## Title
Camera module and electronic device using same

## Abstract

A camera module includes a printed circuit board and a camera mounted to the printed circuit board. The printed circuit board further defines a at least one cut-out located near the camera.

## Background
BACKGROUND
1. Technical Field
This disclosure generally relates to camera modules, and particularly to camera modules used in electronic devices.
2. Description of Related Art
Commonly, portable electronic devices such as mobile phones use cameras typically mounted to printed circuit boards by surface mounted technology. However, the cameras may separate from the printed circuit board when an exterior force is applied to the mobile phones.
Therefore, there is room for improvement within the art



BRIEF DESCRIPTION OF THE DRAWINGS

The components in the various drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the exemplary chip card holder and electronic device using the chip card holder. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the diagrams.
FIG. 1 is an assembled view of an electronic device with a camera module.
FIG. 2 is a planar view of the electronic device of FIG. 1.
FIG. 3 is a planar view of another camera module.



DETAILED DESCRIPTION
Referring to FIG. 1, an electronic device 100 (e.g., mobile phone) includes a camera module 10. The camera module 10 includes a printed circuit board (PCB) 12 and a camera 14. The camera 14 may be mounted to the PCB 12 by surface mounted technology.
In this exemplary embodiment, the PCB 12 defines at least one cut-out 122 respectively located near the camera 14, such as located at one corner of the camera 14. Each at least one cut-out 122 may have different shapes, such as L-shaped. When an exterior force F bumps the electronic device 100, the PCB 12 may be distorted, generating a stress. As the PCB 12 defines the at least one cut-outs 122, the stress generated by the PCB 12 will be concentrated on the at least one cut-out 122 to protect the camera 14 from separating from PCB 12. In the exemplary embodiment shown in FIG. 3, an electronic device 200 has a PCB 22 defining four at least one cut-out 222, each respectively located at one corner of a camera 24.
Referring to FIGS. 1 and 2, the camera module 10 may further include a strengthening board 16 attached (e.g., adhered) to the PCB 12 to strengthen the PCB 12. In this exemplary embodiment, the strengthening board 16 is located at one side of the camera 14 opposite to the at least one cut-out 122.
It is to be further understood that even though numerous characteristics and advantages of the exemplary embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
