Description

Camera module and its molding photosensory assembly and mould

Technical field

The utility model is related to camera module field, further, is related to camera module and its one-tenth of moulding technology making Pattern tool and manufacture method.

Background technology

Camera module be intelligent electronic device can not obtain one of scarce part, citing ground but be not limited to smart mobile phone, phase Mechanical, electrical brain equipment, wearable device etc..And the continuous development with various smart machines and popularization, the requirement to camera module Also more and more higher.

In recent years, the development that intelligent electronic device generation is advanced by leaps and bounds, increasingly tends to lightening, and camera module will adapt to Its development, also increasingly requires multifunction, lightening, miniaturization, so that the more and more thinner that electronic equipment can do, and full Sufficient equipment is for the imaging requirements of camera module.Therefore camera module production firm is persistently devoted to design, manufactures satisfaction The camera module of these requirements.

Molded packages technology is the emerging a kind of encapsulation technology growing up on the basis of traditional COB encapsulation.As shone Figure 1A Shown, it is the wiring board using the encapsulation of existing integral packaging technology.In such an embodiment, encapsulation part 1 is passed through integral packaging Mode is packaged in wiring board 2 and sensitive chip 3, and coats the electronic devices and components on wiring board and electrical connection chip and circuit The lead of plate, thus the space that the electronic devices and components reducing camera module independently take is so that the size of camera module can subtract Little, and solve the problems, such as the image quality of the dust impact camera module of attachment on electronic devices and components.

With respect to traditional support rack type COB encapsulation technology, this encapsulation technology in theory, has more excellent Gesture, but for a period of time, this encapsulation technology only stays in theory or manual experimental stage, and does not obtain very well Enforcement, do not put into reality production in carry out quantify produce, trace it to its cause, have following aspects.

First, though integral packaging technology is one in other large scale industry fields knows technology, but in camera module Field is but new application, and different industries need the object that produces by way of molding different, faced by problem also different.With As a example smart mobile phone, body is more and more lightening, so thickness is fewer and feweri, therefore it is required that camera module also to reach such Thickness, just will not increase the integral thickness of mobile phone, well imagine, the part in camera module is all in less size etc. Level is processed, and the ideal structure of therefore design but can not be produced by way of conventional.In said structure, it usually needs Through hole is formed by described encapsulation part 1, provides passage of light for the sensitive chip 3 on wiring board 2, this through hole is commonly designed For vertical flat column, this structure does not have king-sized defect for basic theories in structure, but does not consider real The problem that border volume production exists when producing.That is, this technology only rests on the manual test stage, actual life but can not be put into Produce.More specifically, packaging technology is required for mould, with reference to Figure 1B and Fig. 1 C, when the forming blocks 4 of the upper mould of mould are During vertical flat column, in moulding process, in upper mould with the position that contacts of the encapsulation part that formed, in mould separating mold member During material, because upper mould bottom is sharp prismatic so that mould can affect to mold the shape of the encapsulation part 1 being formed in the process extracted Shape, so as to produce deformation, such as produces overlap, in addition when upper mould is pulled out and departs from encapsulation part, the outside of upper die forming block 4 Face can produce therebetween larger frictional force with encapsulation part 1 always, thus being likely to damage encapsulation part 1, this impact exists Large scale industry field may be able to be ignored, but in this undersized fine-grained production field of camera module, but becomes one Individual vital influence factor, so the through hole theoretical construct of vertical flat column is feasible, unsuitable volume production is implemented.

Secondly, camera module is a kind of optical electron device, and light is the key factor determining image quality.Reference picture 1D, in conventional stent assembling mode, the support 5 being installed on wiring board needs the installing space 6 of reserved electronic devices and components, because This formed in concave space, the presence in this space improves the size of camera module, but after light incidence, little direct irradiation in The reflection light of rack inner wall, therefore rack inner wall is less, does not interfere with the image quality of camera module.And work as support and be replaced For existing flat column encapsulation part 1 when, reference picture 1E, compared to supporting structure, after the light incidence camera lens of identical incidence angle, The light of reflection will not be produced in supporting structure, and the inwall of encapsulation part 1 can be acted in the structure of integral packaging, and Reflection light is accessible to sensitive chip 3, thus increasing stray light so that the image quality of camera module reduces, because For this is from quality of optical imaging, the structure of through hole of encapsulation part 1 interior formation side shape post simultaneously is not suitable for putting into application.

Finally, when being assembled into camera module, encapsulation part 1 typically requires the installation part such as camera lens or motor, therefore seals Dress portion 1 needs to meet certain structural strength, and when therefore arranging encapsulation part 1 shape, needing will be anti-to luminous flux, structural strength, light Penetrate rate, conveniently stripped and prevent the demoulding from numerous aspects such as the damage of encapsulation part 1 are taken into consideration to design, and existing encapsulation part These factors are not obviously taken into consideration by 1 structure.
