PCB工艺中金相分析磨抛液的研究
Study on the Detection of Metallographic Sections in the Process of PCB
摘要
Abstract
Emery is mostly used as the main component in slurry of the detection of metallographic sections polishing in currently process of PCB. In this study, we use alumina powder as the main polishing component to reduce costs. We deal alumina powder with ball-milling for 12 hours. Then the slurry is made up of 3 % of alumina powder, 0. 1% of activated carbon powder, 0. 5 % of gallic acid and about 96% of ethanol. It can meet the requirements of stability and polishing with decreasing cost.关键词
