Abstract
The utility model discloses a kind of winding-up etching system, it comprises spray assemblies (1), conveyor track (2) and tuyere (3), with circuit card delivery direction for transverse direction, described spray assemblies (1) is laterally set in qually spaced in transmission track (2) top, and the front correspondence of each spray assemblies (1) is provided with a tuyere (3), described spray assemblies (1) is made up of first shower (4) and two the second showers (5), described the second shower (5) is positioned at the longitudinal both sides of the first shower (1), and the first shower (4) and the second shower (5) are provided with a valve (6).The beneficial effects of the utility model are: it has the advantage that structure is simple, etching efficiency is high and etching quality is good.
Description
Technical field
The utility model relates to etching system, particularly a kind of winding-up etching system.
Background technology
Common etching system comprises shower and transmission track, wherein multiple shower with identical spray flux is positioned at the top of transmission track, transmission track provides the circuit card needing etching, etching solution is provided to etch circuit card to shower, because the spray flux of described multiple shower is identical, the spraying effect of each shower is the same, and the etching solution on circuit card can be made in this case to collect at middle part, cause circuit card to etch uneven, affect the reliability of circuit card.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides the winding-up that a kind of structure is simple, etching efficiency is high and etching quality is good etching system.
The purpose of this utility model is achieved through the following technical solutions: a kind of winding-up etching system, it comprises spray assemblies, conveyor track and tuyere, with circuit card delivery direction for transverse direction, described spray assemblies is laterally set in qually spaced in above transmission track, and the front correspondence of each spray assemblies is provided with a tuyere, described spray assemblies is made up of first shower and two the second showers, the second described shower is positioned at the both sides of the first shower longitudinal direction, and the first shower and the second shower are provided with a valve.
Spacing between the first described shower and the second shower of both sides is equal.
The middle part of the first described shower corresponding circuits plate is arranged, and the two ends of the second shower corresponding circuits plate are arranged.
The air outlet flare shape of described tuyere, the edge of the gas column of blowout and the angle of circuit card place plane are 45 degree to 60 degree.
The utility model has the following advantages: etching system of the present utility model, different with the spray flux of the second shower by the first shower, thus the etching solution making the two ends of circuit card obtain is less than the etching solution that circuit card middle section obtains, therefore the etching solution at the two ends of circuit card constantly flows away along the edge of circuit card, and be provided with tuyere, thus the etching solution of circuit card middle section constantly spreads to two ends under the effect of tuyere, and then the etching solution newly provided directly contacts with in the middle part of described circuit card, etch effect is even, make the reliability of circuit card high, and it also avoid etching solution extended stationary periods and entreat region in the circuit board, cause its over etching, affect circuit card etching quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Fig. 2 is A-A cross-sectional schematic in Fig. 1
In figure, 1-spray assemblies, 2-conveyor track, 3-tuyere, 4-first shower, 5-second shower, 6-valve.
Embodiment
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of winding-up etching system, it comprises spray assemblies 1, conveyor track 2 and tuyere 3, with circuit card delivery direction for transverse direction, described spray assemblies 1 is laterally set in qually spaced in above transmission track 2, and the front correspondence of each spray assemblies 1 is provided with a tuyere 3, as shown in Figure 2, described spray assemblies 1 is made up of first shower 4 and two the second showers 5, the second described shower 5 is positioned at the both sides of the first shower 1 longitudinal direction, and the first shower 4 and the second shower 5 are provided with a valve 6, first shower and the second shower continue spray, in the present embodiment, the spray flux of the first shower 4 is twices of the spray flux of the second shower 5, in circuit card etching process, the etching solution that the two ends of circuit card obtain is less than the etching solution that circuit card middle section obtains, therefore the etching solution at the two ends of circuit card constantly flows away along the edge of circuit card.And then the etching solution of the middle section of circuit card constantly spreads to two ends under the effect of tuyere, and then the etching solution newly provided directly contacts with in the middle part of described circuit card, and etch effect is even, makes the reliability of circuit card high.
In the present embodiment, spacing between the first described shower 4 and the second shower 5 of both sides is equal, the middle part of the first described shower 4 corresponding circuits plate is arranged, and the two ends of the second shower 5 corresponding circuits plate are arranged, thus makes spray identical at the etching solution of circuit card both sides.
In the present embodiment, the air outlet flare shape of described tuyere 3, the edge of gas column and the angle of circuit card place plane of blowout are 45 degree to 60 degree, the blast of tuyere 3 can accelerate the flowing of the etching liquid of middle section, improve the erosion that middle section causes due to the stop of liquid, make the flowing of the etching liquid of circuit board surface more even, thus the circuit that the circuit of the etching of circuit card middle section and neighboring area are etched is equally even, thus improves etching quality.
Working process of the present utility model is as follows: circuit card is under the effect of conveyor track 2, move toward horizontal direction, first shower 4 and the second shower 5 continue spray, in circuit card etching process, the etching solution that the two ends of circuit card obtain is less than the etching solution that circuit card middle section obtains, and therefore the etching solution at the two ends of circuit card constantly flows away along the edge of circuit card.And then the etching solution of the middle section of circuit card constantly spreads to two ends under the effect of tuyere 3, and then the etching solution newly provided directly contacts with in the middle part of described circuit card, and etch effect is even, makes the reliability of circuit card high.
