Q1 Can anyone explain to me what is the clean and non clean solder? A1 The trend away from CFCs has lead many users to evaluate switching to no-clean soldering processes. The term "no-clean" is actually a common misnomer when used to describe a flux

The design engineers I work with are blaming some circuit problems on what they think might be related to the no-clean flux residue. (It couldn't be the design.) Has any body else seen noise issues in high speed circuits related to no-clean flux resi

We have RF boards with ... * No solder mask * Strategically placed globs of solder It's possible that your boards will not work with NC flux res on them. We generally don't see noise problems. We loose one of the edges [front I think, but don't

Deja vu! When I read your response I turned around to see if you standing behind me listening to our problem. We currently make about 50 different boards all using no-clean that have no problems, yet this newest boards has a couple of issues that eng

Hey!!! Watch it!!! I don�t want to get you believing too much of this stuff. But if you bought that, listen to this � some circuits are so critical with that skin effect stuff that they use silver as the top level solderability preservative. Turn

Interesting...the very reason we use water soluble paste on some of our boards is for that reason, although I've never been able to get anyone to show me something in print that supports it. It's just what engineering has told me. We currently have

To all, This may appear to be laziness on my part, but I need to ask for some advice. We are in the process of qualifying no-clean solder paste to replace or current RMA paste. I have performed qualification runs and extensive reliability testing

OK, lemme take a different angle on this, �cuz I forgot to touch on this when I first responded. I mentioned a study ["Evaluation of Low Residue Soldering for Military and Commercial Applications: A Report from the Low-Residue Soldering Task Force"

in a thread titled ".5mm bga" there is a reference to a paste by alpha that is no-clean and is supposed to be made specifically for this situation. I suppose that increasing the pad dimension to .012" is out of the question? Russ

Rejuvenated solder paste

I have done this several times in order to save my butt: adding liquid flux in a jar of not so fresh paste, stirring it slow for 2-3 minutes, to make it usable. Of course, use no-clean flux for no clean paste, etc. During one production slow-down,
