Think You Don't Need to Worry About PCB Cleanliness? We Do!

Testing for circuit board cleanliness using ion chromatography (IC) was once the domain of high reliability applications. The continued miniaturization of today's electronic products; including the fine pitch and low standoff (and QFN is the worst of both), has made this type of testing increasingly mainstream. This white paper details the process of IC and provides the reader a clear understanding of best-in-class pass/fail criteria for ionic contaminants.
