Abstract

PURPOSE: To perform sealing with high reliability and high yield by inserting stoppers between the leads having been brazed to ceramics thereby preventing lateral direction deviations and positioning the package to the center of a fixing jig.
CONSTITUTION: A fixing jig 13 is provided with movable metal bars to insert stoppers 21 between leads 15. The stoppers protrude to the outer side by the tapers 23 of the forcing out part so as to be able to move from the inner to the outer side on the side face of the fixing jig. When a package 11 is removed, the stoppers are pulled inward by springs 24. According to this method, the deviations of the package with respect to the fixing jig is determined by the accuracy of the leads brazed to the package and the seal ring and since this value is made about 0.2 to 0.4mm, the accuracy improves considerably and the workability, yield and quality of seam weld sealing improve.
