The disclosure relates to a structure which may reduce a size of a camera module.
In order to meet users' demand for convenience, ease of portability of electronic devices, developments in miniaturization and integration of electronic devices are continuously being conducted.
In particular, since inner spaces of electronic devices are limited, developments in miniaturization and integration of camara modules included in electronic devices are also being conducted. Typically, a camara module may have a layered structure in which components such as a lens assembly, a housing, an image sensor, a printed circuit board (PCB), a metal plate, a multi-layer ceramic condenser (MLCC) are layered in sequence.
According to related-art technologies, a separate space for mounting a MLCC is required, and hence, there is a problem that a size of a camera module increases as large as the space.
According to related-art technologies, due to the presence of a separate space for mounting a MLCC, there is a problem that space utilization in a camera module is degraded.
In a camera module according to an example embodiment of the disclosure, the camera module may include: a rigid printed circuit board (RPCB); a metal plate coupled to a lower surface of the RPCB and having one or more holes formed therein; a multi-layer ceramic condenser (MLCC) disposed in the one or more holes under the RPCB; and an image sensor disposed on the metal plate, wherein a height of the MLCC may be less than a height of the metal plate with reference to a lower surface of the RPCB.
In a structure of a camera module, the structure may include: a flexible printed circuit board (FPCB), a rigid printed circuit board (RPCB) coupled to a lower surface of the FPCB and having one or more first holes formed therein, a metal plate coupled to a lower surface of the RPCB and having one or more second holes formed in areas corresponding to the first holes, respectively, a multi-layer ceramic condenser (MLCC) disposed in the first holes and the second holes under the FPCB, and an image sensor disposed on the metal plate, wherein the MLCC may be disposed in at least one space of spaces formed through the first holes and the second holes.
According to various example embodiments of the disclosure, a different structure of a camera module may be utilized, such that a separate space for mounting a MLCC may not be required and space utilization may be enhanced.
According to various example embodiments of the disclosure, a MLCC may be disposed in the proximity of an image sensor, such that signal characteristics of the image sensor may be maintained.

It should be appreciated that various embodiments of the disclosure and the terms used therein are not intended to limit the technological features set forth herein to particular embodiments, and include various changes, equivalents, or alternatives for a corresponding embodiment. With regard to the description of the drawings, similar reference numerals may be used to refer to similar or related elements. It is to be understood that a singular form of a noun corresponding to an item may include one or more of the items, unless the relevant context clearly indicates otherwise. As used herein, each of such phrases as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B, or C,” “at least one of A, B, and C,” and “at least one of A, B, or C,” may include one or all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as “1st” and “2nd,” or “first” and “second” may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (for example, importance or order). It is to be understood that if an element (for example, a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with,” “coupled to”, “connected with”, or “connected to” another element (for example, a second element), the element may be coupled with another element directly (e.g., wiredly), wirelessly, or via a third element.
As used herein, the term “module” may include a unit implemented in hardware, software, or firmware, or any combination thereof, and may interchangeably be used with other terms, for example, “logic,” “logic block,” “part,” or “circuitry”. A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC).
Various embodiments of the disclosure may be implemented as software (for example, the program 140) including one or more instructions that are stored in a storage medium (for example, internal memory 136 or external memory 138) that is readable by a machine (for example, the electronic device 101). For example, a processor (for example, the processor 120) of the machine (for example, the electronic device 101) may invoke at least one of the one or more instructions stored in the storage medium, and execute it. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a compiler or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Wherein, the “non-transitory” storage medium is a tangible device, and may not include a signal (for example, an electromagnetic wave), but this term does not differentiate between a case where data is semi-permanently stored in the storage medium and a case where the data is temporarily stored in the storage medium.
According to an embodiment, a method according to various embodiments of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (for example, compact disc read only memory (CD-ROM)), or may be distributed (for example, downloaded or uploaded) online via an application store (for example, Play Store™M), or between two user devices (for example, smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.
According to various embodiments, each component (for example, a module or a program) of the above-described components may include a single entity or multiple entities, and some of the multiple entities may be separately disposed in other components. According to various embodiments, one or more of the above-described components or operations may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (for example, modules or programs) may be integrated into a single component. In such a case, the integrated component may still perform one or more functions of each of the plurality of components in the same or similar manner as they are performed by a corresponding one of the plurality of components before the integration. According to various embodiments, operations performed by the module, the program, or another component may be carried out sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be executed in a different order or omitted, or one or more other operations may be added.
While the disclosure has been illustrated and described with reference to various example embodiments, it will be understood that the various example embodiments are intended to be illustrative, not limiting. It will be further understood by those skilled in the art that various changes in form and detail may be made without departing from the true spirit and full scope of the disclosure, including the appended claims and their equivalents.
