Abstract
PURPOSE:To enhance the mass productivity with no application of press-in or pressing by producing the plug and the cap with the materials featuring different linear expansion coefficients. CONSTITUTION:Cap A' is made of Zn (30X10<-6>) featuring a large linear expansion coefficient, and plug B' is made of W (4.5X10<-6>) featuring a small linear expansion coefficient each. The oscillator is attached to plug B' and then connected to the lead to be then exposed under a high temperature through the baking process in order to secure an easy insertion of the plug into the cap. In this ease, the solder stuck previously to the plug flows out to ensure an assured hermetic sealing by drawing the oscillator out of a high temperature atmosphere. Thus a high production yield is obtained with no mechanical impact given to the oscillator. Instead of Zn, the signals state or in the alloy of Al, Au, Sn, Fe and Cu can be used. Also Pt and Ta can be used. Also Pt and Ta can be used singly or in the elloy in place of W.
