Abstract:
PURPOSE: An electronic compass package with a fluxgate device mounted by a flip bonding method and a manufacturing method thereof are provided to reduce the size of an electronic compass package using a bump ball. CONSTITUTION: An electronic compass package with a fluxgate device mounted by a flip bonding method comprises bumps. The bumps are formed in electric terminals of a x-axis fluxgate element(500), a y-axis fluxgate element(400), and a z-axis flux gate element(200). The bump is mounted in ball grid array. The bumps are electrically connected to each electric terminal of ASIC driver elements(300). The x-axis and y-axis fluxgate elements are horizontally installed on the top of the ASIC driver elements.
Abstract:
PURPOSE: An electronic compass enclosed in a housing structure is provided to solve a problem that a z-axis flux gate device is fallen due to weak impact which is generated when the z-axis flux gate device is tilted. CONSTITUTION: An electronic compass having housing structure enclosed therein is comprised of a thin film type 3-axes fluxgate and a housing(100). The magnetic field from three directions is detected through the thin film type 3-axes fluxgate. The housing accommodates an x-axis flux gate device(250), an y-axis flux gate device(270), a z-axis flux gate device(210), and ASIC driver component(230). The ASIC driver component runs each flux gate device. A cavity having a certain level is recessed in the housing.

PURPOSE: An electron compass with a flux gate device, and a manufacturing method thereof are provided to improve the reliability of a bonding pad thin film. CONSTITUTION: An electron compasses with a flux gate device comprises follows. An z-axis fluxgate sensor is equipped on a single board with fixed size. The first electrical terminal of a single board and a terminal which is arranged on the z-axis fluxgate sensor are electrically connected with one another. A base substrate(210) of the electron compass is vertically mounted on a z-axis flux gate device(100). The first electrical terminal with fixed length is formed at end of a single board.
Abstract:
A method for manufacturing a package on a camera module by using a PCB(Printed Circuit Board) panel and the PCB panel thereof are provided to lower manufacturing cost by removing an outer shape processing process and increase manufacturing efficiency per PCB panel by increasing cutting precision. One unit substrate array is formed by vertically arranging a plurality of unit boards including a circuit pattern on a PCB. A PCB panel is manufactured by horizontally arranging the unit substrate arrays. A part between the neighboring unit substrate arrays is cut by using a dicing saw(S130). A package array is formed by mounting the part for forming a camera module on each unit substrate of the PCB panel(S160). Each package is separated by cutting the neighboring packages(S170).
Abstract:
PURPOSE: An ultra thin optical input device is provided to apply an ultra input device to various portable devices by reducing the thickness of an optical input device. CONSTITUTION: An optical function unit is inserted inside a cover and includes an optical filter(122) which selectively penetrates light according to wavelength. A lens structure(130) penetrates light which penetrating the optical filter and performs a light condensing function. A light blocking unit(140) blocks the light which penetrates the lens structure. The circuit board includes an optical sensor(152) sensing the light.
Abstract:
PURPOSE: A small sized camera module is provided to simply insert a lens assembly into a housing holder by means of a groove protrusion, thereby simplifying a manufacturing process to reduce manufacturing costs and manufacturing time. CONSTITUTION: A lens assembly(120) is loaded on a substrate. A housing holder(130) is mounted on the substrate. A penetration opening is formed in the housing holder and part of the lens assembly is inserted into the penetration opening to support the lens assembly. A protrusion part is formed in an end of the lens assembly.
