Abstract
The utility model discloses a kind of flexible PCB, including flexible PCB body, upper and lower two sandwich circuit is provided with the flexible PCB body, the flexible PCB body has flex area, and the position corresponding with the flex area of upper and lower two sandwich circuit sets grid copper.The utility model flexible PCB is designed using two-layer wiring, can so reduce quantity punched during the outlet inside connector, the width that cabling takes when can also reduce horizontal outlet；Grid copper is set in the position corresponding with flex area of upper and lower two sandwich circuit, the hardness of this subregion is reduced so that this subregion softens, it is ensured that bending.
Description
Technical field
The utility model is related to flexible PCB field.
Background technology
Nowadays, with the popularization of Wearable product, associated flexible board design is also growing day by day, because Wearable is universal
Weight small volume, portative feature, cause when designing flexible PCB, wiring space is restricted.Work as flexible PCB
The connector PIN numbers used are on the high side, and when going out line width relative narrower, design bottleneck will occur.
In order to solve this problem, some flexible PCBs are designed using two-layer wiring, can so reduced in connector
Punched quantity during internal outlet, the width that cabling takes when can also reduce horizontal outlet.But because having bilayer in bent area
Cabling, can make bent area part really up to the mark, reduction bending property, increase bounce.
Utility model content
For the problems of the prior art, the purpose of this utility model is to provide a kind of flexible PCB, existing to solve
When having in technology using two-layer wiring design so that bent area part is really up to the mark, reduction bending property, the problem of increasing bounce.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of flexible PCB, including flexible PCB body, it is characterised in that set on the flexible PCB body
Have upper and lower two sandwich circuit, the flexible PCB body has a flex area, upper and lower two sandwich circuit with the flex area
Corresponding position sets grid copper.
It is preferred that, the flexible PCB body is followed successively by dielectric film, upper layer circuit, flexible parent metal, lower floor from top to bottom
Circuit, dielectric film.Further, the dielectric film is PI cover layers.Or, the dielectric film is PET polyester films.
It is preferred that, the surface of the dielectric film is arranged at intervals with raised line, and the direction of raised line is parallel with bending part.
The utility model flexible PCB is designed using two-layer wiring, is beaten when can so reduce the outlet inside connector
The quantity of via, the width that cabling takes when can also reduce horizontal outlet；In the corresponding with flex area of upper and lower two sandwich circuit
Position set grid copper, reduce the hardness of this subregion so that this subregion soften, it is ensured that bending.
The surface of dielectric film is arranged at intervals with raised line, and the direction of raised line is parallel with bending part so that dielectric film is local
Thickness is thinning, and the place of thinner thickness is more flexible, is further ensured that the bending of flex area.
The characteristics of the utility model, see the detailed description of this case schema and following preferable embodiment and obtain clear
Ground understands.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
The utility model is expanded on further in face in conjunction with specific embodiments.
Referring to Fig. 1, a kind of flexible PCB, including flexible PCB body 10, flexible PCB body 10 is from top to bottom
It is followed successively by dielectric film 11, upper layer circuit 12, flexible parent metal 13, lower sandwich circuit 14, dielectric film 15.Dielectric film 11 and dielectric film 15 are equal
PI cover layers or PET polyester films can be selected.This two-layer wiring design, it is possible to reduce beaten inside connector during outlet
The quantity of via, the width that cabling takes when can also reduce horizontal outlet.
Flexible PCB body has flex area 16, and the position corresponding with flex area of upper and lower two sandwich circuit uses net
Lattice copper 17 replaces original entity copper.Reduce the hardness of this subregion so that this subregion softens, it is ensured that bending.
In addition, the surface of dielectric film is arranged at intervals with raised line 18, and the direction of raised line 18 is parallel with bending part.So that absolutely
Velum local thickness is thinning, and the place of thinner thickness is more flexible, is further ensured that the bending of flex area.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply principle of the present utility model, the utility model also has respectively on the premise of the utility model spirit and scope are not departed from
Changes and improvements are planted, these changes and improvements are both fallen within the range of claimed the utility model.The utility model requirement
Protection domain defined by appended claims and its equivalent.
