Printed circuit boards, camera modules and mobile terminals

Abstract

The invention provides a printed circuit board. The printed circuit board comprises a first bonding pad set and a second bonding pad set, wherein the first bonding pad set comprises a first functional bonding pad and a second functional bonding pad, the second bonding pad set comprises a first bonding pad, a second bonding pad and a third bonding pad, the first bonding pad is connected with the first functional bonding pad through first routing, the second bonding pad is connected with the second functional bonding pad through second routing, the third bonding pad is arranged between the first bonding pad and the second bonding pad, and the third bonding pad is connected with a first signal path; the first bonding pad and the third bonding pad are connected through a first resistor; and the second bonding pad and the third bonding pad are connected through a fourth resistor. Moreover, the invention also provides a shooting module using the printed circuit board and a mobile terminal using the shooting module. The printed circuit board can realize PCB sharing among shooting modules with different pixels.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a printed circuit board, a camera module and a mobile terminal. Background technique [0002] At present, high-definition camera modules have been more and more widely used in mobile terminals such as smart phones and tablet computers. With the improvement of the imaging quality of the built-in camera module of the mobile terminal, people no longer need to carry a relatively bulky digital camera in daily travel, but can directly use the camera module built in the mobile terminal to complete high-quality image shooting. In order to enrich the product models of mobile terminals, a popular mobile terminal product may include many different models, and the price ranges of each model of mobile terminals are different, so as to meet the needs of different consumer groups. Usually, in order to control the production cost of different models of products and reflect the performance d...

Problems solved by technology

[0003] However, for camera modules with different pixels, although they have the same component packaging structure, the signal sequence of the component pins is not exactly the same, so that in the manufacturing process of different pixel products, they need to be designed separately. Printed Circuit Board (PCB), and use different product lines to achieve component placement and debugging

Therefore, since PCBs cannot be shared between products with different pixels, it will undoubtedly increase the production cost and production cycle of the product, resulting in unnecessary waste of manpower and material resources; at the same time, different product models use different PCBs, which will also increase inventory risks.
