Thanks Karen, in the event of using an ORL0 flux combined with a ROL0 flux-cored solder, would you recommend cleaning?

Organic fluxes are made without synthetic pesticides and fertilizers. Seriously. OR fluxes contain organic acid activators. Some contain a little bit of rosin, but there is more organic acid than rosin. Some RO fluxes contain organic acid, but there is more rosin than organic acid. Different organic acids are used in fluxes; citric acid is very corrosive at ambient conditions and must be cleaned off, and adipic acid is rather benign as is often used in the most reliable low solids fluxes suitable for most no-clean assembly. The mildest ORL0 liquid fluxes are often used for touch up with ROL0 or ROL1 core-fluxed solder wire. Ask your supplier for material combination SIR and ECM data.

AM Please respond to TechNet E-Mail Forum <[log in to unmask]> ; Please respond to Julien Meyer <julien.meyer@COB HAM.COM> Hello all, I've been able to find quite a bit of information on Rosin and Resin type fluxes but not much on Organic fluxes. Can anyone tell me what Organic flux is made up of and how it may differ - particularly in the areas of board reliability - from Rosin flux? Further, I understand that it is not advisable to use two different types of fluxes in one operation as their different chemistries may be incompatible, yet we've been suggested the use of an ORL0 flux along with a ROL0 flux-cored solder. Do Organic and Rosin fluxes share any similarities?
