Problems solved by technology

Solid phosphor bronze balls are prone to the following problems during electroplating: 1. Copper ions can only be released from the surface of phosphor bronze balls; 2. The generated anode slime will easily cover the surface of phosphor bronze balls to prevent the release of copper ions , reduce the utilization rate of phosphor bronze balls, and the waste is serious; 3. Because they are solid, the quality of phosphor bronze balls is heavy and the cost is high, while some hollow phosphor bronze balls have low compressive capacity and are easy to damage and phosphor bronze balls There are often uneven and dull phenomena. Therefore, it is necessary to invent an electroplated anodic phosphor copper ball and its preparation method to solve the above problems

Abstract

The invention discloses an electroplating anode phosphorus copper ball and a preparation method thereof. The electroplating anode phosphorus copper ball comprises a ball body; a hollow groove is formed in the ball body; reinforcing rings are encircled around the outer side of the hollow groove; and projection blocks are encircled around the outer sides of the reinforcing rings. Hydrogen peroxide is added in a reaction kettle, and can oxidize copper powder to improve the phenomenon of looseness, unevenness and no luster of a cathode deposition layer caused by uniform deposition of Cu+ on a loose crystal and to improve the service life and the beauty of the phosphorus copper ball; through continuous stirring of melts, uniform distribution of phosphorus elements is guaranteed, so that the purposes of compact crystallizing particles and compact structure are achieved, and formation of monovalent copper ions is effectively inhibited; and phosphorus is proper in content and uniform in distribution, anode mud is less, and an anode bag is generally cleaned generally more than half a year, so that the electroplating production efficiency is improved, and such auxiliary raw materials as theanode bags are saved.

Description

technical field [0001] The invention relates to the field of phosphor bronze ball production, in particular to an electroplated anode phosphor bronze ball and a preparation method thereof. Background technique [0002] Phosphor bronze balls are mainly used in the electroplating of double-sided boards and multi-layer boards in printed circuit boards, in addition to electroplating in hardware and other industries. The production of phosphor bronze balls usually adopts the process of horizontal continuous casting to produce phosphor bronze balls and upward drawing method to produce phosphor bronze balls. Most of the existing phosphor bronze balls for electroplating are solid phosphor bronze balls. Solid phosphor bronze balls are prone to the following problems during electroplating: 1. Copper ions can only be released from the surface of phosphor bronze balls; 2. The generated anode slime will easily cover the surface of phosphor bronze balls to prevent the release of copper io...
