A Localized Cleanliness Tester

and Extraction System





The C3 is unique among contamination testers - it remains the only tester on the market that indicates whether a specific, critical area of a PCB assembly is clean. You select the components and/or areas of circuitry that are most sensitive and prone to performance or reliability issues and test an area that is 0.1 in2, or even smaller. The C3 quickly provides feedback as to whether potentially detrimental manufacturing residues are present. The programmed test cycle is easily controlled through the color touchscreen display with minimal training required.


The C3 can be used right in the electronics assembly area, providing immediate process monitoring data or even incoming material cleanliness assessment. Further, the product site-specific sample extracted by the C3 can be sent to a lab for analysis to identify the contaminants and their concentrations.
