We currently use Vigon SC-202 in our spray in air system. SC-202 has 830g/l VOC content, so I don't know if that will help reduce your VOC's or not. We used Smart Sonic 440-R in ultrasonic application with great results, but we haven't tried it in

I know it is not what you want to hear, but first and foremost, you must consult your local regulating agencies and here is why: Solder paste contains heavy metals. We are all familiar with the problems associated with lead, but lead free solder pas

Hi, Does anyone have any experience of cleaning lead free solder paste residues off pcbs in a vapour degreasing process using Ensolv Ionic ? Any guide as to the best cleaning cycle would be appreciated. thanks

We've started off with Kester 951 'no-clean' so far which is alcohol based I believe. It seems to do very well with foaming, activation and low residue, but if we can move to water based and get good results that would be great. The 951 flux and thin

Dave is correct. No-clean flux + water = white residue (unless the proper chemical is mixed with the water). Additionally, no-clean flux + IPA = white residue. Many saponifiers work well as do other cleaning agents. White residue may also be a re

White residues are a common problem when cleaning no-clean fluxe residues. The white residue forms when the flux residue is partialy removed, etc. Alcohol should not be your only solution for cleaning. In general, solvents may attack some plastic par

We use a small DI water generator feeding a diaphram type pressure tank going to a standard dishwasher. We have some filters in-line also to prevent white residue on no-clean boards. I cant think of a good reason to buy a $5,000 board cleaner rather

Dear Rick , thanks for your reply. It is very helpful. I'll get chance to try the Ensolv in a lab next week to see if we can remove the paste residues. Thanks again

Hi Graham, I've worked in the industry selling EnSolv, Lenium, and now ENTRON solvents, which are all based on stabilized NPB. These solvents do not always clean the no lead pastes. The problem is that the pastes are becoming more like adhesives,
