Question: What is the standard for de-ionized water in smt field if any at all. Would it be more cost effect to buy an de-ionizer then to buy the water? If so can you point me in the right direction. Thank-You

De ionized is de-ionized. Contact your local water supplier such as culligan or whoever. They can give you the rundown on leasing or buying tanks, etc... Your cleaner will have to have some type of provision for adding external filtration/deioniza

Hi WRIGHT, When you the standard, I assume you are talking about what kind of set-ups. If so, then RDR is right. Contact a supplier. Most sell the water and also units that can make D.I. water. It depends on your need and size of your cleaner.

Is there any harm in washing SMT soldered with NoClean paste? The PCA has some large thru-hole connectors that we would prefer to do as water soluble on out selective solder but the SMT consists of LGA's and other low parts that we would not be able

Davef is right on as usual. We are doing exactly what you do. Some smt with no clean paste then the plate through connectors on our selective solder machine using water soluble flux. We then clean with a ultrasonic water process. We do see the re
