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.

Need some input here..... The fear is that the if we use water soluble flux at the repair operation, that the no-clean encapsulation will capture some of the organic material as it cools down and goes to its original state. The organic material wil

We have passed testing using this process, I would consider it on a case by case basis however. We are very careful about the quantity of the O.A. that we use. The water soluble flux is gone after cleaning unless it was/could be encapsulated or tra

You do want to be very careful with potentially entrapped organic materials as they are prone to causing electrical leakage failures particularly around sensitive devices. There is a new clenliness testing tool available that tests a localized area

Does anyone know of an inexpensive way of holding small parts or boards in place in a wash basket to prevent them from moving during cleaning process.Keep in mind you want the top of the parts/boards to also get clean. Thanks

We did some tests with good result. No failure physically and functionally. Is there report/study/documents about this procedure so we can convince customer to approve our process using ultrasonic wash. Thank you, Dave

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

I relate to your problem. We face this issue sometimes. It's mostly flux from SMT, TH process or rework boards. To avoid foam in our Washer, we soak the boards in hot water for 10-15 min before running it through the washer. Or you can spray the boar
