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

Same query: Do we really need to clean the board with when using RMA ? I've been told that aqeous is not needed to clean the board, what cleaner is suitable and how?

Yes. I agree with the previous comments. If you will switch to Water Soluble Flux you need an Aqeous Cleaner.

Thanks. That's a good Idea. But question. Can a cleaning equipment (aqeous cleaner design for low standoff height parts) be able to clean my PCB given that the PCB sat in our production floor for 1 week prior to cleaning? Will the flux stick hard ont

Dreamy "Ball rolling"? Are you a bowler? My nephew does the audio for the ESPN2 production of the professional bowling tour. Search the fine SMTnet Archives for discussion on assessing cleaning machines. For instance: http://www.smtnet.com/forum

Adding a Chemistry will reduce density of solution to get under the devices more effectively. You can clean your OA flux residues well enough with just hot water and hot DI water rinse. Top batch cleaners: http://www.speedlinetech.com/electrovert/aqu

Waste Water from any cleaner must be recycled or treated before going to drain. That is the case in most states in the USA. The wash solution that is mixed with a chemistry cannot be processed thru a water recycling system, only the rinse water can.

THANKS FOR YOUR REPLY GUYS... more background... solder paste is Water Soluble. We mask the potentiometers prior to aqeous washing using solder mask, then our operator brush the solder joints with IPA after the Wash Process...I'm concerned about th

Dreamy, Adding chemistry to the wash section in a cleaner does have its advantages. It reduces the surface tension of the liquid and will remove contaminates such as fingerprints. It does however complicate the process in respect to water treatment

| | We are changing over to a No-Clean paste soon and l was wondering how other people tackle the issue of stencil and PCB cleaning in high-volume production. | | | | The paste we are using is Cobar 325RX and its pretty sticky stuff let me tell you!
