The utility model content
Based on this, be necessary to propose the camera module that a kind of bent area is difficult for tearing.
A kind of camera module, comprise flexible PCB and be arranged on the microscope base assembly on described flexible PCB front, described flexible PCB has the bending part that exceeds described microscope base assembly, the corresponding described microscope base assembly in the back side of described flexible PCB is provided with stiffening plate, and the edge of described stiffening plate extends and exceeds described microscope base module to described bending part.
In embodiment, described stiffening plate is steel plate therein.
In embodiment, the length that the edge of described stiffening plate exceeds described microscope base module is 0.2～0.5mm therein.
In embodiment, the length that the edge of described stiffening plate exceeds described microscope base module is 0.3mm therein.
In embodiment, the dual-side in the zone that described bending part and described microscope base assembly are adjacent is equipped with circular arc chamfering therein.
In embodiment, the both sides that described stiffening plate exceeds described microscope base components are provided with the arc gap corresponding with described circular arc chamfering therein.
Therein in embodiment, the front of described flexible PCB scribbles reinforcement glue in described bending part and the adjacent zone of described microscope base assembly.
In embodiment, described reinforcement glue is ultraviolet curing glue therein.
In embodiment, the coating thickness of described reinforcement glue is 0.3～0.5mm therein, and width is 0.5～0.8mm.
Therein in embodiment, the rectangular triangle in the cross section of described reinforcement glue on the flexible circuit plate thickness direction.
Above-mentioned camera module, the edge of the stiffening plate at the flexible PCB back side extends and exceeds the microscope base module to bending part, makes the bent area strength increase, prevents that bent area from tearing and wire fracture easily.

Fig. 1 is the front view of the camera module of an embodiment;
Fig. 2 is assembled with the schematic diagram of the flexible PCB of sensitive chip in the camera module;
Fig. 3 is the side view of camera module.
Embodiment
Please refer to Fig. 1 to Fig. 3, a kind of camera module 100, comprise flexible PCB 110 and be arranged on the microscope base assembly 120 on flexible PCB 110 fronts.Microscope base assembly 120 is arranged on an end in the front of flexible PCB 110, and namely an end of flexible PCB 110 is mutually stacked with microscope base assembly 120.The corresponding microscope base assembly 120 in the back side of flexible PCB 110 is provided with stiffening plate 130.Stiffening plate 130 is selected steel disc.Herein, the concept at front and the back side is comparatively speaking, should be with this literal not being limited to the explanation of present techniques scheme.The part (i.e. mutually not stacked with microscope base assembly 120 part) that the other end of flexible PCB 110 exceeds microscope base assembly 120 is bending part 112, the needs of bending while using to meet.
Fig. 2 is the schematic diagram that is assembled with the flexible PCB 110 of sensitive chip 140, and microscope base assembly 120 now not yet is installed.In Fig. 2; flexible PCB 110 is provided with the golden finger 114 that 140 dozens of gold threads of sensitive chip are used in sensitive chip 140 belows; golden finger 114 has the cabling (not shown) downwards, and the regional A of golden finger 114 belows is namely the zone that is provided with the coverlay that protection circuit uses.
Because the cabling of coverlay and its below has difference in height in short transverse (being on flexible PCB 110 thickness directions), and the adjacent zone itself of bending part 112 and microscope base assembly 120 is exactly the zone of easily tearing when bending, in order to prevent aforementioned adjacent zone, tear and walk thread breakage, please refer to Fig. 3, in the present embodiment, the edge of the stiffening plate 130 at flexible PCB 110 back sides extends and exceeds described microscope base assembly 120 to described bending part 112, the length L exceeded is 0.2～0.5mm, be preferably 0.3mm, like this, the intensity in the zone that bending part 112 and microscope base assembly 120 are adjacent also is increased, this adjacent zone just can not torn easily like this, distance between the edge of the edge of stiffening plate 130 and golden finger 114 is increased, wire can not rupture easily.
In the present embodiment, the adjacent zone of the front of flexible PCB 110 and microscope base assembly 120 also scribbles reinforcement glue 150, further to increase the intensity in this adjacent zone, while preventing 100 use of camera module, the adjacent zone of bending part 112 and microscope base assembly 120 tears easily and prevents that the wire of this location from opening circuit easily.Reinforcement glue 150 adopts the UV(ultraviolet curing) glue, the thickness of coating is generally 0.3～0.5mm, and width is generally 0.5～0.8mm.As shown in Figure 3, the general rectangular triangle in the cross section of reinforcement glue 150 on flexible PCB 110 thickness directions.
In addition, described bending part 112 is equipped with circular arc chamfering 116 at the dual-side with the adjacent zone of microscope base assembly 120, make between bending part 112 and rigid region with arc transition, set-up mode than the right angle transition, arc transition can prevent that bending part 112 from tearing easily, particularly in the situation that microscope base assembly 120 forms a step after installing.
As shown in Figure 2, described stiffening plate 130 both sides that exceed described microscope base assembly 120 parts are provided with the arc gap 132 corresponding with described circular arc chamfering 116.
In the present embodiment, the back side of flexible PCB 110 is provided with connector 160 on bending part 112, can form new module with other elements, thereby enlarges the range of application of camera module 100.
The above embodiment has only expressed several embodiment of the present 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 domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
