AI Technical Summary
Conventional camera module manufacturing processes are inefficient due to the use of epoxy resin, which requires a separate oven process for curing, leading to long processing times and potential optical alignment errors during the assembly of lens and image sensor modules.
The camera module and manufacturing device utilize a laser solder jetting method to quickly and easily assemble the housing and substrate by melting solder in the assembly gap between the housing and the printed circuit board, eliminating the need for epoxy curing and reducing alignment errors.
This approach simplifies the manufacturing process, stabilizes camera module quality, significantly shortens processing time, and reduces optical alignment errors, enabling faster and more precise assembly of camera modules.

Abstract
Description
Camera modules and camera module manufacturing equipment
[0001] The present invention relates to a camera module and a camera module manufacturing device, and more particularly, to a camera module and a camera module manufacturing device that can quickly and easily assemble a camera module by joining a housing and a substrate by a laser solder jetting method on the side of a camera module equipped with a solder ring.
[0002] Recently, mobile devices such as cell phones and laptops are equipped with camera modules equipped with image capture devices such as CCD image sensors or CMOS image sensors.
[0003] A conventional method for manufacturing a camera module includes a substrate, an image sensor disposed on the substrate, a housing assembly coupled to an upper surface of the substrate, a lens accommodated in the housing assembly, and a curable resin disposed between the upper surface of the substrate and the housing assembly, wherein the housing assembly is pressed toward the substrate while being disposed in the curable resin before the curable resin is cured, thereby performing focusing.
[0004] The housing assembly can be actively aligned with the optical axis of the lens and the optical axis of the image sensor during the pressing process toward the substrate.
[0005] At this time, the curable resin uses epoxy that is cured by ultraviolet rays (UV).
[0006] Since epoxy materials require pre-curing and then final curing (thermal curing), a separate oven process is required, which takes a long time. In addition, epoxy management requires frozen storage, which makes it difficult to handle in terms of management.
[0007] The optical axis alignment (focusing) of the lens and image sensor is performed using active alignment equipment, and the housing assembly is pressed toward the substrate so that the lens approaches the image sensor and is focused. However, the conventional camera module manufacturing method performs a process of curing epoxy by irradiating ultraviolet rays after performing active alignment. If there is a slight movement from the time of ultraviolet irradiation to the time when the epoxy is completely cured, the alignment state of the lens and the image sensor may change slightly, and the lens and the image sensor may not be in focus.
[0008] Therefore, research is ongoing on ways to easily and quickly assemble the lens module and substrate to reduce optical axis alignment errors in the camera module.
[0009] The purpose of the present invention is to provide a camera module and a camera module manufacturing device that can quickly and easily assemble a camera module by joining a housing and a substrate using a laser solder jetting method on the side of a camera module equipped with a solder ring.

[0013] A housing having one or more solder pins that are bonded to the upper surface of the printed circuit board and protrude downward by a certain length;
[0014] When inserted into the above soldering hole, the assembly gap, which is the space created on the side; and
[0015] A joint is formed by irradiating a laser into the assembly gap to melt the solder and join the housing and the printed circuit board.
[0016] A camera module manufacturing device according to the features of the present invention,
[0017] A printed circuit board having one or more soldering fixing holes formed at regular intervals and soldering of a fixed length inserted and joined into each of the soldering fixing holes, an image sensor chip mounted on the printed circuit board and detecting light as an electrical signal, and a camera module in which, when each of the solder pins is vertically inserted into each of the soldering holes, an assembly gap is created on the left and right sides of the housing and the printed circuit board, respectively;

