Default Re: Extra flux anyone?

Fluxite.
I would add a word of caution to Kevin (McMurdo) comments.
"modern" Fluxite contains zinc chloride, which will corrode away your joint and board very quickly. Washing with a solvent (IPA or whatever) does not remove any ZnCl/HCl occluded in the joint itself.
Look at the tin. The one I have warns clearly. See picture 2 below.
But I also have original pre 1960? tins, which is non- corrosive. I still use it, and if anyone wants a bit, send me a PM.
See my posting of 26 July 2017.
Three pictures. The first two are of the "modern" corrosive version, with the red devil. The third is the non-corrosive one, with a green devil, except that Kevin has a green devil on a presumably corrosive tin. Maybe, single colour printing on the tin is now preferred.
