Cyanide Copper Plating Reinvents Itself: Understanding the influence of bath parameters help achieve the most from a copper cyanide bath

摘要

One of the outstanding properties of cyanide copper baths is excellent throwing power (TP) or metal distribution ratio, especially when compared to the acid sulfate systems. As most plating thickness specifications on parts usually do not apply to the high CD area, but to the average CD region, or more often, to a low CD area, improving the metal distribution ratio may be the best route to increasing average metal thickness.
