Description
The present invention is the device and method that is applied to the control electric force lines distribution on the electroforming process for a kind of.
Generally on ink cartridges nozzle piece technology, for in the control of the aperture of nozzle bore, major part can be average by adding masking shield or utilize the metallic conduction characteristic, make in technology the metallic diaphragm of being piled up, thereby the approaching ± 3 μ m of hole tolerance energy, can be uniform and stable to guarantee the ink spray volume.
As shown in Figure 1, after utilizing galvanic current to make anode metal on the positive plate 11 produce oxidizing reaction in the electrotyping bath to become metal ion, because of being subjected to the field of electric force effect between this positive plate 11 and a negative plate 12, to form power line 13, again this power line 13 be subjected to electric current distribution and conduction time length influence, the intensive more then formed power line of electric current distribution is also many more, causes metal ion to be reduced into atoms metal and forms and arrange the situation of piling up and the zone that these several power lines 13 are concentrated is easy more.The emission of this power line 13 and none fixed position again, thereby if there is not the masking shield of this power line 13 of control, then have the situation of these power line 13 skewness to take place, and its metal accumulation can be subjected to the field of electric force distribution influence, the phenomenon that causes the accumulation degree to have thickness to differ.And because of being subjected to the effect of fringing effect on this negative plate 12, potential difference is bigger, and electric field is stronger, and therefore, if the control of no masking shield, then the formed metallic diaphragm in edge can be than thick middle.
At above shortcoming, the prior art for example wild neat Japanese application for a patent for invention publication number that waits the people of virtue is the method that the Chinese utility application of 91205260.0d has worked out another kind of solution for people's such as the special application case of opening flat 5-25676 and Chen Xiaojuan application number, see also Fig. 2 (a) (b), in a positive plate 21 and a negative plate 22, add a single hole masking shield 24 between 221, power line 23 can be concentrated earlier by this single hole masking shield 24 to be emitted on this negative plate 221 again, can be increased in this negative plate 22 whereby, 221 intermediary projection probability, with improve because of fringing effect cause at this negative plate 22, the formed metal level in 221 edges can be than the problem of thick middle, and through test, its result shows: differ ± 10 μ m with the edge in the middle of it, with ideal value ± 3 μ m still have gap, so its qualification rate is not good.
From the above, there is following shortcoming in prior art:
1. the metallic diaphragm uneven thickness on this negative plate.
2. utilize this single hole masking shield, can cause the big multidirectional intermediate distribution of this metallic diaphragm on the contrary, cause this metallic diaphragm distribution range too small.
Another known techniques, for example the wild neat Japanese patent of invention publication number that waits the people of virtue number is 91205260.0 application case for people's such as the special application case of opening flat 5-25676 and Chen Xiaojuan Chinese utility model application, and it is to utilize a special former dish bracing frame to carry out the electroforming program.The former dish peripheral portion that is supported at former dish bracing frame will be provided with the supporting electrode more than 1 at least, and utilize different voltage differences to put on former dish and anode with between auxiliary cathode and the anode, to carry out the electroforming program, the power line that can prevent peripheral portion is by this concentrated, and the electroforming film thickness difference on the former dish is diminished.If but voltage difference V1 is when bigger than voltage difference V2, can't prevent concentrating of former dish peripheral portion power line, if voltage difference V2 is more obvious when big than voltage difference V1, can't separate out former dish, therefore, the best relation of current potential size V1 and V2 be V2 than V1 a little more greatly, and V2 is than 1.5 times little of V1, so this known techniques needs CONTROLLED POTENTIAL difference V1 and V2.
