielectric paste, which is specially used to protect chip resistors, thick film resistor networks and thick film hybrid integrated circuits, encapsulating a layer of glass glaze on the surface of components It is the most effective method to improve the stability of thick film components under hot and humid conditions and protect the surface from mechanical damage. The low melting point glass protective paste is composed of low melting point glass, inorganic pigment and organic vehicle. The requirements for the low-melting point glass protective paste are: low sintering temperature, little impact on the encapsulating resistance film, acid resistance, electroplating resistance, th...
