Abstract
The utility model provides a rigid -flex circuit board of easily cutting apart behind paster, including fixed frame, with it is regional that fixed frame connects integrative soft board, the regional a plurality of soft board units that set up including the interval of soft board, every the soft board unit connection has at least one hardboard unit, the hardboard unit not with fixed frame is fixed. The utility model discloses a rigid -flex circuit board do not need with the hardboard unit is followed fixed frame is last to be cut down, so can not cause the evagination at hardboard unit edge or sunken does not influence yet the installation of hardboard unit on the camera has improved production efficiency simultaneously.
Description
Technical field
This utility model relates to circuit board manufacture field, the rigid-flexible combined circuit board easily split after particularly relating to a kind of paster.
Background technology
With the continuous lifting of photographic head pixel, adopt traditional plane formula cannot realize the function needs matched when photographic head designs.In order in limited assembling space, it is achieved the design requirement that performance is higher, stability is higher, it is necessary to adopt R-F plate to make.R-F plate is filmated flexible bottom and rigid bottom ingehious design to be connected, then is laminated in a single component, the printed wiring board of formation.R-F plate changes traditional planar design theory, expands the three dimensions concept of solid to, brings huge convenience to the design of electronic product.But, R-F plate is with hardboard district and flexible board area, and when external form molding, in industry, hardboard district adopts gong type to make, and flexible board area adopts stamp to make.As it is shown in figure 1, for the ease of SMT paster operation, generally can when gong type, hardboard district 1a designs at least one junction point 10a, plays the whole stability won in succession of guarantee.So, after paster, when flexible board area 3a is cut into multiple soft board unit 31a, it will usually adopt the mode of cut or stamping, junction point 10a is cut away or washed out.
When adopting stamping mode to make, owing to having interface between primary gong type and secondary stamp, the phenomenon of junction point position evagination or depression certainly will be had, so influence whether the assembling of client and change glue lid microscope base.
When adopting cut mode to make, although precision increases, but working (machining) efficiency is low, costly, and equipment purchase puts into very high.
Utility model content
The technical problems to be solved in the utility model is: provides a kind of and prevents the rigid-flexible combined circuit board that hardboard district is easily split after there is the paster of damage influence photographic head overall package when cutting.
For achieving the above object, the rigid-flexible combined circuit board of easily segmentation after described paster, including fixed frame, the soft board region being integrally connected with described fixed frame, described soft board region includes spaced multiple soft board unit, each described soft board unit is connected at least one hardboard unit, and described hardboard unit is not fixed with described fixed frame.
Wherein, on described hardboard unit, paster has multiple circuit chip.
Wherein, multiple described soft board unit it is separated into after the stamped cutting in described soft board region.
Described hardboard unit need not be cut down by rigid-flexible combined circuit board of the present utility model from described fixed frame, so evagination or the depression of described hardboard cell edges can't be caused, nor affects on the installation on photographic head of the described hardboard unit.

Detailed description of the invention
For further setting forth the technological means and effect thereof that this utility model takes, it is described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
Refer to Fig. 2, the rigid-flexible combined circuit board easily split after the utility model discloses a kind of paster.
After described paster, the rigid-flexible combined circuit board of easily segmentation includes: fixed frame 50, soft board region 30 and hardboard region 10；Described fixed frame 50 is generally PCB hardboard, and described soft board region 30 is FPC or rigid-flexible combined circuit board, and described hardboard region 10 is PCB hardboard.
Described soft board region 30 is integrally connected with described fixed frame 50, described soft board region 30 includes spaced multiple soft board unit 310, each described soft board unit 310 is connected at least one hardboard unit 110, and described hardboard unit 110 is not fixed with described fixed frame 50.
One described soft board unit 310 and a described hardboard unit 110 together constitute a circuit unit being arranged on photographic head.
In present embodiment, owing to described hardboard unit 110 is not fixed with described fixed frame 50, when carrying out next step cutting technique, need not move through and described hardboard unit 110 is cut down from described fixed frame 50, so evagination or the depression at described hardboard unit 110 edge can't be caused, nor affect on the installation on photographic head of the described hardboard unit 110.
On described hardboard unit 110, paster has multiple circuit chip.Hardboard unit 110 needs to carry out the paster of SMT before being cut, sticks the circuit chip of multiple process camera image data.
Wherein, multiple described soft board unit 310 it is separated into after the stamped cutting in described soft board region 30.
In the present embodiment, it is only necessary to cut in described whole soft board region 30, the circuit unit on the photographic head that multiple soft board unit 310 and hardboard unit 110 are integrated will be formed；Due to the assembled narrow space of photographic head, described hardboard region 10 is combined with photographic head, and by soft board unit 310 folding after, be attached by tie line and circuit board, reach space-saving purpose.
Refer to Fig. 3, in the present embodiment, described cut after paster before in order to prevent cutting after circuit unit be scattered, be inconvenient to take, generally can paste electrostatic adhesive tape 120 along the arragement direction of described hardboard unit 110, when after the multiple soft board unit 310 of the cut formation in described soft board region 30, it is possible to described circuit unit of manually taking from described electrostatic adhesive tape 120, more convenient.
This utility model is compared the rigid-flexible combined circuit board in background technology, has lacked hardboard unit 110 from the step cut down described fixed frame 50, it is possible to increase production efficiency reduces cost simultaneously.
The above; for the person of ordinary skill of the art; can conceive according to the technical solution of the utility model and technology and make other various corresponding changes and deformation, and all these change and deformation all should belong to this utility model scope of the claims.
