The issue is not the cleanliness of your in-bound water. The issue is the cleanliness of the board your customer receives. Look at J-STD-001C, Para 8, "Cleanliness Requirements". The end product cleanliness is the end result of your: * In-bound

WA Engineer, If you are able to change over to OA instead of RMA, you can clean effectively with DI water. (I know that some Military contracts specify RMA) Most systems are designed to filter the waste water of ionized contaminants before dumping t

We use WSM-90 which is a red water wash off solder mask from Contronic Devices, Huntington Beach, CA, 714-897-2266. We bake the bare board at 150 F for 30 minutes after applying the mask. We run 130 to 140 F DI water in the inline cleaner which rem

Graham: I agree. Very thorny. What is clean?? And how is that controlled?? Back 25 or so years ago, soldering was done with high solids rosin fluxes. The issue with cleanliness was ionic contamination. The US military and others set a fairly a

We are anticipating switching from RMA to OA flux for both reflow and wavesolder in the next few months. If you use a batch cleaner running DI water only I would like to hear your experiences. How is it for cleaning under low standoff components li

| I have a layer of electroplated solder (10/90) that appeares to have some sort of contaminent on it. Water will not wet to the layer in some areas. I have tried using 10% HCl in DI as a cleaner as well as 7.5% Fluoboric acid in DI. Neither has t

:Steve, If you want to get a constant flow of higher quality water to supply to your cleaner, you could install a fliter, carbon filter, softener, and an Reverse Osmosis unit that dumps to a storage tank and draw from that. This will give you a const

Look for the following machines: Aqueous Technologies ECD EMC Austin American The above mfrs. make "industrial" grade dishwashers for assembled PCB de-fluxing. Search any of those names followed by "..... batch cleaner", and your search engine will

With most folks using closed loop DI beds on their cleaners, water soluble masks have fallen out of favor. Tends to gum up the works.

Hi all I have a question about DI water for cleaning system. What water quality should ionic exchanger produce for assembly cleaning (SMD and THT components with BGA and microwave application). What is recommend water conduction and minimal level (0.
