Description
Technical field
The utility model relates to mobile phone manufacturing field, specifically a kind of mobile phone camera module minimizes PCB layout structure.
Background technique
For mobile phone in development process, function is more and more abundant, and the electronic component used on mobile phone is more and more.Existing
Under the premise of electronic component does not generate significant miniaturization, the space on Mobile phone PCB is relatively limited, is laid out increasingly crowded.
Chinese patent literature CN203086534U discloses " a kind of smart phone mainboard and smart phone " on July 24th, 2013, institute
Stating mainboard is composite structure, including the main PCB plate and secondary pcb board, the main PCB plate and the pair for the fixed component in two sides
Pcb board connection, is provided with the double-SIM card base of aerial mode in the main PCB back, lower in the double-SIM card base can
BB shielding case, the T deck of 1.5mm high and the battery holder of 1.5mm high are placed in overlapping.The applicant declares, using the utility model
The area of main PCB plate can be greatly reduced, its length dimension is especially substantially reduced, the length of battery can be made to increase
Add, capacity close and that battery is considerably increased under the premise of guaranteeing that intelligent machine complete machine thickness is not increased；And in main PCB board foot
It is very little it is smaller in the case where, be still able to achieve the function of double SIM card.It meets battery with ultra large capacity and is double SIM card intelligence hand
The market demand of machine.On mobile phone, either intelligent machine or function machine, camera module are all indispensable.Traditional takes the photograph
As the prevailing technology that module chip encapsulates is COB, larger-size sensitive component is arranged on the center of pcb board, size compared with
Other components such as small capacitor are around sensitive component distribution setting.Such conventional in layout, the PCB of entire camera module
Size is larger, occupies limited space in mobile phone, makes to be laid out new electronic component, realizes that new function becomes difficult, no
Conducive to the further development design of mobile phone.
Summary of the invention
Based on problem above, the utility model provides a kind of mobile phone camera module miniaturization PCB layout structure, takes the photograph mobile phone
As the PCB of mould group is significantly minimized, more spaces can be vacateed for interior of mobile phone, there is advantage in space layout.
In order to realize goal of the invention, the utility model adopts the following technical solution: a kind of mobile phone camera module miniaturization PCB
Layout structure, mobile phone camera module minimizes PCB layout structure, including PCB, sensitive component and normal electronics, photosensitive
Component is fixed on the front of PCB, and normal electronics are fixed on area of the back side of PCB relative to sensitive component position
In domain.
The mobile phone camera module of this programme design minimizes PCB layout structure, and sensitive component is still secured to PCB's
Front, to meet the status requirement of sensitive component, then on this basis by original around the other of sensitive component arrangement
Normal electronics have been transferred to the back side of PCB, i.e., with respect to sensitive component position.Due to the sensitive component of PCB
There is no normal electronics settings around position, therefore PCB size can narrow down to as far as possible and meet sensitive component arrangement i.e.
Can, to the area occupied of camera module is substantially reduced, to realize goal of the invention.
Preferably, it is additionally provided with the fender bracket of sheet, the planar dimension of fender bracket and the size fit at the back side PCB；Protection
In region of the back side for being fixed on PCB on one side of frame relative to sensitive component position；Fender bracket in a thickness direction in
Between be provided with protection hole, normal electronics are set in protection hole, and the thickness of fender bracket is not less than the height of normal electronics.
Fender bracket is the tablet of an intermediate aperture, can be metal material, is also possible to non-metallic material, shape is unlimited, size
It is advisable with being adapted to the size at the back side PCB.Fender bracket is fixed on the back side PCB, the back position of face sensitive component, protection hole
The back side PCB of position is exposed, and normal electronics are secured to this.It is required to meet protection, the thickness of fender bracket
Degree is no less than the height of normal electronics, and normal electronics can be helped to bear the stress from PCB thickness direction.
Preferably, the fender bracket is iron plate, it is welded and fixed with the back side PCB.Had using iron plate to make fender bracket
Four advantages, first is that intensity is high, second is that PCB and periphery cooling electronic component can be helped, third is that cost is advantageous, fourth is that can
To use automatic welding equipment high speed mass to handle.
Preferably, glue is perfused in protection hole, by normal electronics, the exposed portion in protection hole in the back side PCB
Divide together with being adhesively fixed with protection hole side wall.
In conclusion the beneficial effects of the utility model are: minimize the PCB of mobile phone camera module significantly, Ke Yiwei
Interior of mobile phone vacates more spaces, has advantage in space layout.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model.
Fig. 2 is traditional mobile phone camera module PCB layout structure.
Wherein: 1PCB, 2 sensitive components, 3 normal electronics, 4 fender brackets, 5 protection holes.
Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing.
As shown in Fig. 2, being traditional mobile phone camera module PCB layout structure.It can be seen that the size of PCB1 is larger,
It is fixed with sensitive component 2 at the positive middle part PCB, normal electronics 3 are centered around outside sensitive component and are laid out.
Embodiment as shown in Figure 1 minimizes PCB layout structure for a kind of mobile phone camera module.The cell-phone camera of this example
Mould group minimizes PCB layout structure, is still equipped with PCB1, sensitive component 2 and normal electronics 3, sensitive component is still
The front of PCB is set, but normal electronics are fixed on the back side of PCB.At the back side of PCB, the protection equipped with sheet
Frame 4.In this example, fender bracket is rectangular iron plate, and centre offers rectangular protection hole 5 in a thickness direction.Fender bracket is put down
The size fit of face size and the back side PCB, thickness are greater than the height of normal electronics.The one side of fender bracket is welded with the back side PCB
Fixation is connect, position is just at the back side of sensitive component position.In protection hole, a part at the back side PCB is exposed, it is general
Energization subcomponent is secured in protection hole.After fender bracket and normal electronics weld, also it is perfused into protection hole
Glue, normal electronics, the exposed part in protection hole in the back side PCB are adhesively fixed with protection hole side wall together with.
Since normal electronics have been transferred to the back side of PCB, and fender bracket and these normal electronics all positions
In the back side of sensitive component position, therefore PCB size can be contracted to meet sensitive component and be fixedly connected, from
And the area of plane of camera module is significantly reduced, accomplish miniaturization, more spaces can have been vacateed for interior of mobile phone, in sky
Between layout on have advantage.
