By definition, no clean solder can be not-cleaned. The solder/flux are formulated to result in low ionic-contamination, hence, no cleaning. I have, however, always had at least one customer that requests their no-clean solder get cleaned. No-clean

We have an Ionic Contamination Testing system but short of having a monitoring record for the chemical concentration. What we have is a monthly maintenance check of the concentration and annual check and calibration of the chemicals. We seldom use th

Davef, Sorry for the late response. I was trying to gather more info. The group with low ionic contamination levels came from one of our other facilities. We want to outsource more of our product due to increasing demand. Both groups use the same

| I need an evaluation process to prove to a customer that our no-clean process does not leave excessive residue? Any ideas? Wayne, Find out your customer's concern about the residue. Residue can be a pretty ambiguous term. Is their concern activi

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

Hi Steve, Thanks. This from the trusted supplier. HASL finished PCB. Even PCB supplier is using the water wash flux for fabrication. Its almost eliminated with N2 environment. And we had got a expert view from Dr. Lee of Indium on the issue st
