Description
Technical field
Flexible printed circuit board field is the utility model is related to, especially a kind of dismountable FPC.
Background technology
Traditional FPC, such as light bar, due to good plasticity, therefore be usually installed in wall,
The various places such as balcony.But traditional mounting means, it is to paste last layer adhesive glue in the bottom of light bar, followed by the bonding
Light bar is mounted on the various places such as wall, balcony by glue.If when light bar is pulled away its place installed, light bar bottom is attached to
Adhesive glue can then become unable to use, therefore light bar can not be mounted on elsewhere again, and the light bar can then turn into useless part.
Therefore, traditional FPC, there is the defects of not reproducible attachment, is unsatisfactory for the reusable requirement of user.
Utility model content
To solve the above problems, the purpose of this utility model is to provide a kind of dismountable FPC, Neng Goujin
Row repeats to mount, and when needing to change the position of attachment, FPC is pulled away the place of its script installation, and is mounted on new
Place, therefore the defects of can solve the problem that the not reproducible attachment of conventional flex wiring board, so as to meet user couple
The reusable requirement of FPC.
Technical scheme is used by the invention for solving the technical problem：
Dismountable FPC, including mount the flexible magnets layer of function, for forming flexible circuitry for realization
The substrate of the agent structure of plate, the electrical layer for realizing signal transmission and the welding resisting layer for protecting electrical layer, flexible magnets
The adhesive layer for flexible magnets layer and substrate to be bonded is provided between layer and substrate, is set between substrate and electrical layer
It is equipped with the bonding layer for substrate and electrical layer to be bonded, flexible magnets layer, adhesive layer, substrate, bonding layer, electrical layer
Stacked gradually from lower to upper in together with welding resisting layer.
Further, electrical layer is including the pad for welding device, the wire for transmission signal and for as reference
The copper foil of plane, welding resisting layer are covered on electrical layer except the position of pad.
Further, substrate is polyimides film or mylar sheet.
Further, welding resisting layer is that cover layer protects film.
The beneficial effects of the utility model are：Dismountable FPC, by setting flexible magnetic in the lower section of substrate
Iron layer, and the flexible property of flexible magnets layer is utilized, flexible magnets layer can be made to follow substrate arbitrarily to change shape, so that
FPC can arbitrarily be mounted on the place of the magnetic metal of any band；And because the magnetic of flexible magnets layer is made
With, FPC can be carried out repeat attachment so that FPC has removable characteristic, so as to solve
Certainly the defects of the not reproducible attachment of conventional flex wiring board, so as to meet user to the reusable of FPC
Requirement；Adhesive layer can firmly be bonded flexible magnets layer and substrate, therefore when dismantling FPC, it is flexible
Magnet layer can follow substrate to be pulled away together, so, flexible magnets layer can be located among FPC, so that
Obtaining FPC can carry out repeating attachment.
Brief description of the drawings
The utility model is described in further detail with example below in conjunction with the accompanying drawings.
Fig. 1 is the diagrammatic cross-section of dismountable FPC of the present utility model.
Embodiment
Reference picture 1, dismountable FPC of the present utility model, including for realizing the flexible magnets of attachment function
Layer 1, the substrate 2 of agent structure for forming FPC, the electrical layer for realizing signal transmission and for protecting electricity
The welding resisting layer 4 of gas-bearing formation, it is provided between flexible magnets layer 1 and substrate 2 for flexible magnets layer 1 and substrate 2 to be bonded
Adhesive layer 5, the bonding layer 6 for substrate 2 and electrical layer to be bonded is provided between substrate 2 and electrical layer, it is flexible
Magnet layer 1, adhesive layer 5, substrate 2, bonding layer 6, electrical layer and welding resisting layer 4 stack gradually in together from lower to upper.It is arranged at base
The flexible magnets layer 1 of the lower section of plate 2, has good flexible property, the deformation of substrate 2 can be followed arbitrarily to change shape, therefore
FPC is enabled to arbitrarily to be mounted on the place of the magnetic metal of any band.And the magnetic of flexible magnets layer 1
Effect, it can make FPC that there is the effect for repeating attachment.Such as FPC is mounted on a certain irony position, when with
When family needs to change the mounting position of FPC, FPC need to only be pulled away the position of its script attachment, and soft
The flexible magnets layer 1 of property wiring board is directed at new another irony position, that is, completes the mistake of dismounting and the attachment of FPC
Journey, therefore, FPC of the present utility model have removable characteristic, can solve the problem that can not weighing for conventional flex wiring board
The defects of mounting again, so as to meet reusable requirement of the user to FPC.Adhesive layer 5 can be flexibility
Magnet layer 1 and substrate 2 are firmly bonded, therefore when FPC is disassembled, flexible magnets layer 1 can follow substrate 2
Pulled away together, so, flexible magnets layer 1 can be located among FPC, so that FPC energy
Enough carry out repeating attachment.
Wherein, reference picture 1, electrical layer include being used for the pad 31, the wire 32 for transmission signal and use for welding device
In copper foil 33 as a reference plane, welding resisting layer 4 is covered on electrical layer except the other positions of pad 31, welding resisting layer 4 are
Cover layer protects film.Cover layer protection film can not only prevent from welding, and also have the function that insulation, can avoid outside
The problem of powered object causes FPC to burn because of touching FPC.
Wherein, reference picture 1, substrate 2 are polyimides film or mylar sheet.By polyimides film or polyester
The substrate 2 that film film is formed, has height reliability and excellent pliability, therefore, FPC tool of the present utility model
There is the characteristics of high Distribution density, in light weight, thickness of thin and bending property are good, be very suitable for the making of light bar.
When making light bar using FPC of the present utility model, LED lamp bead is also welded in the weldering in electrical layer
On disk 31, and wire 32 then can provide working power for LED lamp bead.Mounted when being mounted to light bar, such as light bar
On irony support, only need to the LED lamp bead in light bar outwardly, while flexible magnets layer 1 be directed at irony support and light bar
It is positioned on irony support, light bar can be securely fastened to iron by the magnetic effect between flexible magnets layer 1 and irony support
On matter support.When user needs to change mounting position to light bar, only light bar need to be pulled away irony support, you can complete dismounting
Operation, now, light bar still has good mount capability, and then, user is directed at the flexible magnets layer 1 in light bar new
Mounting position is simultaneously positioned over light bar on new mounting position, that is, completes reinstalling for light bar.Therefore, using this practicality
The light bar that new FPC makes, the defects of can solve the problem that the not reproducible attachment of conventional lights band, so as to meet
Reusable requirement of the user to light bar.
Above is to it is of the present utility model preferably implement illustrated, but the utility model be not limited to it is above-mentioned
Embodiment, those skilled in the art can also make a variety of be equal on the premise of without prejudice to the utility model spirit
Deformation is replaced, and these equivalent deformations or replacement are all contained in the application claim limited range.
