Description
Technical field
The utility model relates to mobile phone camera module, specifically refers to a kind of mobile phone camera module.
Background technology
The camera module of usual mobile phone is all generally by camera lens, motor, support, the formations such as flexible PCB, its production process is pasted on flexible PCB by stiffening plate, then by welding electronic elements on flexible PCB, cover element with support and support and wiring board sealed fixing with black glue, then paste on support by motor, finally fixed to correct position glue by camera lens precession motor, such mobile phone high-pixel camera head has just been assembled.
In order to realize being connected with cell phone mainboard, existing camera module also has downward extension in flexible circuit board, the serial communication connector adopting MIPI serial line interface is provided with at the back side of this extension, as shown in Figure 1, the imageing sensor 5 that this mobile phone camera comprises camera lens 1, motor 2, support 3, flexible circuit board 4 and is arranged in flexible circuit board 4, described imageing sensor 5 has OV8825 type sensor chip 51; The back side of described flexible circuit board 4 is also provided with reinforcement steel disc 41, and reinforcement steel disc 41 ground connection; Described flexible circuit board 4 also has downward extension 42, is provided with the serial communication connector 6 adopting MIPI serial line interface at the back side of this extension 42, has FR4 reinforcing chip 43 and soft foam one-faced tapes 44 successively in the front of this extension.But general conventional FP4 glass-fiber-plate makes reinforcement stiffened FPC flexible board, to weld more reliably when SMT surface mount crosses tin stove bottom the connector of said structure.This reinforcement mode because connector often there will be the problem of tilting when SMT surface mount crosses tin stove, causes the pin of position, connector corner to tilt very easily rosin joint, dry joint, causes product function bad.And because FR4 glass fiber plate heat-conducting effect is general, the reliability that whole connector pin is connected with flexible circuit board is also unstable.
Utility model content
The purpose of this utility model overcomes above-mentioned deficiency of the prior art, provides a kind of camera module connector pin welding reliable, avoid the mobile phone camera module of pin rosin joint, dry joint.
The purpose of this utility model is achieved through the following technical solutions:
A kind of mobile phone camera module, comprise camera lens, the motor be connected with camera lens, motor is arranged on a support, the imageing sensor being provided with flexible PCB below support and being arranged in flexible circuit board; Described flexible circuit board also has downward extension, serial communication connector is provided with at the back side of this extension, it is characterized in that: the back side of described extension is provided with the welding foot position for the pin welding with serial communication connector, serial communication connector is rectangle, and the appearance profile of the welding foot position at the pin place of its four corner areas large 0.05mm more than more monolateral than the appearance profile of the welding foot position at the pin place of zone line.
Improve as one of the present utility model, the front of described extension is successively with steel disc and soft foam one-faced tapes.
As another improvement of the present utility model, the two ends of described serial communication connector are arranged with four convex pin, and the bottom of described convex pin is concordant with welding foot position.
Preferably, the surface of described extension is provided with an electromagnetism rete.Discharged in time by the electrostatic of electromagnetism rete by itself, anti-electromagnetic interference capability is strong.
The utility model has the following advantages and beneficial effect compared to existing technology:
1, the utility model is by expanding the appearance profile of the welding foot position at the pin place of four corner areas in welding foot position, even if occur still ensureing that it fully contacts with the pin of serial communication connector, avoids pin rosin joint, dry joint when tilting at connector.
2, use steel disc instead to do reinforcement, replace existing FP4 glass-fiber-plate, after steel disc is heated, heat conduction is relatively more even, heat-conducting block, makes connector weld upper tin even, the reliability that whole connector pin is connected with flexible circuit board.
3, because the two ends of serial communication connector are arranged with four convex pin, when serial communication connector welds with flexible circuit board, due to the conflict effect between convex pin and the steel disc in flexible circuit board front, the problem occurring that connector tilts can be avoided.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of existing camera module.
Fig. 2 is the right apparent direction structural representation of the utility model hand camera module.
Fig. 3 is the backsight direction structure schematic diagram of the utility model hand camera module.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
Embodiment
As shown in Figure 2 and Figure 3, the present embodiment provides a kind of mobile phone camera module, comprises camera lens 1, the motor 2 be connected with camera lens 1, and motor 2 is arranged on a support 3, is provided with flexible PCB 4 and is arranged on the imageing sensor 5 in flexible circuit board 4 below support 3; The back side of described flexible circuit board 4 is also provided with reinforcement steel disc 41, and the surface of reinforcement steel disc 41 is with double faced adhesive tape 45, described flexible circuit board 4 also has downward extension 42, serial communication connector 6 is provided with at the back side of this extension 42, the back side of described extension 42 is provided with the welding foot position 62 for welding with the pin 61 of serial communication connector 6, serial communication connector 6 is rectangle, and the appearance profile of the welding foot position at pin 61 place of its four corner areas large 0.05mm more than more monolateral than the appearance profile of the welding foot position at pin 61 place of zone line.
The front of described extension 42 is successively with steel disc 421 and soft foam one-faced tapes 44.Use steel disc instead to do reinforcement, replace existing FP4 glass-fiber-plate, after steel disc is heated, heat conduction is relatively more even, heat-conducting block, makes connector weld upper tin even, the reliability that whole connector pin is connected with flexible circuit board; Meanwhile, soft foam one-faced tapes 44 can play shockproof cushioning effect, is also beneficial to the stable of connector.
The two ends of described serial communication connector 6 are arranged with four convex pin 63, and the bottom of described convex pin 63 is concordant with welding foot position 62.Two ends due to serial communication connector are arranged with four convex pin, when serial communication connector welds with flexible circuit board, due to the conflict effect between convex pin and the steel disc in flexible circuit board front, can avoid the problem occurring that connector tilts.
Preferably, the surface of described extension 42 is provided with an electromagnetism rete 422.Discharged in time by the electrostatic of electromagnetism rete by itself, anti-electromagnetic interference capability is strong.
