INVESTIGATING DENDRITIC GROWTH USING A LOCALIZED EXTRACTION TECHNIQUE

摘要

The corrosion site shows a very high level of WOA only on the component next to the selective solder area. Using the current production assembly as a process comparator it also shows a high level of WOA only on this location. Each area tested showed low chloride, bromide, nitrate and WOA except the area next to the selective wave.
