Water-soluble flux vs test socket cleaners?

Mar 12, 2015 | Hello. I would like to know the difference (if any) between water soluble flux and test socket cleaners (e.g. for Burn-In Board test sockets). As far as I know, they both remove oxides (tin & copper) with an activator, solvent and surfactants. Thank you!

Apr 22, 2011 | Quick question, how are you measuring the effectiveness of the cleaning process to remove the flux?

Beaker Scale Testing for flux cleaning chemistries/surfactant

Apr 22, 2011 | Beaker Scale Testing for flux cleaning chemistries/surfactant Hi, I am doing my master degree in flux cleaning process for flip chip assemblies and required to establish a new receipt for flux cleaning. currently, i am doing screening process for the parameters involve ; temp,pressure, surfactants, speed and angle of penetration using inline cleaning machine

Conformal coating

Dec 10, 2010 | Causes of dewetting in conformal coating. Factors that influence dewetting usually involve non-ionic contamination such as: * Residues from board manufacture including silicone surfactants from solder resist & HASL rinse contamination * Component residues like mold release agents * Silicone oil

Conformal Coat over No-Clean

Jun 30, 2010 | Tim, try and incorporate an inline wash system. We use one with a surfactant and it cleans the "NO CLEAN" fluxes well. If you dont have an inline system, you can manual clean the boards with an surfactant and IPA. You can also do an ionic contamination test to ensure the cleanliness of the board

Help with dewetting

May 25, 2010 | Where on the assembly is the dewetting occurring? Factors that influence dewetting usually involve non-ionic contamination such as: * Residues from board manufacture including silicone surfactants from solder resist & HASL rinse contamination * Component residues like mold release agents

Motherboard become NO POST when humidity increase to 90%

Nov 24, 2009 | I agree Patrick many people blame the assembly fluxes when it is some other hygroscopic chemistry left on the bare PCB such as surfactents from the HASL process these will do exactly what the guy reported in his post fail then cool down and pass everytime. If it is this type of chemistry

Hand Sanitizer

Sep 14, 2009 | Glycols, polyglycols, polyglycol surfactants, polyethers, and glycerine are used in water-soluble flux formulations because they provide excellent wetting of the board surface and dissolve the more active materials used in these formulations.

Coils and Water Soluble Fluxes

Oct 10, 2007 | .), Coilcraft does not perform tests using cleaning systems. Water based solvents may include neutralizers, surfactants, saponifiers, dispersants and anti-foaming agents, so Coilcraft cannot recommend a solvent (other than pure water and/or alcohol). Coilcraft cautions against the use of water

Dross Eliminator

Aug 8, 2006 | 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 guess that's why they call it a surfactant

Stencil cleaners.

Jul 17, 2006 | through micron filters. Lead ions will also be found in the wash solution of an ultrasonic machine. The key element to determine if two separate machines are required is the rinsing ability of the chemistry. Surfactants (detergents) tend to rinse easily and thoroughly. Saponifiers and solvent

May 27, 2006 | black. This will allow you to fine tune your spray pattern to get the most even flux deposition and may allow you to reduce the volume you use and make your customer happy. Most fluxes are loaded with surfactants that allow them to wet nearly any surface, if the flux is applied in proper volume

Selective solder nozzels

May 3, 2006 | "and dip it in your solder bath for 10-20 seconds." Do you pre-tin them first or just dip them in regular solder? "You can't talk to molten solder, but surfactant will listen." "Remember, we're all in this together."

If it is a detergent (surfactant) it will remove the wet epoxy as a wetting agent (form a film between the wet epoxy and the stencil) and likely not attack the cured stencil epoxy. Another cause of delamination (other than

No solder and solder bridge after Wave solder machine

Nov 17, 2005 | change - try to use a newer chemistry with better activators, like Carboxylic acid, and fluxes with more surfactants content. If your budget permits, switch to spray fluxing as well to get a better and more controlled flux deposition and eliminate the need for titration and specific gravity checks

Same wave process do not apply to all finish board

Oct 18, 2005 | I suspect the problem is a surfactant issue in your flux. I have seen where boards are fluxed, hit the solder fountain and come out like they never touched the solder. There was an inadequate surfactant between the solder and the PCB. I know you don't want to hear this but not all fluxes work
