The latest installment in Aqueous Technologies' E-Learning video series covers the newest cleanliness testing system, the Zero-Ion G3.�The E-Learning video presentation covers all aspects of ionic contamination (ROSE) testing including detailed coverage of why cleanliness testing is more critical today than ever before, �industry approved cleanliness testing alternatives, industry-assigned equivalency values, theory of operation, and features and benefits of cleanliness testing.

�An Introduction to the Zero-Ion G3 Ionic Contamination Tester� can be viewed on Aqueous Technologies' Web site, http://www.aqueoustech.com or at http://www.aqueoustech.com/ATU.html.
The Zero-Ion has been in constant production since the 1980s.�Thousands of customers rely on the Zero-Ion to determine the final cleanliness of post-reflow circuit assemblies as well as bare boards. The Zero-Ion G3 is the newest, most advanced Zero-Ion ever designed.
Modern cleanliness testing frequently requires the testing of assemblies reflowed with no-clean solder paste.�Unlike other less sensitive static-based systems, the Zero-Ion G3 cleanliness tester uses a dynamic measurement technology, the method of choice for detecting (weak) ion activators commonly found in no-clean fluxes.�With dynamic measurement technology, the contaminated test solution is monitored and then filtered to supply de-ionized test solution back to the test chamber, resulting in greater solubility/sensitivity.�The increased solubility eliminates the �saturation limit effect� associated with other static measurement methods.
