摘要
化学镀铜是印制电路制作中重要工序,开发新的非甲醛体系化学镀铜工艺是当前化学镀铜领域中的热点。文章根据化学镀铜的基本原理,分析了以次亚磷酸钠为还原剂的化学镀铜工艺的特点、以及该技术的研究情况,并提出了该工艺未来的研究方向。
Electroless copper plating is an important procedure in the production of printed circuit, so to develop a new electroless copper plating technology which uses non-formaldehyde system is a hotspot in recent electroless copper plating area. Based on the basic principles of electroless copper plating, this article analyzes the technique features and the research situation of the technology using hypophosphite as reducing agent, meanwhile, the future researching direction is brought forward.
