BACKGROUND OF THE PRESENT INVENTION

Field of Invention

The present invention relates to camera module, and more particularly to a camera module with compression-molded circuit board and the manufacturing method thereof.

Description of Related Arts

With the rapid development of the technology and the improvement of peoples' living standard, more and more smart electronic device have been used in various field and daily life. The smart electronic device can be seen everywhere. The smart device comprises all kinds of electrical parts, optical products, wherein the camera module plays one of the most important role.

All smart devices are developed in the direction of being thinner and having higher performance. Accordingly, high-pixel, high quality imaging and ultra-thin become a demand of the camera module.

Conventional camera module, made by COB (Chip On Board) technology, usually comprises at least a rigid-flex board, a photosensitive chip, a lens holder, a driving motor, and an optical lens. All electrical and electronic parts are arranged on the surface of the circuit board without overlapping with each other. With the demand of high-pixel, high image quality and high performance, the number of electrical and electronic components on the circuit board is increasing, and the size of the chip is increasing for accepting more resistors, capacitors and driven parts, resulting that the overall size of the electrical and electronic components getting bigger and bigger, the difficulty in assemble being more and more, and the size of the camera module being bigger and bigger too.

Smart phone, for example, is updating models from day to day, and the camera module is developed accordingly. The development of the smart phone is mainly focused in two directions. One is to provide more functions and more stable performance for the smart phone. The other is to improve the appearance and thickness of the smart phone. It is apparent that, the photoelectric properties of the camera module greatly affects its image quality, such as photo taking or video taking. On the other hand, according to the arrangement of the conventional smart phone, the camera module is parallelly installed in the smart phone, and therefore, the thickness of the camera module greatly affects and determines the thickness of the smart phone, while the projection area of the camera module substantially affects the width of the smart phone. One skilled in the art would find that the main factor that limits the ultra-thinness development of the smart phone is the camera module to be used. It is so difficult for the camera modules applied to the current smart phones to have a balanced coordination between good performance and compact overall size thereof.

It is apparent that, on the basis of conventional manufacturing and assembling technologies of the camera module, the requirements of the high performance and ultra-thinness in size of the camera module is irreconcilable contradiction.

The implementation of a camera module relies on all related factors. The photosensitive performance including the pixel and quality of the image taken by the camera module is related to the electrical and electronic components and optical elements. The size, shape, quality and other physical properties of the camera module is related to the manufacturing process, the assembly method, the manufacturing material to be used, and etc. How to more reasonably and appropriately manufacture and assemble more and more components to provide a camera module with outstanding performance like high-pixel, high image quality and etc., while fulfilling the requirement of lighter and thinner in size, is a problem remained to be solved.

Referring to FIGS. 1 to 3, a camera module according to a preferred embodiment of the present invention is illustrated. The camera module comprises a frame 10, a circuit board 20, a light-sensitive sensor such as a photosensitive chip 30, an optical lens 40, and a driver such as a motor 50. One skilled in the art can understand that without the motor 50, the camera module can be embodied as a fixed-focal camera module.

As shown in the figures, the photosensitive chip 30 is provided on the circuit board 20. The frame 10 is installed on the circuit board 20.
