Abstract
The utility model discloses a kind of flexible circuit board for enhancing pad reliability, including：Flexible circuitry substrate, cover film and pad on the flexible circuitry substrate；The pad includes：Several branch lines that pad main body and one end are connected with the pad main body, the cover film are covered on the flexible circuitry substrate and branch line, and a window is provided on the cover film, and the window area is more than the pad main body area.Using the above program, the utility model need not change the area of pad, and pad is not easily to fall off, enhance the reliability of flexible circuit board, it so that flexible circuit board service life improves, while reduces and is scrapped caused by the reasons such as Pad off, improve yields and CSAT.
Description
Technical field
The utility model is related to flexible circuit board manufacturing field more particularly to a kind of flexible circuitries for enhancing pad reliability
Plate.
Background technology
Flexible circuit board is usually used in the electronic products such as mobile phone, industry control, camera shooting.Entire pad exposes in existing flexible circuit board
Outside cover film, only connecting line is under cover film, and area is small on base material for pad attachment, and pad intensity deficiency is being processed
It is susceptible to pad deformation, Pad off and the situation for falling component in the process with use.
Referring to Fig. 1, prior art cover film 11 only covers circuit 12, the area that pad 13 is attached to base material is small, removes strong
Degree is poor, easy to fall off.
Therefore, the prior art is defective, it is necessary to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of flexible circuitry for enhancing pad reliability
Plate.
The technical solution of the utility model is as follows：A kind of flexible circuit board for enhancing pad reliability, including：Flexible circuitry
Substrate, cover film and pad on the soft line base board.The pad includes：Pad main body and one end with it is described
Several branch lines of pad main body connection, the cover film are covered on the flexible circuitry substrate and branch line, the cover film
On be provided with a window, the window area is more than the area of the pad main body.
Further, the quantity of the branch line is 3.
Further, the leg length is 0.3mm, width 0.3mm.
Further, the distance between the window edge of the cover film and the pad body rim are 0.15mm.
Further, the pad main body is circle.
Using the above program, the utility model need not change the size of pad, and pad is not easily to fall off, enhance flexible circuitry
The reliability of plate so that flexible circuit board service life improves, while reduces and scrapped caused by the reasons such as Pad off, carries
Yields and CSAT are risen.
Description of the drawings
Fig. 1 is the structure diagram of existing pad.
Fig. 2 is the structure diagram of the utility model.
Fig. 3 is the structure diagram of the utility model section.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 2 and Fig. 3 is referred to, the utility model provides a kind of flexible circuit board for enhancing pad reliability, including：It is flexible
Circuit base plate, cover film 1 and pad on the flexible circuitry substrate.The pad includes：Pad main body 4 and one end
Several branch lines 5 being connected with the pad main body 4, a window is provided on the cover film 1, and the window area is more than described
4 area of pad main body.The utility model promotes the stability of pad by increasing flesh branch line on pad, so as to which pad be avoided to take off
Fall this case.
In the present embodiment, the pad main body 4 is circle, and the quantity of the branch line 5 is 3, and the length of the branch line 5 is
0.3mm, width 0.3mm, the window edge of the cover film 1 are with the distance between 4 edge of pad main body d
0.15mm.The cover film 1 can cover the branch 5 and the circuit 2 so that the pad main body 4 is not easily to fall off.
In conclusion the utility model need not change the size of the pad main body 4, the pad is not easily to fall off, enhancing
The reliability of flexible circuit board so that flexible circuit board service life improves, while reduces because the reasons such as Pad off are made
Into scrap, improve yields and CSAT.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement made within new spirit and principle etc., should be included in the guarantor of the utility model
Within the scope of shield.
