Abstract
An electrical component 11 having a body 12 and a pair of terminals 16, 17 extending from opposite ends thereof is sealed to a glass tube 18 by threading one of the terminals 17 through an apertured brazing disc 24 and through an <PICT:1069907/C1/1> apertured metal disc 21, seating the metal disc 21 in a jig 27 adjacent to a heating coil 31, placing an open end glass tube 18, of similar coefficient of expansion to the metal disc 21, around the component 11, blowing a protective inert gas across the metal disc in the region of the terminal 17, energizing the coil 31 to heat the metal disc to a temperature at which the glass flows and the brazing material melts, the metal disc being in the high intensity region of the electromagnetic field of the coil, maintaining the heat level until a complete seal is effected between the disc and the tube and then cooling. Air is passed across the disc where it meets the tube to form an oxidizing layer thereon. To aid the sealing, pressure may be applied to the tube, such as by a weight 34. The metal disc 21 is preferably made of a metal similar to "Kovar" (Trade Mark), the brazing metal being coin silver (90% silver: 10% copper). The tube 18 is made from a borosilicate glass. Preferably the metal disc 21 has a concave outer portion in the region of the aperture. The protective atmosphere is created by the use of a gas mixture of 8% hydrogen with 92% inert gas, such as nitrogen or preferably helium. This can also be used to fill the completely sealed capsule.
