<p>A producing method for metal-printed ceramic package is characterized by calcining ceramic and metal paste simultaneously after printing with paste of fine and coarse metal powder by control of oxygen partial pressure and dew point. In this method, the diameter of fine and coarse metal powder can be 0.5-1.5μm and 2- 5μm, respectively and the oxygen partial pressure is controlled from 10-9 to 10-50 atm. And its pretreatment temperature is controlled from 100 to 1400 deg.C, especially about 800 deg.C. The binder is made by addition of ethyl cellulose to a mixed solvent of butyl carbitol acetate and -terpinel and its viscosity is 10000±500 cps. It has advantages of controlling the constriction ratio, promoting the uniformity of surface resistivity and enhancing the cohesion strength of interface between ceramic and metal.</p> |
