Abstract
A print head of an ink-jet printer including a main chip area having at least one ink jetting portion disposed on a substrate to jet ink, and at least one bonding pad connected with a corresponding lead end of a wiring of a circuit part to control the ink jetting portion; and a scribe lane area disposed around the main chip area and forming a cutting region in which the main chip area is divided from main chip areas of other print heads by cutting, the scribe lane area having a damping pattern portion formed to be electrically and physically isolated from the main chip area and the substrate.
Claims24
A print head of an ink-jet printer, comprising:
- a main chip area having at least one ink jetting portion disposed on a substrate to jet ink, and at least one bonding pad connected with a corresponding lead end of a wiring of a circuit part to control the ink jetting portion;
- and
- a scribe lane area disposed around the main chip area and forming a cutting region in which the main chip area is divided from main chip areas of other print heads by cutting, the scribe lane area having a damping pattern portion formed to be electrically and physically isolated from the main chip area and the substrate.
A head chip for an ink-jet printer, comprising:
- a main chip area having at least one ink jetting portion disposed on a substrate;
- a scribe lane area disposed around the main chip area and forming a cutting region in which the main chip area is divided from main chip areas of other print heads;
- and
- a damping portion on the scribe lane area of the main chip area;
- wherein the damping portion electrically and physically protects the head chip in the main chip area.
A head chip for an ink-jet printer, comprising:
- a main chip area having at least one ink jetting portion disposed on a substrate;
- a scribe lane area disposed around the main chip area and forming a cutting region in which the main chip area is divided from main chip areas of other print heads by cutting;
- and
- a damping portion on the scribe lane area of the main chip area;
- wherein the damping portion electrically insulates and mechanically reinforces an outer area of the head chip, preventing short circuits between the substrate and wire leads coming onto the head chip.
A head chip for an ink-jet printer, comprising:
- a main chip area having at least one ink jetting portion disposed on a substrate;
- a scribe lane area disposed around the main chip area and forming a cutting region;
- and
- a damping portion on the scribe lane area of the main chip area;
- wherein the damping portion comprises metal, and efficiently removes heat generated from the main chip area during a printing process.
