Abstract
PURPOSE: To make possible mass production of coils which are electrically and mechanically stable by using a heater head which has a taper at its bottom face.
CONSTITUTION: When the terminal 7 of a lead is pushed to an electrode 8 with a heater head 9 being heated by current, the coat of the terminal 7 is scattered and the body of the terminal 7 is welded into the gold of an electrode 8. At that time the heated and welded part 7a is so inclined that the thickness can decrease gradually from a part 7c toward another part 7d sectionally as shown in Fig I. In the plan view the welded part 7b is crushed in a fan form as shown in Fig II. At this time the thickness of this thin part 7d can be changed by adjusting the pressure, temperature of the head 9. And it is posible to cut the thin part 7d and remove simply the residual part 7a. After that, ultraviolet hardening paint, etc. is coated in order to protect the terminal part 7.
