ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a glazing covered ferrite core electrode terminal. More particularly, the present invention relates to a glazing covered ferrite core electrode terminal of a surface mounting inductor.
A conventional ferrite core electrode terminal is coated by a silver paste. Since a surface of the ferrite core electrode terminal has a plurality of gas spacings, some gas spacings will remain between the ferrite core electrode terminal and the silver paste. The silver paste will release from the ferrite core electrode terminal under high temperatures. Furthermore, the surface of the silver paste will be uneven so that a further soldering result will be poor.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a glazing covered ferrite core electrode terminal which has a glazing covered layer to provide a smooth surface.
Another object of the present invention is to provide a glazing covered ferrite core electrode terminal which has a glazing covered layer disposed between a silver paste layer and a ferrite core so that an electroplating solution will not enter a surface of the ferrite core.
Another object of the present invention is to provide a glazing covered ferrite core electrode terminal which has a glazing covered layer, a silver paste layer, a nickel plated layer, a solder plated layer, and a solder paste layer to reinforce a ferrite core.
