Been rootin' through my card file. Other sources I'm aware of, but can not substantially comment on are: * DI water generators: Unit design 714.282.8100 fax8188 * Remco Engineering: modular ion exchange systems * Advanced Separation Technologies: co

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

If you�re running chemistry in the wash, the wash temperature will be influenced by the chemical manufacturer�s recommendations. Typically, wash chemistries recommend operating temperatures between 130F and 150F. If your application is straight D

My understanding is the resin does a one to one ion exchange. And that when it becomes saturated, it does nothing. edit, and you do mean tap water, not toilet water, right?

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

Our DI system has a carbon cylinder and a mixed bed cylinder. This is from the Mfgr website: "The Technical Devices' Nu/Clean Recirculating Water Deionizing System is engineered to remove all organics, chemicals, and heavy metals via particle

Edmund: Responding to your questions: 1 What is purpose of using DI water to wash a PCBA? Compared to tap water, DI water is less likely to leave: � Metal cations on sensitive components. � Salts of Ca, Mg, and other stuff on metals on the assemb

It would help to run a carbon, anion, cation, mixed-bed configuration with pure DI as the final rinse. IF your incomming water is really bad you can run a RO unit to "prepare" the water for ion exchange. Do you run omega meter or ionograph testing

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.
