Go Greener in Your Cleaner! - Cleaning Process BenchmarkingPresenter: Dr. Harald Wack
Date Published: 5/2/2010
This study was prepared to focus on cleaning process benchmarking. In other words, how can one compare established cleaning processes with newer process technologies? The authors will present recent cleaning challenges including the removal of flux residues under challenging low standoff components such as 0603 chip capacitors, while using pH-neutral de-fluxing agents as well as alkaline chemistries with reduced VOC levels. The objective was to assess their effectiveness, demonstrate any limitations while adhering to higher environmental standards. To further demonstrate the challenge of increasing VOC limitations, the study also highlights experimental findings on vapor recovery methods used presently in the industry. This will allow users to benefit from experimental comparison data to further enhance their respective cleaning process while conforming to the latest environmental regulations.
