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.

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

MK, In most cases, if the machine is completely closed-looped (prewash, wash, prerinse, rinse, final rinse etc), then the water should not require changing. As with most inline cleaners, there should be a considerable amount of water loss in the cl

Rob If your supplier replaces your carbon bed when the ion beds require replacement [when you call after the light goes red], it will not hurt anything, except increase your costs.

Hi Jacob, NC vs WS, what a story! No-clean paste means no-clean for your products but what a mess it makes in your reflow systems. If you are a contract maunufacturer of high volume production, then No-Clean is they way to go. This helps keep your co

There is no standard, nor should there be. You need to establish a standard that meets your customer requirements. The problem with those old-timey standard is that there's just so many choices. What works for you just might be too strict [or loose]

Dave, To tell you the truth, I couldn't tell you. I came into this company with the system installed. When the resistivity is depleted, I call Culligan. It may only be an in-line cartridge filter that they change. We've noted a change in water q

steve- once again I mention that the lead that is actually in the water is in solution i.e. the lead is in a molecular form that has attached to a H2O molecule. To have a minimum of lead that is below the regulated ppm, there cannot be any chunks,
