Abstract:
A method for manufacturing an image drum and an image drum are provided to easily manufacture the image drum by bonding a chip to a flexible PCB(Printed Circuit Board) and putting the flexible PCB around a drum body to improve printing quality. A flexible PCB(120) on which a plurality of ring electrodes(125) is formed is provided. The ring electrodes are electrically insulated from one another and arranged in parallel. A control unit(130) is bonded to the surface of the flexible PCB. The control unit independently applies voltages to the respective ring electrodes. Contact ends of the flexible PCB, which are respectively adjacent to both ends of the ring electrodes, come into contact with each other. The ring electrodes form a single ring structure. The ring electrodes are electrically connected or disconnected.
Abstract:
An image drum and a method for manufacturing the image drum are provided to form connecting parts for connecting ring electrodes with a terminal of a control chip without using laser precision machining to reduce the manufacturing cost and improve productivity. A cylindrical drum body(110) is prepared. A PCB(Printed Circuit Board)(300) including a control chip for applying a voltage to an image drum and a terminal connected to the control chip is bonded to the inside of the drum body in such a manner that the terminal is exposed to the outside of the drum body. A sacrificial structure is formed on the terminal. A region of the PCB other than the sacrificial structure is coated with an insulating material. The sacrificial structure is removed to form connecting holes. The connecting holes are filled with a conductive material. A plurality of ring electrodes is formed in parallel on the drum body and the exposed portion of the PCB in such a manner that the ring electrodes come into contact with the conductive material.

A micromirror actuator having a micromirror, which is operative using an electrostatic force with a low voltage and wherein an electrostatic force opposite to the driving force of the micromirror is blocked, and a method for manufacturing the same, are provided. The micromirror actuator includes a substrate, a trench in which at least one electrode is formed, supporting posts installed at opposite sides of the trench, a torsion bar supported by the supporting posts, and the micromirror including a driving unit which faces the trench when the micromirror is in a horizontal state, and a reflecting unit, which is elastically rotated about the torsion bar, to reflect an optical signal. The actuator also includes a shielding electrode installed to face the reflecting unit when the micromirror is in a horizontal state and to block an electrostatic force occurring between the reflecting unit and the electrode.

PURPOSE: A method for manufacturing a structure of MEMS(Micro Electro Mechanical System) for preventing stiction is provided to prevent micro-structures from being sticked to a substrate. CONSTITUTION: A substrate(100) is prepared. A removable stiction preventing layer(101) used in a dry-etching is formed on the substrate(100). A removable sacrificial layer(103) used in a wet-etching is then formed on the stiction preventing layer(101). A post hole is formed to expose the surface of the substrate(100) by selectively etching the stiction preventing layer(101) and the sacrificial layer(103). A structure layer(109) is formed on the resultant structure including the post hole. An SOG(Silicon On Glass), polysilicon, or photoresist is used as the stiction preventing layer(101). Also, the sacrificial layer(103) is one selected from group consisting of PSG(Phosphosilicaglass), SiO2, Cu, Fe, Mo, Ni, Cr, and TEOS(Tetra Ethyl Ortho Silicate) glass.
