Abstract: There is provided an oil supply nozzle including a micro-needle, and a needle holder to which the micro-needle is inserted and fixed with an adhesive, wherein the needle holder includes a coupling hole formed to allow the needle holder to be inserted into an oil injection apparatus, and an injection hole connected to the coupling hole and having the micro-needle inserted thereinto, and the insertion hole and the coupling hole have a guide hole at a point of connection therebetween.

Abstract: Disclosed herein is a nozzle tip coupled to a nozzle header so that washing water is sprayed toward a substrate during a process of washing the substrate, the nozzle tip including: a flange having a hollow part formed therein; and a pipe body having a discharging slit formed in a front end portion thereof so as to be communicated with the hollow part of the flange.

Abstract: A camera module including a housing that includes one or more lenses which are sequentially fixed and coupled and of which the focus does not need to be adjusted; a holder assembly that is coupled to a lower end portion of the housing; and a main substrate that is coupled to a lower end portion of the holder assembly through a reflow process, wherein the holder assembly includes a holder including a housing mounting portion, and a filter mounting portion that is formed in such a manner that an internal space of the holder is sealed by an IR filter.

Abstract: Provided is a method of manufacturing a camera module, the camera module including a housing that includes one or more lenses which are sequentially fixed and coupled and of which the focus does not need to be adjusted; a holder assembly that is coupled to a lower end portion of the housing; and a main substrate that is coupled to a lower end portion of the holder assembly.

Abstract: A nonadjustable focusing type camera module includes a lens assembly having at least one lens, a lens accommodating part mounted on an upper surface of a substrate, and a barrel having an inner space in which the lens assembly is arranged along an optical axis. An upper cap having an incident hole formed in a front center thereof is fixed to the upper side of the barrel to apply pressure to the lens assembly along the optical axis. The camera module further includes an image sensor having an image forming plane on which a light passed through the lens is focused. The sensor is electrically connected to the substrate to transmit the focused image, and a filter is disposed between the lens assembly and the image sensor.

Abstract: A camera module having a ground dummy board, the camera module including: a lens holder having at least one lens; an image sensor having an image region where light passed through the lens is imaged; a board having the image sensor mounted at one side assembled to a lower surface of the lens holder; and a ground dummy board disposed on an outer surface of the board to electrically connect to ground via holes exposed to the outer surface of the board. The camera module minimally experiences electromagnetic interference and electrostatic discharge, thereby improved in electrical properties thereof.
