Abstract: The present invention relates to a gap supporter for a printed circuit board, and a package including a gap supporter for a printed circuit board and an insulation sheet coupled thereto. A gap supporter for a printed circuit board includes a fixed body part which has a metal thin-film formed on the surface of the lower end thereof, and is fixed to one surface of the printed circuit board by soldering of the metal thin-film; a clamping groove formed in a groove shape on the fixed body part, and having an insulation sheet inserted and clamped thereto to protect an element on one surface of the printed circuit board; and an anti-separation part formed on the other end of the fixed body part so as to be defined by the clamping groove, so as to fix the insulation sheet and prevent the insulation sheet from being separated.

Abstract: Disclosed is a method for manufacturing a substrate gap supporter. The method includes: a first step of forming metal foils on both sides of an insulating plate; a second step of etching the metal foils to expose the insulating plate so that a plurality of stripes are arranged on both sides of the insulating plate in parallel at constant intervals, wherein the stripes expose the insulating plate at constant widths; and a third step of cutting in direction in parallel with the stripes and in direction in vertical with the stripes along one edges of the stripes to complete the gap supporter.

Abstract: The substrate gap supporter (30) according to one embodiment of the present invention comprises a body (31) having a hexahedron shape and made of an insulator, metal foils (32a) and (32b) installed on opposite side surfaces of the body (31) to expose the upper portions of both side surfaces and cover the lower portions of both side surfaces, and a substrate (210) attached to the bottom surface of the body (31). According to the present invention, the gap supporter can be made through an automated process, thus precisely controlling size. Since the gap supporter is attached to the surface of the substrate, there is little possibility for a height difference to occur. And also, because the gap supporter can be installed in an automated process, it is suitable for a mass production process.

Abstract: Method for making a minute product by using laser beam. A workpiece is mounted on a mounting device. The laser beam is irradiated to a pre-selected portion of the workpiece for ablation. The space formed during the ablation is filled with filler. The other portion of the workpiece is ablated for making the workpiece to have a predetermined shape. The filler is removed from the shaped workpiece to provide the minute product.
