The C3 performs real-time cleanliness analysis, the company said. It operates using a steaming technique to extract residues from a specified area and electrically test for conductivity and corrosivity. Results are returned in minutes, Foresite said.

The process is a means for localized residue assessment and for collecting samples for ion chromatography analysis. The C3 tests specific areas and pinpoints the location of residue without exposing the entire board to water, which can dilute test results.

Tests can be localized to an area of 0.1 in², Foresite said.