[0039] As illustrated in FIGS. 1, 2, and 6, a camera module (100) having a soldering according to an embodiment of the present invention includes a printed circuit board (110) having a circuit pattern formed thereon, an image sensor chip (120) mounted on the printed circuit board (110), a housing (130) mounted on the printed circuit board (110) by metal bonding to seal the image sensor chip (120), a lens barrel (140) coupled to the upper portion of the housing (130) to collect light, a soldering (150) for fixing the housing (130) to the printed circuit board (110), and a camera frame (160) for mounting the printed circuit board (110) and the housing (130) therein.
[0040] The lens barrel (140) is at least one lens and can implement various lenses that can implement a camera.
[0041] The housing (130) has an open top and includes a lens and an IR filter (131) mounted in the internal space, and the lens and the IR filter (131) may be a single optical component assembled into the housing (130).
[0042] The image sensor chip (120) includes a control device that performs active alignment by photographing an inspection chart having a plurality of patterns formed thereon to obtain a chart image, comparing the second center point to determine whether they match, and determining that the optical axis of the lens and the optical axis of the image sensor chip substantially match when the deviation of the second center point falls within a reference range.
[0043] The printed circuit board (110) includes electrode terminals connected to the electrode pads of the image sensor chip (120) by wires outside the area where the image sensor chip (120) is mounted. The electrode pads of the image sensor chip (120) and the electrode terminals of the printed circuit board (110) are bonded by wires.
[0044] On the upper surface of the printed circuit board (110), a plurality of soldering fixing holes (111) are vertically penetrated to the soldering fixing holes (111) at regular intervals.
[0045] As shown in Fig. 3, the printed circuit board (110) is joined by inserting a solder (150) of a certain length into each soldering fixing hole (111).
[0046] The housing (130) has a solder pin (132) of a certain length protruding from one side of the lower surface.
[0047] The solder pin (132) is a member made of metal for mounting the housing (130) to the printed circuit board (110), and is formed with a constant length in the downward direction on one side of the lower end of the housing (130), and the number of solder pins corresponds to the number of soldering (150).
[0048] The solder pin (132) protrudes longer than the lower end of the housing (130).
[0049] The solder ring (150) has a cylindrical flange portion (151), a column portion (152) extending downward from the flange portion (151) and having a diameter smaller than the diameter of the flange portion (151) and having a constant length, and a hole (153) of a constant size is vertically penetrated from the upper surface of the flange portion (151) to the lower surface of the column portion (152).
[0050] As illustrated in FIG. 4, the flange portion (151) may include a first melting portion (151a) formed on the outer side located in the assembly gap (133) and melted by direct contact with the laser, and a second melting portion (151b) formed on the inner side opposite the outer side and melted by transferring heat from the first melting portion (151a).
[0051] Each soldering (150) can be fixed by fitting into each soldering fixing hole (111) of the printed circuit board (110).
[0052] The housing (130) is fixed by inserting the solder pin (132) into the hole (153) of the soldering (150) of the printed circuit board (110).
[0053] As illustrated in FIG. 5, the camera module (100) of the embodiment of the present invention includes a joint portion in which an assembly gap (133), which is a space created on the side of a housing (130) and a printed circuit board (110), is formed when a solder pin (132) is inserted vertically downward into a hole (153) of soldering (150), and a laser is irradiated into the assembly gap (133) to melt the soldering and join the housing and the printed circuit board.
[0054] Soldering (150) is a joining method that uses molten solder with a melting point of less than 450°C to spread the solder across the entire joining interface by utilizing the capillary phenomenon in the assembly gap (133) between two joining metal surfaces without melting the base metal.
[0055] Soldering (150) is a process in which the heat energy of a laser beam is applied to the solder portion in a non-contact manner and the solder is melted due to the absorbed heat energy, thereby forming a joint.
[0056] A key advantage of laser beam soldering (150) is that the laser beam, the heat source, can be precisely aimed at the work target, minimizing heat loss to surrounding components. Furthermore, preheating is not required when working with large components, and rapid heating and cooling enable the creation of precise joint structures with improved mechanical properties.

[0090] The first laser irradiation device (300) includes a second laser beam generation unit and a second laser beam irradiation unit.
[0091] Hereinafter, since the first laser irradiation device (300) and the second laser irradiation device (400) are identical components, for the convenience of explanation, the expressions “first” and “second” in the overlapping first laser beam generation unit (310), first laser beam irradiation unit (320), second laser beam generation unit (410), and second laser beam irradiation unit (420) are omitted and are described as laser beam generation unit and laser beam irradiation unit.
[0092] The laser beam generating unit (310, 410) includes a laser diode module (311, 411) that generates a laser beam and a power supply unit (312, 412) for supplying power to the laser diode module (311, 411).
[0093] The laser beam irradiation unit (320, 420) includes a lens assembly (321, 421), a focusing lens (322, 422), and a nozzle unit (323, 423).
[0094] The lens assembly (321, 421) is composed of a plurality of lenses, including a collimation lens that converts a laser beam in the form of a diffuse beam emitted from a laser beam generator (310, 410) into a form of a parallel beam.
[0095] The nozzle section (323, 423) can irradiate the laser beam emitted from the laser beam generating section (310, 410) through the lens assembly (321, 421) and the condenser lens (322, 422) in sequence to the upper housing (130) and the assembly gap (133) of the lower printed circuit board (110) from the side of the camera module (100).

