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
