Abstract
The utility model provides a carbon film plate with foolproof structures, which comprises a substrate, a conductor layer, a solder mask, an insulating layer and a carbon film layer. At least one group of foolproof structures are arranged on the conductor layer, each group of foolproof structures are arrow structures formed by leads and have reverse angles, and particularly, each group of foolproof structures are respectively '<'-shaped arrow structures and '>'-shaped arrow structures formed of the leads. By the aid of the carbon film plate with the foolproof structures, high-resistance green oil printing direction can be opposite to the arrow direction for printing, and accordingly inspectors can conveniently inspect whether printing directions of printers are correct or not.
Description
[technical field]
The utility model relates to a kind of carbon film plate structure, particularly a kind of carbon film plate structure that can fool proof.
[background technology]
Below the carbon pawl, there is the carbon template of cabling to occur, produces for the carbon template and bring great difficulty, cause original production technology to be abandoned.The challenge of this kind carbon film plate maximum is: when electrical testing, the carbon film of carbon pawl copper conductor very easy and under the carbon pawl links to each other, and tracing it to its cause is that the beneath copper conductor of carbon pawl is irregular distribution, and the probability that the formation broken line turns round in other words under the carbon pawl is very big.If this lead cabling occurs, the chance that occurs skip printing when printing the first road welding resistance increases, and welding resistance and twice high resistant all can't cover full copper cash corner fully, and the carbon oil that finally causes printing carbon film directly is connected with copper cash, the formation short circuit.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of carbon film plate with error-proof structure, and it can check conveniently whether the direction of printing is correct.
The utility model is achieved in that a kind of carbon film plate with error-proof structure, it comprises substrate, conductor layer, solder mask, insulating barrier, carbon film layer, be provided with at least one group of error-proof structure above the described conductor layer, each group error-proof structure is the opposite arrow structure of angle that lead constitutes.
Further, described each group error-proof structure is respectively the arrow structure of " " " type arrow structure and " " " type of lead formation.
Advantage of the present utility model is:
The purpose that the utility model is provided with error-proof structure is that twice high resistant green oil printing of indication is towards the direction printing of side mutually, be reflected on the arrow structure and be exactly: all cover complete printing ink to two arrow structures, perhaps make two arrow structural regions all not have complete covering printing ink (crying " skip printing " in the industry).If one positive one anti-situation (arrow structural integrity covering printing ink, another arrow structure does not have complete covering), can judge that then twice printing all select same direction to print, if be exactly misprint at that rate, therefore high resistant green oil print direction should be selected the direction printing against arrow, and the reviewer can check easily whether printer's print direction is correct like this.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
[embodiment]
See also shown in Figure 1ly, embodiment of the present utility model is described in detail.
As Fig. 1, a kind of carbon film plate 1 of the utility model with error-proof structure, it comprises substrate, conductor layer, solder mask, insulating barrier, carbon film layer, is provided with at least one group of error-proof structure 1 above the described conductor layer, the opposite arrow structure of angle that each group error-proof structure 2 constitutes for lead.In the present embodiment, described each group error-proof structure is respectively " " " type arrow structure 21 and " " " type arrow structure 22 that copper conductor constitutes.
In the production process of carbon film plate 1, need on conductor layer, print solder mask, just print the high resistant green oil.Because copper conductor is irregular distribution, the probability that the formation broken line turns round in other words under the carbon pawl is very big, if this lead cabling occurs, if printing welding resistance the time in the same direction, the chance that occurs skip printing when then printing welding resistance increases, welding resistance and twice high resistant all can't cover full copper cash corner fully, and the carbon oil that finally causes printing carbon film directly is connected with copper cash, forms short circuit.
Therefore the print direction for the high resistant green oil is worthy of careful study, and need print in the opposite direction.Ignore the print direction designing requirement for preventing the printer, the thing that chooses at random print direction takes place, and present embodiment has designed the error-proof structure 2 of at least one group of print direction: " " " arrow structure 21 and " " " arrow structure 22 especially.High resistant green oil print direction should be selected the direction printing against arrow, and the reviewer can check easily whether printer's print direction is correct like this.Because if when printing is along direction of arrow printing, scrape when printing glue and to enter arrow when zone, arrow is scraped with printing glue can form a relative airtight space, the welding resistance in arrow zone can be withstood printing ink because exist bubble to discharge in this space, do not allow printing ink enter this corner of arrow (space), this process just looks like that double sided board directly is placed on plank that to carry out the consent printing on the printing platform the same; On the contrary, if against direction of arrow printing, just do not exist the printing bubble to head on the problem of printing ink, it is the same that this process just looks like that double sided board carries out the consent printing to the plank frame on locating rack.The purpose of fool proof is that the printing of twice high resistant green oil will be towards the direction printing of side mutually, be reflected on " " " arrow structure 21 and " " " arrow structure 22 and be exactly: all cover complete printing ink to two arrow structures, perhaps will make two arrow structural regions all not have complete covering printing ink (crying " skip printing " in the industry).If one positive one anti-situation (promptly an arrow structural integrity covers printing ink, and another arrow structure does not have complete covering printing ink) is that twice printing all selects a direction to print, if be exactly misprint at that rate certainly.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
