Zusammenfassung: | The invention discloses surface electrode silver paste for a chip type resistor. The surface electrode silver paste is prepared from the following raw materials based on weight percentages: 65-74% of silver powder with grain diameter of smaller than 5[mu]m, 0.5-5% of palladium powder, 0.5-5% of metal powder, 1-6% of glass powder, and 10-33% of organic carrier. The invention also discloses a preparation method for the surface electrode silver paste for the chip type resistor. The surface electrode silver paste for the chip type resistor can effectively solve the problems on the aspects of adhesive force, electroplating property, acid resistance, printing property and the like; the main technological goals of the products comprise resistance value precision, working voltage, temperature coefficient, voltage coefficient, stability and the like, and technologic indexes of the like products in Europe and America can be reached; and all the adopted materials can satisfy environment protection demands of foreign cou |
