Method of Detecting Contamination
Minimizing contamination on a printed wiring board (PWB) is crucial to an assembly’s performance and reliability. There are two classes of contaminants, ionic and non-ionic, that can be deposited during electronics manufacturing processes. The type of problem experienced by the customer determines the type of contaminant expected, which in turn determines the test method employed. Non-ionic contaminants are typically organic compounds, such as polymers, oils, or greases that are left on a printed circuit board (PCB) after production. An organic surface residue can cause problems with conformal coatings or may be an indication of an issue with the solder mask. Ionic contaminants can lead to corrosion and dendrite formation, both of which can cause electrical failures.
