Abstract
The utility model provides a kind of flexible circuit board, including material main body and the pad for extending the material main body, the pad includes first surface and the opposite second surface of the first surface, the flexible circuit board further includes the substrate extension extended from the material main body to pad, and the substrate extension covers at least partly region of the first surface.The flexible circuit board of the utility model enhances the toughness of welding disking area by setting substrate extension, can prevent welding disking area from bending fracture occurs.
Description
Technical field
The utility model relates to circuit board technology field, in particular to a kind of flexible circuit board.
Background technique
Flexible circuit board (Flexible Printed Circuit Board, FPCB) is made of insulating substrate flexible
Printed circuit board, have the advantages that many rigid printed circuit boards do not have.For example, flexible circuit board can with free bend,
Winding folds, and can require any arrangement according to space layout.The volume of electronic product can be substantially reduced using flexible circuit board,
It is applicable in the needs that electronic product develops to high density, miniaturization, highly reliable direction.Therefore, flexible circuit board space flight, military affairs,
It is widely used on the fields such as mobile communication, laptop computer, computer peripheral equipment, PDA, digital camera or product.
However, the toughness of welding disking area is poor since the pad of flexible circuit board extends substrate, occur to be easy when bending
Fracture.
Thus, it is necessary to be improved to flexible circuit board, to avoid drawbacks described above.
Utility model content
The purpose of the utility model is to provide one kind can prevent welding disking area from the flexible circuit board that bending is broken occurs.
In order to achieve the above objectives, the utility model is the following technical schemes are provided: a kind of flexible circuit board, including material main body
With the pad for extending the material main body, the pad includes first surface and second table opposite with the first surface
Face, the flexible circuit board further include the substrate extension extended from the material main body to the pad, and the substrate extends
Portion covers at least partly region of the first surface.
Preferably, the substrate extension extends along the edge of the pad.
Preferably, the substrate extension extends to the end far from the material main body of the pad.
Preferably, the width of the substrate extension is 0.35mm.
Preferably, the material main body and the substrate extension are integrally formed.
Preferably, the material main body and the material of the substrate extension are polyimides.
The utility model has the following technical effect that the flexible circuit board of the utility model passes through setting substrate extension,
The toughness of welding disking area is enhanced, can prevent welding disking area from bending fracture occurs.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of flexible circuit board provided by the utility model；
Fig. 2 is the structural schematic diagram of vertical view the visual angle substrate extension and pad of the flexible circuit board of Fig. 1.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
All other embodiment obtained, fall within the protection scope of the utility model.
It as depicted in figs. 1 and 2, is flexible circuit board 1 provided by the utility model.The flexible circuit board 1 includes substrate
Ontology 11 and the pad 21 for extending the material main body 11.
The pad 21 includes first surface 211 and the second surface 212 opposite with the first surface 211, and described the
One surface 211 and the second surface 212 are exposed to the material main body 11.The first surface 211 and/or second table
Welding surface of the face 212 as pad solder.
The flexible circuit board 1 further includes the substrate extension 12 extended from the material main body 11 to the pad 21,
The substrate extension 12 covers at least partly region of the first surface 211.Preferably, the material main body 11 and described
The material of substrate extension 12 is polyimides, and further, the material main body 11 and the substrate extension 12 can be with one
It is body formed.
Since the substrate extension 12 covers at least partly region of original exposed pad, only have compared to original
The setting of the case where pad, the substrate extension 12 enhance the toughness of welding disking area.Increase in view of toughness is better achieved
The end far from the material main body 11 that the substrate extension 12 extends to the pad 21 can be set in strong purpose
210.In view of influence of the setting to pad solder of the substrate extension 12, it is preferred that the substrate extension 12 is along institute
The edge for stating pad 21 extends.In view of toughness enhances and reduces the influence to pad solder, the width of the substrate extension 12
Degree is preferably arranged to 0.35mm.
The flexible circuit board of the utility model enhances the toughness of welding disking area, Neng Goufang by setting substrate extension
Only bending fracture occurs for welding disking area.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other relevant technical fields, are also included in the patent protection scope of the utility model.
