Abstract
The utility model discloses a FPC with two -sided silk screen printing is counterpointed and is marked, the FPC who aim at providing a simple structure, the counterpoint precision is high, the printing quality is high has two -sided silk screen printing counterpoint sign. The utility model discloses a base plate (1), the upper surface of base plate (1) is equipped with a plurality of upper surface silk screen printing counterpoint sign (2), the lower surface of base plate (1) is equipped with a plurality of lower surface silk screen printing counterpoint sign (3), upper surface silk screen printing counterpoint sign (2) with underlap in the vertical direction of lower surface silk screen printing counterpoint sign (3). The utility model discloses be applied to FPC's technical field.
Description
Technical field
The utility model relates to a kind of FPC, particularly a kind of FPC with double-surface screen printing alignment mark.
Background technology
Flexible PCB (FPC) is that the one made for base material with polyimides or polyester film has height reliability, excellent flexible printed circuit, has the advantages that distribution density is high, lightweight, thickness is thin, bending property is good.FPC finished product often stamps character literal etc. according to relevant requirement, and the general mode of silk-screen that uses is printed at present.When silk-screen contraposition, adopt one side mark circle to carry out contraposition, this alignment mode precision is not high.Misplace to a certain extent because two-sided FPC exists in addition, thus the word printed can be caused to misplace, affect product appearance, reduce quality.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides the FPC with double-surface screen printing contraposition mark that a kind of structure is simple, aligning accuracy is high, press quality is high.
The technical scheme that the utility model adopts is: the utility model comprises substrate, the upper surface of described substrate is provided with several upper surface silk-screen contrapositions mark, the lower surface of described substrate is provided with several lower surface silk-screen contrapositions mark, not overlapping on the vertical direction that described upper surface silk-screen contraposition mark and the contraposition of described lower surface silk-screen identify.
Further, described upper surface silk-screen contraposition mark comprises annulus and spider, described spider be centrally located at described round Ring current distribution.
Further, described lower surface silk-screen contraposition mark comprises annulus and spider, described spider be centrally located at described round Ring current distribution.
Further, described annulus and described spider all form at described substrate attack engraving.
The beneficial effects of the utility model are: because the utility model have employed the design of double-surface screen printing contraposition mark, the utility model comprises substrate, the upper surface of described substrate is provided with several upper surface silk-screen contrapositions mark, the lower surface of described substrate is provided with several lower surface silk-screen contrapositions mark, not overlapping on the vertical direction that described upper surface silk-screen contraposition mark and the contraposition of described lower surface silk-screen identify, so, the utility model can the independent contraposition in two sides when silk-screen contraposition, substantially increase the precision of silk-screen, structure is simple, and press quality is high.
Accompanying drawing explanation
Fig. 1 is partial side elevation view of the present utility model;
Fig. 2 is top partial view diagram of the present utility model.
Embodiment
As depicted in figs. 1 and 2, the utility model comprises substrate 1, the upper surface of described substrate 1 is provided with several upper surface silk-screen contrapositions mark 2, the lower surface of described substrate 1 is provided with several lower surface silk-screen contrapositions mark 3, not overlapping on the vertical direction that described upper surface silk-screen contraposition mark 2 and the contraposition of described lower surface silk-screen identify 3.
In the present embodiment, described upper surface silk-screen contraposition mark 2 comprises annulus and spider, described spider be centrally located at described round Ring current distribution, described annulus and described spider all form at described substrate 1 erosion carving.
In the present embodiment, described lower surface silk-screen contraposition mark 3 comprises annulus and spider, described spider be centrally located at described round Ring current distribution, described annulus and described spider all form at described substrate 1 erosion carving.
When silk-screen, the two sides due to FPC is equipped with contraposition mark, and by identify 2 respectively with the contraposition of described upper surface silk-screen, the contraposition of described lower surface silk-screen identifies 3 contrapositions, makes printing word icon on FPC very precisely, greatly can improve the quality of product.
The utility model is applied to the technical field of FPC.
Although embodiment of the present utility model describes with practical solution, but the restriction do not formed the utility model implication, for those skilled in the art, according to this specification to the amendment of its embodiment and and the combination of other schemes be all apparent.
Claims (5)
1. one kind has the FPC of double-surface screen printing alignment mark, comprise substrate (1), it is characterized in that: the upper surface of described substrate (1) is provided with several upper surface silk-screen contrapositions mark (2), the lower surface of described substrate (1) is provided with several lower surface silk-screen contrapositions mark (3), not overlapping on the vertical direction that described upper surface silk-screen contraposition mark (2) and the contraposition of described lower surface silk-screen identify (3).
2. a kind of FPC with double-surface screen printing alignment mark according to claim 1, is characterized in that: described upper surface silk-screen contraposition mark (2) comprises annulus and spider, described spider be centrally located at described round Ring current distribution.
