Density is an "implied" measurement to determine activity. Most flux suppliers can sell you a flux acidity (activity) measurement kit. I used one from Multicore a few years back. We used it once in the morning and once after lunch to monitor no-clean

If your pots are open you then just need to dry them. Don't hide them. Are they rated for water clean? If not hand solder after cleaning with no-clean wire. Hand cleaning with IPA is dangerous - you really just push the flux around and don't was

With recent implementation of VOC-Free flux in our shop, we've experienced little solder fines/balls on the above combo of VOC-Free, Water Based, and glossy to semi-glossy mask finish on PCB's. The solder balls show up on close conductor spacings, ~

Blimey just seen the picture that is bad. You could try to dissolve some of the residue/gunge in IPA if it is flux residue it should readily dissolve if it is resist issue then only portions will dissolve leaving a white powder which is Talc If you

First, we assume the white residue is only on the connector and not on other components. That would imply that either: * White stuff was on the connector when it came in-house from your supplier. [Confirm this theory by baking some connectors from

Degeaser isn't a good chemical to use either cause it leaves a residue so don't use it. alcohol works good. Not sure why everyone thinks it blows up. heck i remeber back in the day when I hade 24 inch foam fluxers bubbling flux and alcohol (IPA no

Halo; In your last message you did not mentioned why your customer need to use IPA to clean PCB's as their requirement and what subtances they want to get rid of (is it flux stain PCB's or component?).If so recommend your value customer of flux 910

Hi John, Are you talking about cleaning the pallets after running to store them? or during production? well in any case...I recently started to use this cleaning solution "Cybersolv" from Kyzen. It is water soluble and also can be used instead of IP

But soon after cleaning and drying with IPA, we find a white residue formation. A: IPA will not nothing to clean your board. The white residue is exactly what you should expect. Search the fine SMTnet Archives for background. >How do we avoid th

Hi, just my comment, theoretically No Clean means no Ion Contaminants from Flux, but it some some case ion contamination (Cl-Br-F) could come out from raw PCBs, from Components, from fingerprints, etc. To incorporate a ROSE step in the pro
