we will be using water soluble solder paste. cleaning will be for smt assemblies only. waste water will be treated prior to disposal. as far as testing for cleanliness, any suggestions or recommendations on test equipment would be greatly appreciated

Do you bake the boards after 30 minute submersion? Parts and boards are netoriously hydroscopic. What do you do to combat organcis in solution? How do you know your boards are "clean"? Clean is differnet things to different people. Just currious

Hi, Guys, Can anybody tell me what kind of reflow profile is best for a no clean solder paste: Ramp-Soak-Spike or Ramp-to Spike? The paste we are using is AIM 293DX2B. Thanks a lot.

No-clean flux residues can be either cleanable or not cleanable. The not cleanable type leave a milky white residue on the solder connection after suitable soaking in water. Your flux supplier will have suggestions on the appropriate flux.

RA and RMA flux residues are "sealed" in a hard, glassy coating that do not require cleaning in many end-use environments. That being said, automotive, automotive underhood, and deep well are in that [ascending] order the three most burtal environme

Hi Ken I'm not so sure about the voltage level but I'm dealing with backplane boards. Michael, Thanks for the information, I dont mind changing the process but I need to understand why I needed to do do. That is only my concern.

Purex makes a system for air filtration of aqueous washers. I believe the only fully self contained system available. It returns all cleaning solution back to the cleaner and exhausts clean dry air back to the room. You can contact Dick Wilson at Pur
