Water Cleaning PCBs

Electronics Forum | Thu May 30 10:06:20 EDT 2013 | rgduval

In general, it would not be advisable. DI water is used for a couple of reasons. First, the missing ions aid in the cleaning process, as they seek to bond with the material on the board, allowing the water to act like a fairly aggressive solvent.
