The utility model discloses a flexible circuit board can be used for installing the coil, for the focusing of image sensor, anti -shake motion provide elasticity, can simplify the structure composing of the module of making a video recording simultaneously to reduce its volume greatly.
Description
Technical field
The utility model relates to the accessory for camera module, particularly relates to FPC soft board wherein.
Background technology
Along with continuous renewal and the improvement of mobile terminal product, its effect of taking pictures can match in excellence or beauty card camera substantially, and therefore compared with camera, people more gladly use panel computer or smart mobile phone to go to realize camera function.
And manufacturer is in order to strengthen the camera function of the products such as mobile phone, generally all various improvement being carried out to voice coil motor, adding the function such as auto-focusing and even optical anti-vibration, to realize best effect of taking pictures.But current all kinds of motor all exists respective shortcoming, as in the process of voice coil motor, the imageing sensor in camera module is difficult to accomplish dust-proof, easily causes scrapping.In addition, motor needs the camera lens matched to form camera module, and therefore the design of motor limits the design of camera lens.The motor that volume is little cannot mate large camera lens.Further, for optical anti-vibration motor, can only realize both direction stabilization compensate, and actual take pictures in shake be three directions.Three direction optical anti-vibration can only be realized by moving image transmitting sensor.
Except using voice coil loudspeaker voice coil focusing motor, realize auto-focusing and optical anti-vibration can also be adopted alternatively, namely keep camera lens motionless and moving image transmitting sensor.Not only can realize auto-focusing by moving image transmitting sensor, the optical anti-vibration correction on 3 directions can also be realized, realize the optimum efficiency of taking pictures.But traditional moving image transmitting sensor technology can cause modular volume excessive, therefore fails to be applied in the middle of cell-phone camera module.Cell-phone camera module is still taken as the leading factor with the voice coil motor of moving lens at present.
Summary of the invention
The utility model is in order to the excessive problem of the technology volume that solves moving image transmitting sensor in above-mentioned prior art, a kind of flexible PCB for welding image transducer is proposed, this flexible PCB can make imageing sensor free movement, can not increase again the volume of camera module simultaneously.
The flexible PCB that the utility model is used for welding image transducer comprises the first area and second area that set gradually, described second area comprises and is positioned at its center and the central part welded with imageing sensor and the frame portion being positioned at central part surrounding, described frame portion is provided with equally distributed coil groups, and described central part and frame portion are connected by elastic arm with the edge of second area.
The coil of described coil groups is PCB coil.Preferably, the coil of described coil groups is the PCB coil utilizing the partially flexible circuit board of second area to be formed.The building block of further simplification camera module.
The pin of imageing sensor and the lead-in wire of coil are electrically connected with first area by described elastic arm.Described elastic arm can utilize partially flexible circuit board to make by cutting flexible PCB.Described elastic arm can also be removed its high polymer underlay substrate by described partially flexible circuit board and be made up of its layers of copper.Or described elastic arm adopts conducting metal to make.
The utility model, in order to solve the miniaturization issues of the camera module of moving image transmitting sensor, proposes a kind of flexible PCB being integrated with mechanical spring silk and electricity coil and electronic circuit utilizing MEMS technology to process.Image sensor chip combines with this circuit board by COB or CSP processing procedure, center image Sensor section hangs up by the mechanical spring silk part on circuit board, it is made to possess X, three directions of Y, Z translation and have the freedom of motion of six direction around three directions that central point rotates altogether.The core that circuit board is connected with imageing sensor is also integrated with electricity coil, when it is energized, can produce the active force of moving image transmitting sensor under outside magnetic field effect, realizes imageing sensor in a plurality of directions mobile and controls.
Accompanying drawing explanation
Fig. 1 is the explosive view of utility model;
Fig. 2 is of the present utility model overlooking.
Embodiment
Below in conjunction with drawings and Examples, structural principle of the present utility model is described.
Fig. 1, Fig. 2 give the flexible PCB for welding image transducer of the present utility model, it is divided into two regions, one is the first area 1 being positioned at below in Fig. 1, another is the second area 2 being positioned at top, first area 1 for the coil 3 in conducting second area 2 and with motherboard platform communication, second area 2 is used for welding image transducer, is electrically connected by coil 3 with first area 1.
Wherein, second area 2 has the central part 21 being positioned at its center, has leg 22 above this central part, is used for welding with imageing sensor, and the surrounding of central part 21 is named and cries frame portion 23, and portion is uniform-distribution with coil groups with frame.Coil groups at least comprises more than 2 coils 3, the example provided in figure is for being provided with four coils 3, frame portion 23 and central part 21 are all square, and four coils 3 are evenly distributed on four edges, and then central part 21 and frame portion are connected by elastic arm with the edge of second area.In other examples, circle can also be processed in central part and frame portion, is then uniformly distributed three coils 3, and the spacing center of circle of each coil 3 is 120 degree of angles.
In the present embodiment, coil 3 is the PCB coil adopting MEMS micro fabrication (Micro-Electro-MechanicalSystem MEMS (micro electro mechanical system)) to make, because PCB itself is the sandwich construction be made up of Copper Foil and insulating barrier, every layer of Copper Foil can etch multiple circle, the circle of levels, by via hole conducting, finally just defines the PCB coil be integrated with PCB.
In addition, can also based on the present embodiment, expand further, because second area 2 itself is also PCB(flexible PCB), so can coil 3 be made on the flexible PCB of second area 2, utilize the PCB coil that the partially flexible circuit board of second area 2 is formed, simplify the structure of camera module further, reduce its volume simultaneously.
Be arranged on the elastic arm 24 of imageing sensor and coil surrounding, imageing sensor not only can be provided in the elasticity of planar carrying out translation, rotation perpendicular to optical axis and pump along optical axis direction, be used for controller chassis portion coil and be arranged on the position of the imageing sensor in frame portion, realize the function such as focusing or stabilization of camera module.Meanwhile, the pin of imageing sensor and the lead-in wire of coil are also electrically connected with first area, for the conducting with mobile communication and coil by elastic arm 24.Elastic arm 24 can be supported by the flexible PCB in cutting second area 2, utilizes the partially flexible circuit board in second area 2 to form elastic arm.The partially flexible circuit board forming elastic arm can also be processed further, remove its high polymer underlay substrate, only leave its layers of copper and form new elastic arm, avoiding high polymer affects the spring function of elastic arm, and it is flexible, ductility is better than flexible PCB.Certainly can also conducting metal be adopted completely to make elastic arm, make it pin of the lead-in wire of coil and imageing sensor can be drawn.
Should be understood that, the above-mentioned description for specific embodiment is comparatively detailed, and therefore can not think the restriction to the utility model scope of patent protection, scope of patent protection of the present utility model should be as the criterion with claims.
