印刷线路板含铜废蚀刻液的回用处理(一)

摘要

This article is to be published in two parts. In the first part, the production process of printed circuit board (PCB) and the features of various etching solutions were introduced. The factors affecting the etching rate of acid cupric chloride etching bath and its maintenance were summarized. The performance and operation conditions of acid and alkaline cupric chloride etching solutions were compared.%本文分两部分刊出.第一部分介绍了印刷线路板的生产工艺,以及各种蚀刻液的特点.概述了影响酸性氯化铜蚀刻液蚀刻速率的因素及其槽液维护,比较了酸性与碱性氯化铜蚀刻液的性能及操作条件.
