Description
Technical field
The utility model relates to a kind of flexible circuit board, specifically a kind of flexible circuit board with linear notch.
Background technique
In recent years, electronic product generally appears in every field, and with the update of the development speed in every year generation.
Printed circuit board as electronic product important component is also in continuous perfect, update.And FPC is convenient with its, small, high
Density, high performance feature become printed circuit board Main Trends of The Development.As the improvement of people's living standards, in terms of substance
Therewith there has also been requiring to a certain degree, especially in terms of electronic product, be not only particular about it is practical and attractive, in the volume, integrated of product
The requirement of degree, function etc. is also higher and higher.As industry continues to develop, FPC application field is continuously increased, and demand is continuous
Increase, in order to promote product quality, improves production efficiency, the innovation of traditional technology becomes inevitable trend.
Traditional flexible circuit board surface opening mode, it is higher to job requirements when attaching whole face auxiliary material, operation is imitated
Very big influence is caused in rate.
Utility model content
The utility model provides a kind of flexible circuit board with linear notch, convenient for remaining gas under discharge cover film
And medical fluid, and do not influence surface whole face and attach auxiliary material, operating efficiency is improved, product quality is promoted.
To achieve the above object, the technical solution of the application are as follows: a kind of flexible circuit board with linear notch, including line
Road plate, pure glue-line, release film layer；The wiring board, including substrate layer, cover layer a, cover layer b, in the upper table of substrate layer
Face paste has cover layer a, is pasted with cover layer b, the cover layer a, substrate layer, cover film in the lower surface of substrate layer
Transverse incision is offered on the same vertical plane of layer b；It is pasted with pure glue-line on the cover layer a, is attached in pure glue-line upper surface
There is release film layer.
Further, the shape of the transverse incision is linear.
Further, the transverse incision be located at substrate layer without copper region.
Further, cover layer a, cover layer b are polyimide resin.
Further, pure glue-line is epoxy glue.
Further, release film layer is PVC piece.
Further, cross is offered on multiple same vertical planes of the cover layer a, substrate layer, cover layer b
Notch.
Further, the transverse incision is cut by laser.
The utility model due to using the technology described above, can obtain following technical effect:
1., residual liquor under cover film can be discharged by transverse incision；
2., change hatch frame after, improve operating efficiency, save production cost；
3., avoid reducing the pollution to environment because of waste material caused by traditional opening mode；
4., whole face attach auxiliary material after, traditional approach gummed paper be exposed to outside, easily adhere, generate quality it is bad, change opening
It can be effectively improved after structure, promote auxiliary material quality.
Detailed description of the invention
Fig. 1 is a kind of flexible circuit board overlooking surface perspective view with linear notch；
Fig. 2 is kind of a sectional drawing for the flexible circuit board with linear notch.
Number explanation in figure: 1, release film layer；2, pure glue-line；3, cover layer a；4, cover layer b；5, transverse incision；6,
Substrate layer.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments: as example to this Shen
It please be further described explanation.
As shown in Figs. 1-2, the present embodiment provides a kind of flexible circuit board with linear notch, comprising:
1. release film layer, attached auxiliary material outside product is thin PVC piece using material；
2. pure glue-line is epoxy glue using material for being bonded release film and wiring board；
3. cover layer a is polyimide resin, is located at substrate layer upper surface；
4. cover layer b is polyimide resin；Positioned at substrate layer lower surface；
5. transverse incision, linear notch are provided on multiple same vertical planes of cover layer a, substrate layer, cover layer b；
6. substrate layer is polyimide resin+epoxy glue+copper using material；
The application, which is cut by laser, cuts several openings without copper region to flexible circuit board, can lead to after press presses
It crosses incision air extra under cover film and medical fluid are discharged.Linear notch is attached convenient for the contraposition of whole face auxiliary material and is not had
Glue is postponed opening spilling, can guarantee the quality of auxiliary material while improving production efficiency.
The above, only the utility model create preferable specific embodiment, but the protection that the utility model is created
Range is not limited thereto, and anyone skilled in the art creates the technical scope disclosed in the utility model
Interior, technical solution and its utility model design created according to the utility model are subject to equivalent substitution or change, should all cover
Within the protection scope that the utility model is created.
