A solder wire classified as L0 under IPC J-STD-004 means that the flux residues can be left on the board safely, and when you select this type of cored wire the intention is not to clean. You just select a solder wire that gives you an acceptable lev

I have always been under the impression that you want the flux make-up of your cored wire and supplemental flux (squeeze bottle) to be as identical/compatible as possible. I was just looking over a manufacturers datasheet for a resin-based cored wir

Just skip the squirt bottle and your problem is solved. Cored solder has enough activity for proper wetting. When occasionally extra activity is needed use a fluxpen.

I should have mentioned... the only flux we use for the hand soldering is wire-core, no bottle flux. I think it should be a non-issue to leave the activated wire core flux residue. I'm just looking for some way to prove it to the designer.

Thanks Patrick, also IPC-HDBK-001 explains even better then IPC-J-STD-004, but unfortunately not yet infos about flux for L-F soldering.That's why I am trying to get some infos more from experienced people. Some L-F (SAC or SACX) cored wires vendor

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
