Conductive paste |
摘要 |
A conductive paste having excellent printing properties, which can be used for manufacturing heat-resistant conductors and resistive elements, is described. Such a conductive paste can be obtained by preparing as a binder a polyimide precursor whose weight average degree of polymerization (n) ranges from 5 to 20, and mixing it with a solvent and a conductive powder. The polyimide precursor preferably is included in the range from 50 to 80 weight parts to 100 weight parts of the solvent. A polar solvent, or a mixed solvent including a polar solvent and a nonpolar solvent can be used. A preferable mixed solvent is a mixture of N-methyl-2-pyrrolidone and diethylene glycol dimethyl ether, in which the mixing volume ratio is preferably ranging from 2:8 to 9:1, more preferably, 2:8 to 3:7.
