A flexible circuit board for soldering image sensors

Abstract

The invention discloses a flexible circuit board for welding an image sensor, which includes a first area and a second area arranged in sequence, and the second area includes a central part at its center and welded with the image sensor, and a central part around the central part. The frame portion is provided with evenly distributed coil groups, and the central portion and the frame portion are connected to the edge of the second area through elastic arms. The flexible circuit board of the present invention can be used to install coils, and at the same time provide flexibility for the focus and anti-shake movement of the image sensor, can simplify the structure of the camera module, and greatly reduce its volume.

Description

technical field

[0001] The invention relates to accessories for camera modules, in particular to FPC soft boards therein. Background technique

[0002] With the continuous update and improvement of mobile terminal products, its camera effect is basically comparable to that of a card machine, so compared with a camera, people are more willing to use a tablet computer or a smart phone to realize the camera function.

[0003] In order to enhance the camera function of mobile phones and other products, manufacturers generally make various improvements to the voice coil motor, adding functions such as auto focus and optical image stabilization to achieve the best camera effect. But at present, all kinds of motors have their own shortcomings. For example, in the process of voice coil motor, the image sensor in the camera module is difficult to prevent dust, which may easily lead to scrapping. In addition, the motor needs a matching lens to form a camera module, so the design of t...

Embodiment Construction

[0012] The structural principle of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0013] figure 1 , figure 2 The flexible circuit board for welding image sensor of the present invention is given, it is divided into two areas, one is figure 1 The first area 1 is located below, and the other is the second area 2 located above. The first area 1 is used to conduct the coil 3 in the second area 2 and communicate with the motherboard platform, and the second area 2 is used for soldering. An image sensor electrically connects the coil 3 to the first area 1 .

[0014] Wherein, the second area 2 has a central part 21 located at the center thereof, on which there are welding feet 22 for welding with the image sensor, and the surrounding of the central part 21 is called a frame part 23, and coils are evenly distributed on the frame part Group. The coil group includes at least two or more coils 3, the example given in th...
