J-STD-001C, 7.2.1 Flux Application says words to the effect of: When an external flux is used in conjunction with flux cored solders, the fluxes shall be compatible. Regardless of whether these are or not flux cored solders, this begs the question:

Hi all Pls. help advise. Our board use RMA solder paste (Pb-free Sn96.5/Ag3.0/Cu0.5). Can we use No-clean paste flux (Delta 670S1) in rework process? If it can not be used, why?. Thanks very much for your advice. Surachai

Hi I don't see in your note any particular reasons why you couldn't. If it solders well and passes what ever specifications you are using than everything is OK. If your repair faces some soldering or rework challenges where a more agressive flux is

I got an inquiry from one of our electronics labs with regards to their soldering processes. They use eutectic (63% Sn, 37% Pb) solder. For liquid flux they are currently using Kester 186, which is an old-school, full rosin (RMA and ROL1) flux that c

Hi Dave, If my solder paste is RMA based and my Wave Solder flux is NC Based, will there be incompatibility problem that might arise during the process? thanks

Hi Dave, If my solder paste is RMA based and my Wave Solder flux is NC Based, will there be incompatibility problem that might arise during the process? And if i don't clean my boards what will be the possible effects of the residues left? thanks

Same query: Do we really need to clean the board with when using RMA ? I've been told that aqeous is not needed to clean the board, what cleaner is suitable and how?
