Hi All, Let me summarize the key facts and findings: 1) This is not a permanent problem. Only one production batch was affected. The cleaning solution was exchanged and now the cleaning process runs normally. 2) Probably the residues are not ion

Hi All, As a result of equipment damage I have a problem with a cleanliness of printed circuit assemblies. One whole production batch was polluted by ionic residues because a large amount of hard water had been penetrated in the water-supply system

We are using a water wash paste for our boards which is leaving ionic contamination ( salts). In the presence of low humidity levels this creates the effect of a capacitor. Our product which is test instrumentation does not calibrate. I am lookin
