Abstract
1340260 Sealing glass to metal SAN FERNANDO ELECTRIC MFG CO 19 April 1971 27012/71 Heading C1M [Also in Division H1] An electrical component has leads attached to it and is encapsulated by placing the component, e.g. chip capacitor 44 with metallized ends 46, within glass sleeve 36, pressing the enlarged head portions 22<SP>1</SP> of leads 201 against the metallized ends within the enclosure formed by recesses in graphite plates 32, 48, passing reducing gas, e.g. a mixture of nitrogen and hydrogen through the enclosure optionally after evacuation, then evacuating the enclosure, the assembly being heated to about 300� C. beginning just before stopping the reducing gas purge and ending before the end of the evacuation, then inert gas is passed through the enclosure while heating the assembly to join the heads to the metallized ends and seal the glass sleeve to the heads and finally cooling the assembly in the inert gas flow. The final heating in inert gas may be at 750- 760� C. The assembly may be removed without risk of oxidation when it has cooled to below 300� C. The enlarged heads of the leads may have a glass bead previously fused thereto by a similar sequence of steps (Figs. 1 to 5, not shown). The heads 22<SP>1</SP> may be of a nickel-iron alloy and leads 20<SP>1</SP> of copper, or both may be of the same alloy.
