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.

There is no standard. Companies select a lower control limit based on the desired cleanliness. Guidelines to consider are: * With fresh resin beds, expect get 17.5 mohm-cm water into the final rinse and then it decreases from there. * Semiconducto

Ron - no clean = no water, de-ionized or otherwise. What you should determine is if no-clean is suitable for your end product (it likely is) Certain high frequency, high reliability, low level, environmental, or other conditions might suggest a wash

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

We will be hand soldering a small number of PCBs per week (both through hole and SMT) using a water soluble flux. We will be using both standard leaded and lead free solder. The completed assemblies be hand washed in a sink using hot water. Do we

In addition to your local water departmet I would suggest that you also contact the EPA.

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
