Fig. 1 is a kind of structural schematic diagram of the Rigid Flex provided in the utility model embodiment.
Specific embodiment
In order to make those skilled in the art better understand the technical solution of the utility model, with reference to the accompanying drawing and have
The utility model is described in further detail for body embodiment.
Referring to Fig. 1, Fig. 1 is the structural schematic diagram of one kind provided by the embodiment of the utility model.
A kind of Rigid Flex provided by the embodiment of the utility model, comprising:
First flexible circuit board 1, the second flexible circuit board 2 and printed circuit board 3, the of first flexible circuit board 1
One end face is fixedly installed in the first end face of printed circuit board 3, the first end face fixed setting of second flexible circuit board 2
In in the second end face of the printed circuit board 3；The second of first flexible circuit board 1 and second flexible circuit board 2
End face is used to welding electronic component.
It should be noted that printed circuit board 3 (full name in English: Printed Circuit Board, English abbreviation:
PCB), it is important electronic component, is the supporter of electronic component, is the carrier of electronic component electrical connection.Due to it
It is to be made of electron printing, therefore referred to as " print " circuit board, may be also generally referred to as " hardboard ".Printed circuit board 3
On can be welded with electronic component, i.e., printed circuit board 3 can be circuit board original and required in mobile terminal.Printing
Circuit board 3 realizes its function in addition to being welded with electronic component, is also used as support plate and is set to the first flexible circuit board 1
And second between flexible circuit board 2 so that the first flexible circuit board 1 and the second flexible circuit board 2 can burn-on electronics member device
Part.
It is understood that flexible circuit board (Flexible Printed Circuit abbreviation FPC) is with polyimides
Or polyester film is that one kind made of substrate has height reliability, excellent flexible printed circuit 3 has Distribution density
Feature high, light-weight, thickness is thin and bending is good, also commonly referred to as " soft board ".Since flexible circuit plate thickness is thin and
The good feature of bending, can not carry the electronic component on two sides on flexible circuit board, stamp electronics member device on one side wherein
Electronic component is beaten on another face again after part to be easy to cause flexible circuit board to damage, therefore is typically only capable in flexible electrical
Electronic component is stamped on one face of road plate.When needing to stamp more electronic component on flexible circuit board, flexible electrical
Plate occupied area in road is larger, affects the topology layout inside mobile terminal.
It should be noted that the wiring board in the utility model embodiment is mainly used in the internal structure of mobile terminal
In, such as the mobile terminals such as smart phone, tablet computer and laptop.Due to soft by the first flexible circuit board 11 and second
The two sides for the circuit board that property circuit board 22 is combined into can carry electronic component, that is, the electronics member device for the circuit board bearing being combined into
Part is twice of the electronic component that original flexible circuit board is carried, therefore the circuit board being combined into only accounts for original flexible electrical
One semi-area of road plate, effectively saves the space inside mobile terminal, is advantageously implemented the lightening of mobile terminal.
Optionally, the first end face of first flexible circuit board 1 is fixedly attached at the printing electricity by non-conductive adhesive 4
In the first end face of road plate 3, the first end face of second flexible circuit board 2 is fixedly attached at the print by non-conductive adhesive 4
In the second end face of printed circuit board 3.It should be noted that the first flexible circuit board 1, printed circuit board 3 and the second flexible electrical
Circuit connection can also be got up by via hole technique between road plate 2 so that the first flexible circuit board 1, printed circuit board 3 with
And the second partial circuit between flexible circuit board 2 can be interconnected.Wherein, via hole is also referred to as plated through-hole, in the first flexibility
In circuit board 1, printed circuit board 3 and the second flexible circuit board 2, for the printed conductor being connected between each circuit board, in each electricity
A upper common aperture, i.e. via hole are bored by the intersection for the conducting wire that road plate needs to be connected to.It, can on the hole wall cylindrical surface of via hole in technique
To plate one layer of metal with the method for chemical deposition, the copper foil for needing to be connected to be connected to intermediate each circuit board, and via hole is upper
Lower two sides is made into circular pad shape, the parameter of via hole mainly porose outer diameter and bore size.
Optionally, the partial region of the first end face of first flexible circuit board 1 is fixedly installed on the printed circuit
In the first end face of plate 3, the partial region of the first end face of second flexible circuit board 2 is fixedly installed on the printed circuit
In the second end face of plate 3.
Optionally, first flexible circuit board 1 and second flexible circuit board 2 are double-layered circuit board or multilayer line
Plate.It should be noted that flexible circuit board is divided according to the number of plies of copper-foil conducting electricity, it is divided into lamina, doubling plate and multi-layer board etc..
The structure of lamina: the flexible board of this structure is the flexible board of simplest structure.Usual structure are as follows: substrate+transparent adhesive tape+copper foil
+ protective film+transparent adhesive tape.Firstly, the circuit that copper foil process such as will perform etching to be needed, protective film will drill
To expose corresponding pad.The two is combined with rolling process again after cleaning.Then it is electroplated again in the pad portion of exposing
Gold or tin etc. are protected.When the route of circuit is too complicated, lamina can not be routed or needs copper foil to carry out earth shield,
It just needs to select doubling plate even multi-layer board.Multi-layer board and the most typical difference of lamina are to increase via structure to link
Each layer copper foil.In order to guarantee that the first flexible circuit board 1 and the second flexible circuit board 2 are not connected with printed circuit board 3, this is practical new
It can be selected to use doubling plate or multi-layer board according to the actual needs of mobile terminal in type embodiment.
A kind of Rigid Flex provided by the utility model is described in detail above, for the general of this field
Technical staff, based on the idea of the embodiment of the present invention, there will be changes in the specific implementation manner and application range,
In conclusion the content of the present specification should not be construed as a limitation of the present invention.
