We've been using a newly installed DI re-circulating system. It's been a big headache. Mostly understanding what causes our resistivity to be unpredictable. I think I've got a handle on that part now. The system consists of a Carbon,HMR(chealet),Cati

We dump our water. We only run the wash machine a total of three hours a day so there's not a ton of waste there. Our cation, annion, and mixed-bed tanks are leased. Consequently, they must be sent back for what the vendors call "regeneration," whe

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
