Electroplating refers to the electroplating of one metal on the surface of another metal or non-metal. It has the functions of protection, aesthetics, increasing surface brightness, and increasing mechanical strength. The traditional plating method is to place the item to be plated in a vertical plating bath, adjust the variable plating time under the thickness of the required plating metal layer, and cooperate with the appropriate current density (that is, the unit area passed Current), and placed in a single fixed plating bath for plating. FIG. 1 is a schematic cross-sectional view showing a conventional electric method. Referring to FIG. 1, in a plating bath 100 containing a plating solution and configured with an anode electrode 102, immerse a plating object 106 (such as 11 in FIG. 1) connected to the cathode electrode 104, and adjust it to a Appropriate current density, and after a period of time t of the total plating time, the plated object 10 6 that has been plated is taken out of the electric mine ore grain solution (111 in the first figure). This is the completion of the traditional plating process . Please refer to Table 1. Table 1 lists the maximum thickness and minimum thickness of the plating metal thickness on the surface of the plating object when plating a series of electro-mineral bodies (11 ~ 30) by the traditional plating method, which are consistent with the plating thickness. (Uniformity). According to the data in Table 1, it can be found that the smaller the difference between the maximum and minimum thicknesses of the thickness of the electro-deposited metal on the surface of the electroplated object (Π ~ 30) is, the smaller the surface area of the electro-deposited metal (11 ~ 30) is. The better, the better the consistency. In the same way, when the consistency of the three hundred in table one (please read the notes on the back before filling this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X mm) 475004 A7 2527twf.doc./ 006 ____ B7 V. Description of the invention (2) The larger the ratio, the better the flatness of the plated metal on the surface of the plated object (11 ~ 30). Conversely, when the difference between the maximum and minimum thicknesses of the thickness of the plated metal on the surface of the plated object (Π ~ 30) is larger, or the smaller the percentage of consistency is, it means that the flatness of the plated metal on the surface of the plated object (11 ~ 30) is worse. That is, the less consistent it is. (Please read the notes on the back before filling this page)
