Embodiment 1

[0033] Example 1 Preparation of anode phosphor copper ball

[0034] The anode phosphorus copper ball of this embodiment, its copper raw material selects oxygen-free copper, phosphorus raw material selects yellow phosphorus, and specific preparation method comprises the following steps:

[0035] (1) After melting the yellow phosphorus and oxygen-free copper in an intermediate frequency induction furnace, the phosphor copper solution is evenly prepared by stirring in a magnetic stirring tank, and the phosphor copper solution is sent to the holding furnace for storage. The temperature of the holding furnace is 1128 ~ 1135 ℃;

[0036] (2) The phosphor copper solution prepared in step (1) is produced by the upward drawing method to produce a phosphor bronze rod with a diameter of 20-50MM, and the phosphor bronze rod is continuously stamped, and copper balls of different sizes are punched out in different molds;

[0037] (3) After polishing, deburring, cleaning and drying the copp...

Embodiment 2

[0040] Put the anode phosphor bronze ball prepared in Example 1 into the titanium blue and use it normally.

[0041] After one to several months of use, the titanium blue is taken out of the liquid surface. It can be found that the plating solution in the titanium blue anode bag has a fast flow rate and can be drained. Less, indicating that the black film falls off less.

[0042]Moreover, using the anode phosphor bronze balls prepared in Example 1, the anode bag can usually be cleaned once more than six months, the frequency of cleaning the copper ball is reduced by 1 times, the frequency of cleaning the anode bag is reduced by 2 times, the service life of the anode bag is doubled, and the anode The utilization rate can be increased by at least 4%. The utilization rate of copper balls is high, which reduces the cost of tank cleaning and material costs. At the same time, the uniform dissolution of copper balls significantly improves the quality of the coating, and high-quality ...

Abstract

The invention discloses anodic phosphorous copper balls and a preparation method thereof. The method comprises the following steps of: (1) after yellow phosphorus or red phosphorus and oxygen-free copper are melted by adopting a medium-frequency induction furnace, stirring the melt uniformly through a magnetic stirring tank to obtain phosphorous copper solution; (2) producing a phosphorous copper bar with a diameter of 20 to 50 millimeters by using the phosphorous copper solution prepared in the step (1) and an up-draw process, and continuously stamping the phosphorous copper bar to obtain copper balls of different sizes in different dies; and (3) performing polishing, burr removal, cleaning and drying treatment on the copper balls obtained in the step (2) in turn to obtain the anodic phosphorous copper balls. The anodic phosphorous copper balls have the advantages of compact crystal, thin and small crystal grain, high phosphorous copper film generating speed, exquisite and firm phosphorous copper film texture and dropping resistance, and can reduce the cleaning frequency of an anode, effectively improve the utilization rate of the anode and remarkably improve the copper plating effect.

Description

technical field [0001] The invention relates to a metal material processing method, in particular to an anode phosphor copper ball and a preparation method thereof. Background technique [0002] Anode phosphor copper ball is the main electroplating material in the sulfate bright copper plating process, and is the source of copper ions. Under normal circumstances, there is a layer of black oxide film on the surface of phosphor copper anode, referred to as "black film"; the ideal "black film" should be small grains, easy to regenerate and metabolize, rubbing with hands will reveal the true color of copper, and feel fine. slip. [0003] There are many problems in the existing anode phosphor copper balls, such as anode slime and copper powder are too much, which affects the quality of copper plating, reduces the first-time yield, low copper anode utilization, faster consumption of brightener additives, and cleaning of anode bags and copper plating tanks Frequent and other def...
