| Abstract: | This paper conducts research on kovar alloy(4j33)and ceramic(Al2O3-95%)under the high temperature expansion feature,and analyses and calculate the difference of using flat seal structure and seal structure expansion deformation,determines two kinds of packaging structure after brazing joint tensile strength of the differences.The results showes that with the vertical sealing structure,the tensile strength of kovar alloy ceramic joint is nearly 4 times higher than that of flat seal. |
