Abstract
Abstract A chip electronic device wherein an electronic element such as an inductor and capacitor, and terminals are covered with a resin housing. Plated lower surfaces and edges of the terminals show on a bottom and sides of a housing respectively. The lower surfaces of the terminals are soldered onto conductive patterns of a printed wiring board, and fillets of solder are formed at the edges of the terminals.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
80 words
A chip electronic device with a resin housing comprising: an electronic element; a terminal which is formed by punching a strip into a specified shape having at least one protruded edge and plated, the terminal being electrically connected with an electrode of the electronic element; and a resin housing which houses the electronic element and the terminal such that a plated lower surface and a plated edge of the terminal show on a bottom and a side of the housing.
Claim 2
Dependent Claim
80 words
A chip electronic device with a resin housing comprising: an electronic element; a terminal which is formed by punching a strip into a specified shape having at least one protruded edge and plated, the terminal being electrically connected with an electrode of the electronic element; and a resin housing which houses the electronic element and the terminal such that a plated lower surface and a plated edge of the terminal show on a bottom and a side of the housing.
Claim 3
Dependent Claim
31 words
A chip electronic device according to claim 1, wherein said at least one protruded edge extends outward from the terminal and is flush with an exterior surface of said resin housing.
Claim 4
Dependent Claim
84 words
A manufacturing process of a chip electronic device with a resin housing comprising: forming a terminal by punching a strip into a specified shape which has a protruded edge; plating the formed terminal; mounting an electronic element onto the terminal; molding a resin into a housing which houses the electronic element and the terminal such that a plated lower surface and a plated edge of the terminal show on a bottom and a side of the housing; and separating the terminal from the strip.
Claim 5
Dependent Claim
84 words
A manufacturing process of a chip electronic device with a resin housing comprising: forming a terminal by punching a strip into a specified shape which has a protruded edge; plating the formed terminal; mounting an electronic element onto the terminal; molding a resin into a housing which houses the electronic element and the terminal such that a plated lower surface and a plated edge of the terminal show on a bottom and a side of the housing; and separating the terminal from the strip.
Claim 6
Dependent Claim
31 words
A process according to claim 3, wherein said step of molding further includes a step of: forming said side of the resin housing flush with said plated edge of the terminal.