[0099]
[0100] Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 9 and 10.
[0101] FIG. 9 is a drawing showing the relationship between a control device according to an embodiment of the present invention and a peripheral device connected thereto, and FIG. 10 is a block diagram briefly showing the internal configuration of a control device according to an embodiment of the present invention.
[0102] A control device (500) according to an embodiment of the present invention includes an active alignment control unit (531) and a laser device control unit (532).
[0103] The communication unit (510) can be electrically connected to the image sensor chip (120), the first driving motor (217), the second driving motor (228), the first laser irradiation device (300), and the second laser irradiation device (400) to provide a communication interface to transmit and receive data communication.
[0104] The active alignment control unit (234) generates a driving signal and transmits it to the first driving motor (217), and controls the first arm (219a) and the second arm (219b) coupled to the first moving block unit (214) to descend by rotating the first screw (213) according to the driving of the first driving motor (217).
[0105] The solder pin (132) of the housing (130) mounted on the first arm (219a) and the second arm (219b) is inserted vertically downward into the hole (153) of the soldering (150) of the printed circuit board (110).
[0106] An inspection chart (not shown) is placed on the upper part of the lens, and the inspection chart forms a pattern for a spatial frequency response (SFR) inspection at the center and each corner. Here, the SFR inspection analyzes the frequency component of the edge part of the pattern and determines the resolution based on the size of the high-frequency component value. Since this SFR inspection is a method that is generally and widely used to inspect the resolution of a camera module (100), a detailed description of this inspection method is omitted.
[0107] The image sensor chip (120) captures an inspection chart on which a plurality of patterns are formed to obtain a chart image.
[0108] The active alignment control unit (531) performs the function of aligning the X, Y, and R axes relative positions of the lens and the image sensor chip (120).
[0109] The active alignment control unit (531) receives a second chart image of an inspection chart from an image sensor chip (120) through a communication unit (510), stores it in a storage unit (520), extracts the second center point of the second chart image and the first center point of the first chart image of a preset inspection chart located above the lens, and compares the second center point with the first center point to determine whether they match.
[0110] The active alignment control unit (531) generates a driving signal and transmits it to the first driving motor (217), and controls the first arm (219a) and the second arm (219b) coupled to the first moving block unit (214) to rise and fall by rotating the first screw (213) according to the driving of the first driving motor (217).
[0111] Accordingly, the active alignment control unit (531) extracts the second center point of the second chart image and the first center point of the first chart image of the preset inspection chart located on the upper part of the lens, compares the second center point with the first center point, periodically determines whether they match, and aligns the X, Y, and R axis positions of the image sensor chip (120) so that the second center point and the first center point match.
[0112] The active alignment control unit (531) determines that the optical axis of the lens and the optical axis of the image sensor substantially coincide when the deviation between the first center point and the second center point falls within the reference range, and performs active alignment of the optical axis of the lens and the optical axis of the image sensor chip (120). The present invention is not limited thereto, and the active alignment control unit (531) may also perform active alignment by driving the second driving motor (228) to move the substrate jig (225) in the horizontal direction.
[0113] After performing active alignment, the laser device control unit (532) generates a power drive signal and transmits it to the second laser beam generating unit (410), and the laser is irradiated into the assembly gap (133) formed on the left side of the camera module (100) so that the soldering (150) melts and the housing (130) and the printed circuit board (110) are joined, and the laser is irradiated into the assembly gap (133) formed on the right side of the camera module (100) so that the soldering (150) melts and the housing (130) and the printed circuit board (110) are joined.
[0114] The camera module (100) can be easily and quickly assembled with a lens module and a substrate by melting solder (150) by irradiating a laser from the side of the camera module (100) to join the housing (130) and the printed circuit board (110), thereby simplifying the process, stabilizing quality, and shortening the time, thereby reducing errors in optical alignment (focusing).
