As shown in Figs 1-4, the embodiment of the present invention provides a kind of camera module structure, including lens assembly 10 and fixed setting Photosensory assembly 20 below lens assembly 10, wherein photosensory assembly 20 includes stiffening plate 21 and is fixed on stiffening plate 21 The centre of the wiring board 22 on surface, wiring board 22 is equipped with hollowed out area.The reliable of wiring board 22 can be improved in the setting of stiffening plate 21 Property, and then improve the reliability of camera module.
Sensitive chip 23, institute are also fixed in the hollowed out area of the wiring board 22, the upper surface of the stiffening plate 21 Sensitive chip 23 is stated to be electrically connected by conductor wire with wiring board 22.The setting of hollowed out area makes that camera shooting can be accommodated among wiring board 22 The following sensitive chips of mould group, are effectively reduced the height of camera module.
Wiring board 22 described in the present embodiment has a First terrace 221 of inside and the second step face 222 in outside, and described the Bracket 25 is fixed on one step surface 221, the bracket 25 makes IR piece 24 be formed in sensitive chip 23 to fixed IR piece 24 Surface, the assembling mode is more controllable, and IR piece 24 be not easily susceptible to mould group external force influence cause to rupture, mould group whole height Or outer dimension does not also become larger.Specifically, the lower end surface of the bracket 25 is fixed on First terrace 221, bracket 25 Lower end surface upwardly extend and bent inwards again in same level direction, the IR piece 24 passes through viscous with bracket 25 with wiring board 22 Jelly fitting is fixed in bracket 25.Preferably, there are four the brackets 25, in being symmetrically disposed on First terrace 221, So that fixation uniform force of the bracket 25 to IR piece.
By by the intermediate hollow out of wiring board 22, the lower surface of wiring board 22 is sticked stiffening plate 21, and photosensitive core the present embodiment The hollowed out area of the upper surface of stiffening plate 21, wiring board 22 is arranged in piece 23, and IR piece 24 is formed in the top of sensitive chip 23, makes The height of camera module maximum can reduce 0.69mm on the basis of existing, adapt to the development of screen end product comprehensively.In addition, line For road plate 22 due to internal layer circuit design requirement, the surface of wiring board 22 has the surface of lines, protrusion etc. namely wiring board 22 flat Whole degree is poor, and the present embodiment is by the way that by the intermediate hollow out of wiring board 22, sensitive chip 23 is placed on the stiffening plate 21 of surfacing, makes Obtaining sensitive chip 23 also has preferable flatness, and camera module has preferable image quality.
Escape gas as a further improvement, being also formed between the sensitive chip 23 and the periphery and wiring board 22 of IR piece 24 Hole 26, so that sensitive chip 23 and the interval of wiring board 22 are arranged, sensitive chip 23 is connect with wiring board 22 by conductor wire 27.It leads Electric wire 27 can be gold thread, and the camber of conductor wire 27 can be controlled in 0.1mm hereinafter, the extreme higher position of conductor wire 27 is not higher than route The upper surface of plate 22.
As a further improvement, the camera module further includes electronic component 28, the fixed assist side 22 of electronic component 28 First terrace 221 on, make 28 plastic packaging of electronic component in the non-photo-sensing area (MOC technique) of sensitive chip 23, can effectively reduce Mould group overall dimensions.Wherein electronic component 28 can be the elements such as capacitor, resistance.The electronic component 28 is avoided setting with bracket 25 It sets.It should be understood that sensitive chip 23 has intermediate photosensitive area and peripheral non-photo-sensing area is the prior art, photosensitive area be used for into Row photosensitization, non-photo-sensing area can be used for connecting conductor wire 27 etc..
In the present embodiment, the stiffening plate 21 is square, and the hollowed out area of the wiring board 22 is also square, and vacancy section The adjacent two edges line in domain is parallel with the adjacent two edges line of stiffening plate 21 respectively.In this way, can be easily installed rectangular photosensitive Chip 23, so that the utilization rate of hollowed out area maximizes, and rationally designs the structure of wiring board 22, wiring board 22 is not The region of hollow out can carry lens assembly 10, electronic component 28 and have the site being electrically connected with elements such as sensitive chips 23.
The lens assembly 10 that is fixed as of lens assembly 10 described in the present embodiment and photosensory assembly 20 fixes assist side 22 Second step face 222 on, specifically can be lens assembly 10 frame-type lower end surface and second step face 222 by AA glue 29 patch It closes and fixes.
Stiffening plate 21 described in the present embodiment with a thickness of 0.1mm, stiffening plate 21 is reinforcement steel disc.The wiring board 22 is Flexible circuit board 22, with a thickness of 0.25mm.The IR piece with a thickness of 0.11mm.Specifically, camera module height h is 4.46mm。
For lens assembly 10 including eyeglass etc., lens assembly 10 should be located at the photosensitive of the sensitive chip 23 in the present embodiment Path, so that the light being reflected by the object can be by the mirror when the camera module is used to acquire the image of object Further it is suitable for carrying out photoelectric conversion by the sensitive chip 23 receiving after the processing of head assembly 10.The lens assembly 10 Periphery be also provided with motor sub-assembly, the automatic focusing function of lens assembly 10 may be implemented.It should be understood that of the invention Camera module can be used for cameras with fixed focus mould group and autozoom camera module, with no restriction.
Camera module use scope in the present embodiment includes but is not limited to mobile phone.
When the camera module assembling of the present embodiment, stiffening plate 21 is first bonded fixation with wiring board 22, wiring board 22 can lead to Overetch forms hollowed out area and First terrace 221;Fixed sensitive chip 23 is bonded on the stiffening plate 21 of hollowed out area again, Sensitive chip 23 is connect by conductor wire 27 with wiring board 22;Glue is fixed in the non-photo-sensing region coating of sensitive chip 23 again, The fitting of IR piece 24 is fixed on the First terrace 221 of wiring board 22 on sensitive chip 23 and fixes bracket 25 and IR piece and electricity Subcomponent;Finally on the second step face 222 by lens assembly 10 by the fixed assist side 22 of AA glue, camera module is completed Semi-finished product assembling.
Finally, it should be noted that above embodiments be only to illustrate the technical solution of the embodiment of the present invention rather than to its into Row limitation, although the embodiment of the present invention is described in detail referring to preferred embodiment, those skilled in the art It should be understood that the technical solution of the embodiment of the present invention can be still modified or replaced equivalently, and these are modified or wait The range of modified technical solution disengaging technical solution of the embodiment of the present invention cannot also be made with replacement.
