ZERO ION G3-500A Ionic Contamination/Cleanliness Tester

Quick Overview

ZERO ION G3-500A is our third generation IPC J-STD approved resistivity of solvent extract (ROSE) tester. Today's Zero Ion is more feature rich and operator friendly than ever before and the dynamic measurement technology continues to provide accurate and highly sensitive cleanliness measurement results essential for modern high reliability manufacturing environments.

Dynamic Rose Testing

Dynamic Rose Testing

●   ZERO ION is an industry standard for resistivity of solvent extract testing. The dynamic measurement technology provides sensitive and precise cleanliness data in compliance with WS 6536, IPC J-STD 001 TM 650 and other current specifications.

●   The dynamic method was found to be the most sensitive ionic contamination test by the EMPF/US Navy MIL2000A. The spray under immersion and continuous filtration design allow for repeatable and accurate process monitoring results.


Reliability Matters

Reliability Matters

●   During a test the ZERO ION will automatically regenerate the test solution to 150 meg-ohms of resistance and then prompt an operator to insert an assembly. Testing will then automatically begin and continue until the solution again reaches 150 meg-ohms. This continuous filtration, while spraying the assemblies under immersion, allows for optimal removal and measurement of ionic process residues, expressed as ug/in2 / ug/cm2.


Process Controls

Process Controls

●   The control platform developed for ZERO ION combines a simplistic operator experience with a versatile and robust program. Features include barcode scanning, an SQL database server, aSPC recording, password protected recipes, contamination reports and graphs, data networking and virtually unlimited recipe storage.
