Abstract
The utility model discloses a deep-hole simulated electroplating experimental tank which is used for electroplating technology research and plating solution performance testing. Since the straight foot of the cathode right-angle foot test piece is arranged in the hole of the wall of the cathode of the electroplating experimental tank, the hole shields the power line, the current density on the right-angle foot is greatly lowered, and the current density difference between the hole and the right-angle foot is enlarged, i.e. the current density high area/low area ratio is enlarged, so that the experimental test piece with limited length has a wider current density range, thereby widening the testing range. The hole and the right-angle foot are formed, and the current density level area and the observation window are added to the test piece, thereby enhancing the testing functions and precision. On the premise of maintaining the original functions and actions of the Hall tank, the utility model increases the experimental functions in research and testing of uniformity of complex-geometric-shape coating, microporous electroplating filling of printed circuits and the like. The experimental tank and the test piece are economic to manufacture, and simple and convenient to use.
Description
Technical field:
The utility model relates to electroplating technology research, electroplating solution performance test, especially relates to the test set that complex geometry coating degree of uniformity, printed electronic circuit (PCB) micropore filling ability are characterized.
Background technology:
The test set that is used for the electroplating technology aspect has many, and main commonly used be Hull Cell, see version " electroplating solution and coating performance test " the 123rd page in 2003, because the test piece of Hull Cell negative electrode is subjected to limitation of length, the current density range of its displaying is narrower, the ratio that is the high district of current density/low district is lower, the strength of current that adopts of experiment makes the plating density that shows may be not in the scope of actual requirement, the in addition impact of tested plate plane shape, can only show the coating situation in a certain current density range section, and can not depth show coating situation on a certain current density point, so to some complex geometry coating uniformity coefficient, the research test of PCB micropore filling ability is just not too applicable.
Summary of the invention:
The purpose of this utility model provides a kind of deep hole simulation electroplating experimental bath, enlarges the test specification of current density in the negative electrode test piece, increases current density and shows window, the deficiency that the planar cathode test piece of solution Hull Cell exists.
The technical scheme that the utility model adopts is: deep hole simulation electroplating experimental bath is improved by Hull Cell and forms, keep Hull Cell yin, yang pole distance and cathode wall length and placement gradient constant, cathode wall is expanded thick 15 millimeters～24 millimeters, at wall 1～10 rectangular through-hole is set, its aperture is wide 6 millimeters～and 10 millimeters, high 4 millimeters～24 millimeters, place negative electrode right angle pin test piece in cathode wall, its pin places in the rectangular opening.Owing to the formation of hole and pin, increased level zone and the current density impression window of current density.
Cathode wall in the deep hole simulation electroplating experimental bath has two kinds of settings; Fixed: as will to choose the cathode wall of hole figure place and aperture specification, permanent being fixed on the desired location.Movable: the desired location of cathode wall in experimental tank, adopt the setting of loading onto and discharging, be convenient for changing like this cathode wall of different size type.
The material of the negative electrode right angle pin test piece that deep hole simulation electroplating experimental bath adopts, thickness and length and width size are identical with the used test piece of Hull Cell, thereunder utilize 1～10 of test piece material of main part making to be 90 degree and stretch to consistent pin, 6 millimeters～10 millimeters of pin minor faces, 15 millimeters～24 millimeters on long limit.Because the pin of negative electrode right angle pin test piece places in the hole of electroplating experimental bath cathode wall, the aperture is to the shielding of power line, current density on the pin significantly reduces, the difference of the current density of aperture and pin enlarges, be that the high district of current density/low district ratio enlarges, make the negative electrode right angle pin test piece of limited length can show wider current density range.Add hole with the benefit that pin forms, jointly enlarged test specification and improved test function and precision.
The beneficial effects of the utility model are: when keeping the effect of Hull Cell experiment original function, enlarge current density and showed scope, current density level zone and viewing window have been increased, the implicit content that some can't be represented in the Hull Cell experiment can be out tested, increased experiential function and improved test mass.
