Hi Dale, I have copies of the articles of which Mike references. If you need copies for support, contact me at: bill@smartsonic.com. Rinsing should be done by ultrasonics also. Spray in atmosphere systems will not penetrate into the same tight ar

I use a water soluble flux to solder an LCD into gold plated through holes of a .031 circuit card. Problem is the current water soluble flux (850-33) is not made anymore (the drop in replacement has a different formuala and does not work). The main i

I tried MS2 for almost two weeks and I can see it works. MS2 is more a preventive tool rather than a solution to convert pour on top of the dross. Very important if you use this stuff is that you do the encapsulation of the wave, the bigger the surfa

It works. It is a process chemical that works for leaded and lead free solders (two different products) take a look at the website http://www.pkaymetal.com and look at the MS2 Molten Solder Surfactant sub page. The reliability data is there. It has b

Hello all, just wanted to say that I've been using MS2 for 2 months now. Yes, it does eliminate dross. Yes, it is a little messy. However, we've seen a significant drop in our DPMO's on both leaded and lead free process. The solder is so much cleaner

I agree with all of the previous comments. 1) Here are a few things to keep in mind when cleaning with water. To effectively clean, any liquid must wet the surface. By itself, water has a surface tension of 70 dynes/square cm. This is relaively hig

Not intending to undercut Mike's offer, but to compliment it. Consider asking Heraeus for guidance about cleaning the residues from reflowing your paste. Some NC flux res: * Cannot be cleaned. * Can be cleaned after a relatively short period of tim
