- 摘要:
- 通过对氰化镀银溶液中主盐及配位剂消耗情况的统计分析，发现维持银离子浓度稳定对生产成本及工艺过程至关重要。通过分析找出溶液中影响银离子浓度变化的主要原因为阳极的过度溶解及零件带出造成的溶液损失。通过工艺验证，控制阳极面积、补充电解银离子和设计辅助排液工装，可做为维持镀液稳定的有效措施。
- Abstract:
- Through the statistical analysis of the consumption of the main salt and complexing agent in the cyanide silver plating solution, it is found that the stable maintenance of the silver ion concentration is crucial for the production cost and the process. The reasons that may cause the decrease of the silver ion concentration are analyzed, and the main factors affecting the changes of silver ion concentration in the solution are found to be the excessive dissolution of the anode and the loss of the solution caused by the parts being carried out. Through process validation, anode area control, electrolytic silver ion supplementation and design of auxiliary drainage tooling can be effective measures to maintain the stability of the plating solution
