Various processes throughout the factory will use a stamp to signify ICT has been completed or QA has been done. The problem we are having is once the boards have made it through all the steps and have the stamps on them signifying who did what; the

You need to switch to an alcohol based stamp. It will work cause that's what we use.

We had a similar problem with foam in our inline cleaner (TD). The problem were the solder paste flux residues. Boards went straight from SMT to Wave process and then washed. Anyway we changed the solder paste and problem solved. Are you using saponi

Dave is absolutely right! A question is there free standing DI water left on Parts after wash and rinse, if so this can definetly exacerbate the problem. You can try to remove excess DI water by using an IONIZER air source to blow off any water. S

Ashok, It is most likely not the DI water that is attacking the aluminum rather it is the saponifier. DI water is only in contact with the parts for a relatively short time. If your cleaning process provides for a rapid drying cycle, you should be

You have a lot to think about! What does the flux manufacturer recommend as far as specifics like water temp or pressure? Do they recommend high temp di-water a detergent or saponifier? Do you currently have a cleaning machine, batch cleaner or inl

That's a good idea...and to add on to it, you could wash after the wave, too--it really doesn't matter. A question about this though--unless your Customer specifically requires "clean", no-clean flux whether it's ugly or not, is permitted by IPC,

| You may want to rethink using an inline for both OA and No-Clean applications. Since the majority of your applications are OA, it would not make a lot of economic sense to run saponifier in your inline for a minority application. My suggestion is

| We're a CM doing low volume/high mix and are considering buying from one of the two big names, TR** or Sp*******/El*********. We need saponified wash for some of our no-clean over wave; the great majority is OA from our SMT lines. Any thoughts? |
