Ionic contamination test systems measure extractable ionic residues on circuit boards and other suitable electronic samples. Such residues can originate from flux, handling or cleaning processes and may contribute to electrical leakage or corrosion under unfavorable conditions.
The test typically evaluates an extraction solution rather than measuring every location on the board directly. Results therefore depend on sample preparation, extraction conditions and the measurement method. A bulk contamination result is useful for process monitoring, but it does not identify all contaminants or locate a specific residue.
For repeatable testing, consider the sample dimensions, instrument range and control of the extraction process. Calibration, baseline checks and consistent handling help make comparisons meaningful. Acceptance criteria should reflect the relevant product and process requirements. Where a result raises concerns, further analysis may be needed to understand the contamination source.
