no-clean flux vs. impedance

Electronics Forum | Tue Feb 19 09:26:54 EST 2008 | jdengler

The low solids flux that is commonly called no-clean can affect some circuits. We are building a PCB that measures pico amps. The customer required that it be cleaned. We would rather used the low solids and eliminate a step. The customer had

Amtech 4300 no-clean+washable flux

Electronics Forum | Sun Dec 11 22:39:36 EST 2016 | ppcbs

We have been using the Amtech line for over 12 years now with all of our PCB and BGA Rework. The NWS-4400 is mildly active and will give better results with Lead Free Solder. Note that the LF-4300 is considered a No-Clean. However it will show lea

Beaker Scale Testing for flux cleaning chemistries/surfactant

Quick question, how are you measuring the effectiveness of the cleaning process to remove the flux?

Beaker Scale Testing for flux cleaning chemistries/surfactant

Electronics Forum | Sat Apr 23 00:21:10 EDT 2011 | azrina

As am doing screening right now, am not measuring the total cleanliness yet, i just observe by taking photos (FYI, am varying speed for conveyor belt for cleaning) and see whether the flux is able to be removed by certain parameters. the speed am usi

SMT Solder paste and wave flux evaluation

Electronics Forum | Fri Jan 28 12:18:32 EST 2005 | Chunks

Your best bet is to do a decision making matrix. Each company has so many different criteria�s it's hard to pick out which one might be important to yours. Simply pick out your top 5 paste manufactures. Next decide what your "Eliminators" are - th

ROSE testing for no-clean flux soldering assemblies

Electronics Forum | Mon Aug 19 13:32:54 EDT 2019 | aqueous

ROSE testing a post-reflow assembly which has been reflowed using no-clean flux may not yield information that is helpful. No-clean flux technology works by encapsulating the flux's activators and other chemical constitutes that would be harmful if l

how to prenvent flux risidue in the blind vias.

Electronics Forum | Mon Feb 19 22:56:20 EST 2007 | davef

Russ We agree with your comments on plugging from one side only. But... We believe that it IS possible to trap process chemicals [technically, not flux] in a blind [or any other] via. This can be done by plating the via closed, rather than pluggi

Re: Where can I purchase a PCB with a bare copper grid for solder flux evaluations.

Spray Fluxer Titration Kit

In a Nut Shell.... Titration is used to maintain the Concentration level (Solids Content) of a liquid flux. Keeping the concentration level constent ensures repeatable fluxer & soldering performance. Specific gravity measurements can be used to do t

I'd have to disagree with the Electrovert applications guy. I'd recommend SLOWING down the conveyor between .5 to 1 FPM - effectively, you're REDUCING contact length (because contact length = dwell time * conveyor speed), hence getting better peel-o
