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

| 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),

We use a inline water wash system to clean our PWA's. How low should i be able to let my DI water resistivity get before replacing the DI tanks. Is there a standard i can get on this subject. Thanks JL

I know it is not what you want to hear, but first and foremost, you must consult your local regulating agencies and here is why: Solder paste contains heavy metals. We are all familiar with the problems associated with lead, but lead free solder pas

Ahhhh, Dave, I'm glad I can still count on you for some real cutting edge info. yuck, yuck. Believe me, there's a lot more information available on how to resolve no-clean issues than there is on how to keep this stupid board wash/DI/Stencil wash/

At my last place of employment, that was the big reason why nobody (especially the Design Engineers) bought into a no-clean process - interference with high-impedance circuits. One guy was so paranoid about flux residues remaining on the board, that

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
