We've configured SMT and Wave lines such that each line can run either No-Clean and Water soluble process. As we are doing cleanliness study, an observation is there may be cross contamination when we share the Rework benches or PCB trays between No-Clean and Water soluble. Hypothesis is trays or benches may transfer active ionic elements possibly from water soluble boards and contaminate No-clean assemblies. Do you have any experience or knowledge of such concerns?
