Key to Rosin Fluxes [from SUPERIOR FLUX & MFG. CO.] Type R (Rosin): Non-activated rosin flux for soldering copper. Residues are non-corrosive and non-conductive. Type RMA (Rosin Mildly Activated): Mildly activated rosin flux that contains no chlori

Hegemon, Thank you for the acknowledgment. Jacki, There are 3 rosin flux categories: R – Pure rosin (no cleaning required) RMA – Rosin mildly activated (can be used without cleaning in non critical applications) RA – Rosin highly activated (due t

In addition to Dave�s response: RO fluxes are based on natural pine (tree) rosin. RE fluxes are based on synthetic or modified rosins called resin. Below a couple of advantages resin can have compared to rosin: � Better thermal stability. � Resin

Try a rosin flux this has solved it for me on numerous occasions, no need to use heavy rosin only around 4% total solids so rosin around 1.5% is sufficient. It is down to the plasticizers which are tacky coming out of the resist. The rosin is an imme

Alcohol won't do much for the rosin residue, you'll have to scrub which isn't good on your QFP. Can you clean the assemblies before removal? A solvent such as Ensolve or Axarel would be effective on rosin.

What kind of flux is that: no-clean, water soluble, or rosin?

Sounds like a rosin flux. Is it sticky as well? Russ

True, but with rosin it should protect the joints pretty well right?

Hmm OK. Even a NASA article describes that rosin is safe not being cleaned lol.
