Abstract
The utility model discloses a kind of flexible camera wiring board, comprises substrate and is arranged on the some pads on substrate, and the distance of described pad pitch place wiring board edges of boards is 0.3mm; Each pad is all welded with nickel alumin(i)um alloy wire; described nickel alumin(i)um alloy wire is mainly made up of wire portion and enlarged portion; described wire portion one end is welded on described pad; the other end is integrated and is connected with described enlarged portion; described enlarged portion is a round; enlarged portion is for welding with chip connecting pin, and described wire portion periphery is provided with compound protective layer, and described wire and pad weld are coated with compound protective layer.The utility model is realized and being conducted by the nickel alumin(i)um alloy wire of good toughness; this kind of design can have sufficient arrangement space in the design of pad locations; be convenient to the overall construction design of camera, the distance of setting up in addition compound protective layer and increase pad and wiring board edges of boards has reduced the risk of pad weld breaking releasing.
Description
Technical field
The utility model relates to mobile phone camera technical field, is specifically related to a kind of flexible camera wiring board.
Background technology
In the prior art, on the normal pad that mobile phone camera chip correspondence is welded on to wiring board, conduct to realize.Use at present maximum welding gimmicks to be the connecting pin of camera chip to be directly fixed on pad by scolding tin.This processing technology makes pad and the position of chip connecting pin must be corresponding one by one, and in order to save the space of wiring board, existing technical staff is not able to a pad design near wiring board edges of boards position, and pad and the standing meter of wiring board edges of boards distance are less than 0.1mm.But when wiring board is for needs are installed, when its edges of boards must bend, this design increases the risk that connecting pin comes off from pad.Specifically, cause the cause coming off to be mainly, connecting pin and pad are for being rigidly connected, and tie point is again near edges of boards, therefore turn up once wiring board edges of boards, tie point place comes off with regard to easy fracture.
Utility model content
The purpose of this utility model is to overcome weak point of the prior art, and a kind of flexible camera wiring board is provided, and the switching performance between this wiring board and camera chip is excellent, does not turn up connecting pin is come off from pad because of its edges of boards.
The purpose of this utility model is achieved through the following technical solutions:
A kind of flexible camera wiring board, comprises substrate and is arranged on the some pads on substrate, the distance of described pad pitch place wiring board edges of boards is 0.3mm; Each pad is all welded with nickel alumin(i)um alloy wire; described nickel alumin(i)um alloy wire is mainly made up of wire portion and enlarged portion; described wire portion one end is welded on described pad; the other end is integrated and is connected with described enlarged portion; described enlarged portion is a round; enlarged portion is for welding with chip connecting pin, and described wire portion periphery is provided with compound protective layer, and described wire and pad weld are coated with compound protective layer.
The utility model has the following advantages and beneficial effect compared to existing technology:
(1) the utility model does not directly weld pad and chip connecting pin, conduct but realize the two by the nickel alumin(i)um alloy wire of good toughness, this kind of correspondence one by one that design needn't be worried connecting pin and pad on the one hand can have sufficient arrangement space in the design of pad locations; On the other hand, chip also has multiple considering on location layout, both can arrange on wiring board, also can move to other positions, is convenient to the overall construction design of camera.
(2) set up the design of nickel alumin(i)um alloy wire based on the utility model, the design space of pad locations is increased, inventor increases to 0.3mm by the distance of pad and wiring board edges of boards by 0.1mm, has reduced pad weld risk of breakage.
(3) the utility model is coated with compound protective layer in wire portion periphery, has further improved the toughness of wire, and has high insulation effect.
(4) the utility model not simply welds wire and pad, but has increased process for protecting, is provided with compound protective layer at wire and pad weld, has increased the firmness of weld.
Brief description of the drawings
Fig. 1 is the flexible camera circuit board structure of the utility model schematic diagram.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but the execution mode that the utility model is created is not limited to this.
Embodiment
As shown in Figure 1, a kind of flexible camera wiring board, comprise substrate 1, on one side 11 of substrate 1, be provided with three pads 21, on the another side 12 of substrate 1, be provided with three pads 22, pad 21 is 0.3mm apart from the distance on substrate one side 11, and pad 22 is also 0.3mm apart from the distance of substrate another side 12.On pad 21 and pad 22, be all welded with nickel alumin(i)um alloy wire, nickel alumin(i)um alloy wire is mainly made up of wire portion 3 and enlarged portion 4, enlarged portion 4 is exposed for welding with chip connecting pin, and wire portion 3 peripheries are provided with compound protective layer to improve toughness and the insulating properties of wire portion 3; One end of wire portion 3 is welded on corresponding pad 21 or pad 22, and wire portion 3 other ends are integrated and are connected with enlarged portion 4.In addition, in order to improve the firm welding of pad 21, pad 22 and wire portion 3, after wire portion 3 being welded on pad 21, pad 22, at the fixing colloid protective layer of the two weld.Concrete, enlarged portion 4 is circular, described colloid protective layer is PP glue.
The above embodiment has only expressed the execution mode of utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
Claims (1)
