Abstract
The utility model discloses an assembling structure of a light-sensitive device on a PCB. The PCB comprises a mainboard and a small double sided board. Pads for installation are respectively and correspondingly arranged on a bottom face of the small double sided board and the mainboard. The network connection of the light-sensitive device, the small double sided board and the mainboard is of one-to-one correspondence. The light-sensitive device is attached to a top face of the small double sided board. The assembling structure of the light-sensitive device on the PCB can well solve the assembling problem of the light-sensitive small board, reduces material and labor cost, saves the structure space, and improves production efficiency.
Description
Technical field
The utility model relates to hardware electronic, particularly relates to a kind of light sensation device at the PCB(printed circuit board (PCB)) on assembly structure.
Background technology
As shown in Figure 1, traditional light sensation platelet assembling mode in the mobile phone is on PCB 10, by the FPC(flexible PCB) 20 add B TO B(plate to plate) mode of connector 22 connects, light sensation device 14 is attached on the FPC 20, and light sensation device 14 height problem normally the structural engineer by below FPC 20, adding foam or other structural member 18 bed hedgehoppings solve.The light sensation device is installed like this need to increase a FPC, a pair of B TO B connector, and foam or structural member also need manual assembly, and cost increases a lot, and the assembling trouble has also taken the space on structure and the PCB, and assembly reliability neither be fine.Under this background, need a kind of new assembly structure to solve this problem.
The utility model content
Main purpose of the present utility model just provides the assembly structure of a kind of light sensation device on PCB, overcomes the above-mentioned deficiency of prior art.
For achieving the above object, the utility model is by the following technical solutions:
The assembly structure of a kind of light sensation device on PCB, described PCB comprises mainboard and the little double sided board that is installed on the mainboard, be provided with accordingly separately on the bottom surface of described little double sided board and the described mainboard for the pad of installing, and the network connection of described light sensation device, little double sided board and described mainboard is corresponding one by one, and described light sensation device is mounted on the end face of described little double sided board.
Preferably, the thickness of described little double sided board and predefined light sensation device packaging height adapt.
Preferably, the thickness of described little double sided board is 1.0mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm or 2.0mm.
The technique effect that the utility model is useful is:
Assembly structure of the present utility model only increases a little double sided board on the basis of PCB mainboard, compared with prior art, can reduce a FPC, a pair of B TO B connector, and a foam, and can reduce the manual assembly cost.The utility model has been saved the space on structure and the PCB, has reduced material and cost of labor, and structural reliability well improved, but also reduces the trouble degree of light sensation device assembling, has improved production efficiency.
Description of drawings
Fig. 1 and Fig. 2 are the assembly structure schematic diagram of prior art light sensation device on PCB;
Fig. 3 and Fig. 4 are the assembly structure schematic diagram of an embodiment of the utility model.
Embodiment
By reference to the accompanying drawings the utility model is further described in detail by the following examples.
See also Fig. 3 and Fig. 4, in an embodiment, according to the assembly structure of a kind of light sensation device on PCB, described PCB comprises mainboard 10 and the little double sided board 12 that is installed on the mainboard 10, be provided with accordingly separately on the bottom surface of described little double sided board 12 and the described mainboard 10 for the pad 16 of installing, and the network connection of described light sensation device 14, little double sided board 12 and described mainboard 10 is corresponding (not shown) one by one, and described light sensation device 14 is mounted on the end face of described little double sided board 12.
It is fixed that the thickness of described little double sided board 12 can come according to structural requirement, for example is arranged to adapt with predefined light sensation device packaging height.
During assembling, first the light sensation device is attached on the little double sided board (or claiming platelet or little pcb board), again platelet is attached on the mainboard, paste the hardboard mode by platelet and mainboard hardboard and realize assembling.
Particularly, can first according to light sensation device package size, design a little double sided board.The platelet bottom surface is provided with and light sensation device bonding pad pad of a size, and network connection is corresponding one by one.Also leave the pad of corresponding size on the mainboard, network is also corresponding one by one.The thickness of little pcb board can be by actual requirement, such as make the different-thickness such as 1.0mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm or 2.0mm according to the requirement for height of structure.Platelet is made the jigsaw mode, is combined into the light sensation device to be attached to one by one on platelet after the larger large jigsaw again, and this mode can greatly improve the light sensation device is labelled to efficient on the platelet.After posting, large jigsaw is divided into a piece platelet, again platelet in the mode of braid or do the mode such as tool and be attached on the mainboard again.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
Claims (3)
