Abstract
The utility model relates to a flexible wiring board's spider net pad, including circuit board, first net pad and second net pad, circuit board 1 is gone up the symmetry and is provided with first net pad and second net pad, is provided with the cover membrane on the first net pad and windows and the pad, and traditional pad is square pad at the design time usually, and it is strict to pad dimensional requirement, if not pressure welding of the cover membrane dish after the drilling can obtain the pad of required size, but because other trilateral alls of pad expose, produced very easily by the exogenic action and peel off, the utility model discloses study to this problem, provided the design of spider net pad, the problem point of having solved the pad size effectively and easily having peeled off.
Description
Technical field
The utility model relates to circuit pads field, particularly relates to a kind of spidery mesh pad of flex circuit application.
Background technology
Flex circuit application is also called flexible circuit board, or claims flexible printed wiring board.According to the definition of IPC, flexible printed-circuit board is the mode printed, and carries out the product of the designing and making of line pattern on flexible substrate.Use the product of flex circuit application, volume is little, lightweight, greatly the volume of reduction means, is suitable for the needs of electronic product to high density, miniaturization, lightweight, slimming, highly reliable future development.
In prior art, if the patent No. is 201220106961.7, the applying date is 2012.03.21 " induction bonding pad of touch LED light emitter ", this utility model reasonable in design, scientific arrangement, dependable performance.But this utility model still cannot solve pad by the problem being easy to during External Force Acting be peeling, bonding pad area is large, cause cost high, excessive glue simultaneously due to coverlay is unstable, the real size of its pad cannot precisely be decided, therefore for the very high pad of required precision, required precision cannot be reached.
Utility model content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of registration, and materials are saved, and effectively improves the spidery mesh pad of conforming product rate.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of spidery mesh pad of flex circuit application, comprise wiring board, the first grid pad and the second grid pad, it is characterized in that: described wiring board is symmetrically arranged with the first grid pad and the second grid pad, described first grid pad is provided with coverlay and windows and pad.
Further, the spacing of dividing equally between circle and the minor face of pad on described first grid pad is 0.1 millimeter.
Further, the spacing of dividing equally between circle and the long limit of pad on described first grid pad is 0.1 millimeter.
Compared with prior art, the utility model has the advantage of: the utility model is prevent coverlay from overflowing situation that glue and off normal cause pad to diminish, proposes the design of spidery mesh pad, the problem points efficiently solving pad size and easily peel off.
Accompanying drawing explanation
Fig. 1 is circuit board structure figure of the present utility model;
Fig. 2 is grid pad structure figure of the present utility model.
Embodiment
As shown in Figure 1-2, a kind of spidery mesh pad of flex circuit application, comprises wiring board 1, first grid pad 2 and the second grid pad 3; Wiring board 1 is symmetrically arranged with the first grid pad 2 and the second grid pad 3, first grid pad 2 is provided with coverlay to window 21 and pad 22, spacing between the minor face 24 dividing equally circle 23 and pad 22 on first grid pad 2 is 0.1 millimeter, and the spacing of dividing equally between circle 23 and the long limit 25 of pad 22 on the first grid pad 2 is 0.1 millimeter.
The pad of flex circuit application is mainly used for welding component and uses, pad normally strengthens when designing by tradition pad, with drilled coverlay pad pushed down and obtain required pad, the pad of working it out so is normally justified, excessive glue simultaneously due to coverlay is unstable, the real size of its pad cannot precisely be decided, therefore for the very high pad of required precision, this kind of method cannot reach required precision.Such as common at present square pads, it is strict to pad dimensional requirement, the pad that cannot obtain required size by the method for coverlay bond pad of boring, if and boring after coverlay not bond pad, the pad of required size can be obtained, but because other three of pad are all exposed, be easy to be peeling by External Force Acting, the utility model is studied for this problem, propose the design of spidery mesh pad, the problem points efficiently solving pad size and easily peel off.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technical scheme described in foregoing embodiments, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment technical scheme of the utility model.
Claims (3)
