Hi, I know this is a total screwed-up. Operator used the wrong paste. It was supposed to be a clean paste but she was issued with no clean paste. What happen was when the brd processed thru', after the reflow, the girl passed the boards thru' DI wa

We need to use water-soluble paste due to cleanliness requirements. No-clean does not mean No-contamination. I have talked to a lot of people who use no-clean and they still wash their boards except now they have to use chemicals to do it. So, you

I've never heard of steaming a board either. You said that steaming cleans it better after the wash process. What is the steaming process cleaning that the washer isn't, flux residue, solder balls, or what? Also, try and identify the main difference

I think you can effectively clean under any other low standoff device. It's an issue of surface tension, pressure, and flow rate. DI water is the starting point, but the surface tension of straight DI water makes it difficult to get under low stand

Hello We are using a No-Clean process for a lot of boards that we do, but the customer needs the flux removed off the bottom side of the board and there is to many leaded components that can not go through a water wash, so is what we do is clean th

Now the ball starts rolling. I'm lookin' for a new aqeous cleaner. Do I really need chemical cleaners or saponifiers, surfactant etc. for an Aqeous Cleaning Machine in removing OA or Water Soluble flux from under my 1.27mm Pitch BGA down to 1mm Pitch

WA Engineer, Good Morning, Your cleaning system requirements will depend on your chemistry use in production. Are you using RMA or OA flux? This will impact the requirements of the cleaning system. OA will allow you to use a DI water cleaner. If you

Most metal stencils today are cleaned with a water based cleaning solution. 3 choices are most typical: (1) Water only for water-soluble paste (2) Water + Organic for rosin and no-clean (low residues. This affords lower temperatures and is easier t

We wand to start using of water-washing-off pastes and fluxes. In the technology of cleaning supersonic cleaning + deionized water at finish will be applied. Hence there are some questions: 1. Is it enough to use only water while cleaning or i

The most effective cleaning of high solids RMA has been with a good saponifier (5-7%) [eg, Kyzen Aquanox, Lonox formulations, Envirosense Envirogold, etc ] in deionized water, 150F, with 2-3 DI water rinses. Dull solder connections when you do spot
