前言最近有大量的文章介绍Sn-Pd 敏化系统的化学处理过程。这是因为该敏化系统对印制板的制造和塑料表面镀都是重要的。Sn-Pd 系统(通称“一步”法)比老的锡和钯分开处理的方法有很大的优点,因此在工业应用中看来正在取代老的处理工艺。尽管Sn-Pd 系统得到了广泛的使用,但其化学处理过程仍有很多问题解释不清。此文只讨论清洗、加速处理以及在沉铜开始的时候所发生的化学变化。在详细地了解这 Preface A large number of recent articles describe the chemical treatment of Sn-Pd sensitization systems. This is because the sensitization system is important for the manufacture of printed boards and plastic surface plating. The Sn-Pd system (commonly referred to as the “one-shot” process) offers significant advantages over older tin and palladium processes and therefore appears to be replacing the older processes in industrial applications. Despite the widespread use of Sn-Pd systems, there are still many problems with chemical processing that are not clearly explained. This article deals only with cleaning, accelerated processing, and the chemical changes that take place at the beginning of copper sinking. Learn in detail about this
