Hi Rob, I must take issue with your statement �By definition, no clean solder can be not-cleaned�. All no-clean fluxes can be cleaned. Whether or not one cleans no-clean depends on a variety of factors. More than eighty percent of all post reflow

Comments are: * Sounds like it's necessary to clean "heareous F381, F352 no clean solder paste" in your application. Consider a paste that may be better suited to your application. * If you're cleaning "low residue flux", consider using an organic ac

The propensity for flux residues to cause shorts can be increased in humid environments where water molecules hydrate the surfaces. At high frequencies, electrons travel on the surface of conductors/insulators, increasing the likelihood of shorts in

Hi all How can I find the technical paper or source of information about using No-clean flux with high frequency apllication. High frequency mean more than 2 GHz - 5 GHz. I heard from my colleague that No-clean flux residue on board effect to high

Grant, No-Clean paste + IPA = White Residue! #1: Stop using IPA #2: Switch to either a solvent-based de-fluxing chemical or an aqueous-based de-fluxing chemical. If you are using an ultrasonic cleaner for your boards as stated, do not use sapon

Bruno The real question about your troop using Kester 951 wave solder flux on boards is: how is the flux applied and controlled. See, when you apply this flux with your wave solder fluxer, it is ideally applied in a metered fashion with your fluxer

This is one of the most common questions I get asked. Why clean no-clean flux. It was stated earlier that no-clean residues are benign. This may or may not be accurate. It depends on several factors including the reflow process. In a perfect world, t

Sorry to disappoint. No-Clean fluxes are resin-based. They are not soluble in water. Water soluble fluxes are by nature Organic Acid and are soluble in water AND must be cleaned within a short period after reflow as they remain conductive and corrosi

Thanks for the kind words Dave. At no point in my reply was I trying to sell anything. I apologize to anyone who believes otherwise. I agree with the poster, if assemblies are going to be cleaned, consider a flux designed to be cleaned. While this is
