Hi Dean, We are a manufacturer of cleaning equipment. I'm not sure if your machine is one of ours or another brand. Regardless, I am happy to provide assistance. In order to maximize the level of "helpfulness", it would be helpful for me to know mor

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

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

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

We are currently in a Clean solder process (SMT+Wave Solder+Washing). Now our management is planning to convert to a No-Clean process in SMT due to limitations of solder availability and reduction of washing process. Question1: Is it possible to was

Your fluxes are required to be compatible per J-STD-001. I wouldn't even attempt mixing no-clean (rosin) and clean (assuming water soluble) fluxes on the same assembly, especially if the fluxes are from two different vendors. If your paste and liquid

definitely don't mix clean and No clean. Run No Clean as you decided, but have your flux and paste manufacturers advice, how this flux can be cleaned(if you decide or required to clean). I know for a fact that some of these NC flux residues are almos

We recently got a batch wash machine that can use a chemical cleaner. (not a saponifier). NOW I feel confident cleaning no clean boards. Without a machine that can heat water and use a proper cleaning agent, I would not trust cleaning no clean boards

Hello Mark, I wish it were that simple so I could direct you to a particular manufacturer and stencil cleaner model. Unfortunately, there are several issues complicating the process of cleaning all these applications in one machine. First and fore

Hi, Yes, I would hate to resort to cleaning, but the product must be clean. We have been using palettes to keep most of the flux off the PCB, but there is still residue around the connectors. Does anyone suggest a good no clean flux to use with le
