July 23, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventor JANG, Jin Bok (Suwon, KR), filed on March 13, 2013, was made available online on July 10, 2014.

The patent's assignee is Samsung Electro-mechanics Co., Ltd.

News editors obtained the following quote from the background information supplied by the inventors: "The present invention relates to a shield-can and a jig for manufacturing the shield-can.

"A case in which a mobile communications terminal such as a mobile phone, a personal digital assistant (PDA), and the like has a camera module mounted therein has more increased.

"In addition, the camera module is generally mounted on a printed circuit board, wherein the printed circuit board functions in a state in which various electronic components are mounted thereon, together with the camera module. Meanwhile, the above-mentioned electronic components are generally configured so as to form an integral module on the printed circuit board.

"However, the integral module used in a mobile communications terminal and the like may be exposed to severe electro-magnetic interference, and this electro-magnetic interference may cause the electronic components configuring the integral module to function abnormally.

"In order to solve the above-mentioned problem, a shield-can of a typical metal is used, where the shield-can forms an exterior of the camera module and serves to block the electro-magnetic interference affecting the electronic components and to protect the camera module from an external impact.

"Meanwhile, the above-mentioned shield-can is generally mounted on a printed circuit board on which the electronic components are mounted, such that a protruded portion of a solder for electrically connecting the electronic components and the printed circuit board and the shield-can may be in contact. Therefore, short between the electronic component and the shield-can may be generated by the contact between the protruded portion of the solder and the shield-can.

"Further, in the case in which the shield-can is mounted on the camera module, light reflected from an upper surface of the shield-can may interfere with light incident on a lens part of the camera module, such that an amount of the light toward the lens part may be decreased."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventor's summary information for this patent application: "An aspect of the present invention provides a shield-can capable of improving an amount of light incident on a lens part and decreasing occurrance of shorts at the time of being installed in a camera module.

"Another aspect of the present invention provides a jig for manufacturing a shield-can, capable of simultaneously forming an insulating layer and an anti-reflection layer on the shield-can.

"According to an aspect of the present invention, there is provided a shield-can, including: a plate including a circular through-hole formed therein for exposing a lens part; a plurality of side walls extended from edges of the plate and forming an inner space together with the plate; an anti-reflection layer stacked on an upper surface of the plate; and an insulating layer stacked on an inner surface of any one side wall of the plurality of side walls and at edges of inner surfaces of side walls neighboring the any one side wall, wherein the insulating layer has a band shape and is stacked on lower end portions of the inner surfaces of the side walls.

"The plate and the plurality of side walls may be formed integrally with each other and may be formed of a metal material.

"The plate may have a quadrangular shape and the plurality of side walls may be configured of first through fourth side walls extended from the plate.

"The insulating layer may be entirely stacked on a lower end portion of an inner surface of the first side wall and may only be stacked on a partial region of lower end portions of corners at which the second and third side walls and the first side wall are connected to each other in the second and third side walls.

"According to another aspect of the present invention, there is provided a jig for manufacturing a shield-can, the jig including: an upper jig including a plurality of cells formed therein, each of the plurality of cells being provided with an opening part exposing an upper surface of the shield-can; and a lower jig including a plurality of unit cells formed therein, the plurality of unit cells being provided with a shield-can coupling part corresponding to a shape of the shield-can, wherein the shield-can coupling part is provided with an open part allowing an insulating layer to be formed on an inner surface of the shield-can, and the plurality of unit cells are provided with an insulating layer forming prevention jaw protruded to the open part side in order to prevent the insulating layer from being formed on a bottom surface of the shield-can.

"The plurality of cells may be provided with a separation preventing jaw extended to the opening part side to thereby prevent the shield-can from being upwardly separated.

"Bottom surfaces of the plurality of cells may be provided with supporting wall parts extended in order to support an outer surface of the shield-can.

"The plurality of unit cells may be provided with support protrusions in order to support an outer surface of a side wall of the shield-can disposed in the open part.

"Bottom surfaces of the plurality of unit cells may be provided with an inclined surface in order to easily form the insulating layer in the shield-can.

"The upper jig may include upper and lower side wall parts extended upwardly and downwardly from an edge thereof, the lower jig may include upper and lower extending wall parts extended upwardly and downwardly from an edge thereof, and each of the lower side wall part and the upper extending wall part maybe formed so that at least one of four corners thereof has a shape different from that of other corners.
