In a method for fabricating a surface mountable chip inductor, a spiral coil pattern is formed on a surface of a cylindrical body fabricated by mixing ferrite or ceramic powder with thermoplastic organic binder, the cylindrical body is transformed into a square-shaped body by being inserted into a square-shaped mold and pressure being applied at a certain temperature. An electric characteristic lowering problem can be prevented by forming the coil on the cylindrical body, and transforming the cylindrical body into a square-shaped body to improve surface mounting.

Method for fabricating surface mountable chip inductor

An array type multi-chip device and a fabrication method therefor form a plurality of devices of the same kind or different kinds into a single chip. The array type multi-chip device includes: an array type sintered body in which a plurality of unit devices are arranged such that internal electrodes of each of the unit devices are exposed at opposite side surfaces of the array type sintered body; glass pastes formed at portions of the side surfaces of the array type sintered body between the internal electrodes of the adjacent unit devices; external electrodes of conductive paste formed to cover the internal electrodes at the surfaces of the sintered body between the adjacent glass pastes and overlapping the glass pastes; and nickel and solder platings formed on surfaces of the external electrodes.
