What do you think to use distilled water to rinsing? Irun

It depends. We've known cases where 10 mohm-cm was insufficient and others where 0.1 mohm-cm was more than sufficient. No standard exists. Our final rinse is fed from a recycling unit that produces DI water. We use 0.5 mohm-cm resistivity as the lo

There is distilled water and distilled water. It depends on the distallation process used. Using distilled water is fine, as long as it meets your standard. So, if you buy distilled water, get a written certification that conductivity is less than 1

Hi all I have a question about DI water for cleaning system. What water quality should ionic exchanger produce for assembly cleaning (SMD and THT components with BGA and microwave application). What is recommend water conduction and minimal level (0.

Not sure of what a bench top DI setup would look like. I use 3.5 Cubic foot tanks but have a special application that uses a 1 cubic foot tanks....even then its not a bench top setup. What is clean. No one can tell you. YOu can use IPC TM650 or t

New to using Ion Chromatography (IC)testing to understand cleanliness of PCB. I've been informed that one method to monitor is to use R/O/I. What is R/O/I?

Thanks for the reply. R/O/I is ROSE / Omegameter / Ionograph which is used as a baseline for Ion Chromatography.

Have used IC for years, but I'm not familiar with that, ROSE maybe. Its a stretch, but maybe R/O/I would be rosin/resin, organic, or inorganic for the type flux being used?

ROSE has the advantage in that it does have a specific acceptance criteria (J-STD-001), whereas the IC does not. ROSE allows the test to be run at ambient or at an elevated temp, IC requires the component/board/assembly to be "cooked" for 1 hour @ 8
