Problems solved by technology

This kind of phosphor bronze ball with a smooth surface is prone to the following problems when it is used in electroplating: 1. The surface area of ​​the phosphor bronze ball is fixed, and only fixed copper ions can be released from the surface of the phosphor bronze ball; Each part of the copper ball forms a phosphorus film because of the different phosphorus content of each part, and the formation of the phosphorus film has a speed; Phosphorus film is produced, so it is necessary to waste the copper ions used in advance; 4. When using large currents, due to the fixed surface area of ​​phosphor copper balls, only copper balls with larger surface areas can be selected, so the size of phosphor copper balls becomes larger; 5. Due to It is a solid phosphor bronze ball with a smooth surface, and its quality is heavy and its cost is high

Embodiment Construction

[0024] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0025] The surface of this embodiment has phosphor bronze balls with grooves, such as figure 1 As shown, it includes a phosphor bronze ball body 1 and grooves 10 arranged at intervals on the surface of the phosphor bronze ball body 1, the grooves 10 are evenly distributed on the entire surface of the phosphor bronze ball body 1, the shape is hemispherical, and all the grooves The centers of 10 are all on the same spherical surface.

[0026] The preparation method of the above-mentioned phosphor bronze ball with grooves on the surface is as follows:

[0027] The copper raw material is electrolytic copper or bright copper with a copper content of 99.99%, and the phosphorus raw material is a phosphor-bronze master alloy with a phosphorus content of 5-15% by mass, which specifically includes the following steps:

[0028] (1)...

Abstract

The invention discloses a phosphor copper ball with grooves at the surface and a preparation method thereof. The phosphor copper ball comprises a phosphor copper ball body, and grooves arranged at the surface of the phosphor copper ball body at intervals, and the height difference between the bottoms of the grooves and the surface of the phosphor copper ball body is 1-3mm. Compared with the existing solid phosphor copper ball which is smooth and flat in surface, the phosphor copper ball with the grooves at the surface provided by the invention has large superficial area, can bear greater current, discharges more copper ions in the electroplating process, and is high in usage rate.

Description

technical field [0001] The invention relates to a phosphor copper ball with grooves on the surface for electroplating and a preparation method thereof. Background technique [0002] Anode phosphor copper ball is the main electroplating material in the copper plating process, and it is the source of copper ions. The phosphor-bronze balls prepared by the existing method for preparing phosphor-bronze balls for electroplating are all solid phosphor-bronze balls, and the surfaces of the phosphor-bronze balls are smooth and even. This kind of phosphor bronze ball with a smooth surface is prone to the following problems when it is used in electroplating: 1. The surface area of ​​the phosphor bronze ball is fixed, and only fixed copper ions can be released from the surface of the phosphor bronze ball; Each part of the copper ball forms a phosphorus film because of the different phosphorus content of each part, and the formation of the phosphorus film has a speed; Phosphorus film i...
