Description
Technical field
The utility model is related to a kind of circuit board technology field, and in particular to a kind of anti-rigid-flexible combined circuit plate of folding.
Background technology
Rigid-flex combined board is not common circuit board, and it has had rigid layer and flexible layers concurrently, is a kind of multilayer printed circuit
Plate.Typically (four layers) rigid-flex combined board printed circuit board (PCB) has a polyimides core, and its upper and lower surface has copper covered
Paper tinsel.External rigidity layer is made up of the FR4 of one side, and they are laminated into the two sides of flexible core, are assembled into the PCB of multilayer.Rigid-flexible knot
Plywood is widely used, but being used in mixed way and multiple making step, the process time of rigid-flex combined board due to multiple material
Longer, cost of manufacture is higher.When making multilayered rigidity and flexibility board, the processing technology of flexible layers is again completely different with outside FR4 layers.
Because the every aspect that different materials make must be sniped together by lamination, then drill again, electroplate.Therefore, one is made
The time of individual typical four layers of rigid-flexible combination printed circuit board (PCB), may be more long than making the four of standard layers of printed circuit board
5 to 7 times.Even so, rigid-flex combined board for project is provided preferable solution, what is utilized is the mutually interconnection of flexible substrate
Connect, rather than the connection equipment of multiple PCB, here it is the key for taking up room and reducing weight is reduced, this exactly many design
Required.
The flexible layers of rigid-flex combined board rigid region and flexible region joint in use because being extruded by two rigid plates,
Larger stress is born, easily stress splits when occurring significantly to bend at this, causes circuit board communications bad.
Utility model content
The utility model is in order to solve the above problems, there is provided one kind is readily produced, and is prevented from rigid region and flexible region
The rigid-flexible combined circuit plate of anti-folding of joint fracture.
The utility model is adopted the following technical scheme that：
A kind of anti-rigid-flexible combined circuit plate of folding, including circuit board body, the circuit board body include flexible circuit block and
It is positioned close to the rigid region on the top and bottom at flexible circuit block two ends, opposite end and the flexible circuit block of the both sides rigid region
Junction be provided with flexible fastening piece, the junction of the flexible fastening piece and rigid region and with the junction of flexible circuit block all
It is arc transition.
Used as a kind of optimal technical scheme of the present utility model, the opposite end of the both sides rigid region is provided with convex portion, convex portion
Groove is formed between flexible fastening piece.
Used as a kind of optimal technical scheme of the present utility model, the flexible fastening piece is made up of elastic insulator material.
The beneficial effects of the utility model are：
The utility model simple structure, it is easy to produce, flexible fastening is provided with the junction of rigid region and flexible circuit block
Part, and junction is all arc transition, and the flexible layers for working as flexible circuit block and the junction of rigid region can be caused by squeezing
Stress concentration will not be produced when pressing or pullling, strengthens its ability to bear, effectively prevent because caused by the fracture of junction
Circuit board communications are bad；And convex portion is provided with the opposite end of both sides rigid region, form groove then between convex portion and flexible fastening piece
It is the further protection to rigid region and flexible circuit block junction, extends the service life of circuit board.
Brief description of the drawings
Fig. 1 is a kind of front view of the anti-rigid-flexible combined circuit plate of folding of the utility model；
Symbol description in figure：
Circuit board body 1, flexible circuit block 2, rigid region 3, flexible fastening piece 4, convex portion 5.
Specific embodiment
Presently in connection with accompanying drawing, the present invention will be described in further detail.
As shown in figure 1, one kind is anti-to roll over rigid-flexible combined circuit plate, including circuit board body 1, the circuit board body 1 includes
Flexible circuit block 2 and the rigid region 3 being positioned close on the top and bottom at the two ends of flexible circuit block 2, the rigid region 3 on the both sides
Opposite end is provided with the anti-extrusion and anti-pull ability of the flexible layers that can effectively improve junction with the junction of flexible circuit block 2
Flexible fastening piece 4, the company of the junction of the flexible fastening piece 4 and rigid region 3 and flexible fastening piece 4 and flexible circuit block 2
It is all arc transition to meet place, can effectively avoid the opposite end of stress concentration, the both sides rigid region 3 from being provided with convex portion 5, convex portion
Groove is formed between 5 and flexible fastening piece 4, the flexible fastening piece 4 is made up of elastic insulator material.
Finally it should be noted that：These implementation methods are merely to illustrate the utility model without limiting model of the present utility model
Enclose.Additionally, to those of ordinary skill in the art, other multi-forms can also be made on the basis of the above description
Change changes.There is no need and unable to be exhaustive to all of implementation method.And thus amplify out it is obvious
Among change or variation are still in protection domain of the present utility model.
