Method for fabricating a chip-type varistor having a glass coating layer
A ceramic chip-type device having a glass coating film and a fabricating method thereof are provided, in which a coating film having an excellent acid-resistant property is formed on the surface of the ceramic chip device. Thus, the ceramic chip-type device having a glass coating film stands an attack due to a flux at the time of reflow soldering, to thereby maintain an initial insulation resistance. The ceramic chip-type device is made of a ceramic passive device chip including a pair of external electrode terminals on either end of the ceramic chip-type device, and a glass coating film of an excellent acid-resistant property formed on the surface of a ceramic body located between the pair of external electrode terminals.
