Description
Technical field
FPC silk-screen technical fields are the utility model is related to, more particularly to a kind of FPC for being used to examine silk-screen off normal.
Background technology
FPC is widely used in as the printed circuit board (PCB) that a kind of Distribution density is high, in light weight, thickness of thin, bending property are good
Electronics industry.In FPC production processes, it usually needs silk-screen operation, the installation of the setting of silk-screen line to FPC are carried out on FPC
Play positioning action.Generally, ink is printed on FPC by silk-screen line by half tone, but in silk-screen operation process, can there is silk
Linear dimension error is printed, so as to influence FPC assembly precisions.Meanwhile silk-screen line precision can only be tested by secondary element device, work
Make efficiency and production cost is higher.
Utility model content
Main purpose of the present utility model is to propose a kind of FPC for being used to examine silk-screen off normal, it is intended to facilitates staff
Detection to FPC silk-screen line precision, simplify structure, improve operating efficiency, save the production cost of enterprise.
To achieve the above object, the utility model proposes it is a kind of be used to examine the FPC of silk-screen off normal, including FPC substrates,
The FPC substrates include land and logicalnot circuit region.It is used for silk-screen one side on the FPC substrates and is provided with least one silk-screen
Contraposition mark, the silk-screen contraposition mark and the outside silk-screen register guide for being used on the half tone of silk-screen set are sensible corresponding, wherein,
The silk-screen contraposition mark is arranged on the logicalnot circuit region.The silk-screen contraposition mark is arranged to crosswise, and the silk
Print contraposition mark center is provided with the cross silk-screen area for silk-screen.
Preferably, the quantity of the silk-screen contraposition mark is arranged to one.
Preferably, silk-screen contraposition mark erosion carving on the FPC substrates forms.
Compared with prior art, the beneficial effects of the utility model are：Silk-screen contraposition mark is set up on FPC, is changed
Traditional work person, can directly by visual observation by way of detected by Quadratic Finite Element detection device to silk-screen line precision
Mode can be detected, and greatly facilitated the detection work of operating personnel, improved operating efficiency, reduce production cost.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to the structure shown in these accompanying drawings.
Fig. 1 is the utility model FPC structural representations；
Fig. 2 is structural representation after the utility model FPC silk-screens；
Realization, functional characteristics and the advantage of the utility model purpose will be described further referring to the drawings in conjunction with the embodiments.
Embodiment
A kind of FPC for being used to examine silk-screen off normal that the present embodiment proposes, as shown in figure 1, including FPC substrates 1, it is described
FPC substrates 1 include land 6 and logicalnot circuit region 7.On the FPC substrates 1 at least one silk is provided with for silk-screen one side
Print contraposition mark 2, the silk-screen contraposition mark 2 align with the outside silk-screen for being used in the half tone (not shown) of silk-screen set
Identify it is corresponding, wherein, silk-screen contraposition mark 2 is arranged on the logicalnot circuit region 7.The silk-screen contraposition mark 2 is set
Crosswise is set to, and 2 centers of silk-screen contraposition mark are provided with the cross silk-screen area 3 for silk-screen.Further, the silk-screen
The quantity of contraposition mark 2 is arranged to one, and the erosion carving on the FPC substrates 1 of silk-screen contraposition mark 2 forms.
It should be noted that as shown in Fig. 2 in order to ensure the installation accuracy of FPC substrates 1, generally use half tone is by ink
It is imprinted on FPC substrates 1, forms silk-screen line 4, positioned by installation of the silk-screen line 4 to FPC substrates 1.Ensure that silk-screen line 4 arrives
The dimensional accuracy at the edge 8 of FPC substrates 1 can ensure the installation accuracy of FPC substrates 1.Traditional mode is operator by two
Dimension device measuring silk-screen line 4 determines silk-screen dimensional accuracy to the size at the edge 8 of FPC substrates 1, and cumbersome, efficiency is low
Under.In the present embodiment, crosswise silk-screen contraposition mark 2, and the silk-screen are added on the logicalnot circuit region 7 of FPC substrates 1
2 centers of contraposition mark are provided with the cross silk-screen area 3 for silk-screen.It should be noted that each side size in cross silk-screen area 3 is small
In each side size 0.6mm of correspondence of silk-screen contraposition mark 2, further, the size can also be set according to actual tolerance requirements.
The cross silk-screen area 3 is corresponded to, sets up the region for printing cross silk-screen line 5 on half tone simultaneously, and this is used to print cross
Relative position between the region of silk-screen line 5 and region for printing silk-screen line 4 is set according to actual production demand.Right
When FPC substrates 1 are printed, while silk-screen line 4 is printed, cross silk-screen line 5 can be printed on FPC substrates 1, and it is described
The cross silk-screen area 3 that cross silk-screen line 5 is fallen on FPC substrates 1.Due to being used to print the region of silk-screen line 4 on web plate and being used for
Position between the region of printing cross silk-screen line 5 is fixed, if the printing error of silk-screen line 4 is less than the error amount pre-set,
The cross silk-screen area 3 that cross silk-screen line 5 is just fallen on FPC substrates 1, silk-screen is qualified.If the printing error of silk-screen line 4 is beyond advance
The error amount of setting, then cross silk-screen line 5 will not fall completely within the cross silk-screen area 3 on FPC substrates 1, silk-screen is unqualified.Operation
Personnel can observe by the naked eye the relative position between cross silk-screen line 5 and cross silk-screen area 3, easily judge that silk-screen line 4 is
It is no to meet printing precision, so as to substantially increase operating efficiency, production cost has been saved for enterprise.
Preferred embodiment of the present utility model is these are only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
