: : : Traditional rosin fluxes are available in non-activated (R), mildly : activated (RMA) and activated (RA) formulations. RA and RMA fluxes contain : rosin combined with an activating agent, typically an acid, which increases : the wettability of metals to which it is applied by removing existing : oxides. The residue resulting from the use of RA flux is corrosive and must : be cleaned off the piece being soldered. RMA flux is formulated to result in : a residue which is not significantly corrosive, with cleaning being : preferred but optional. : : : I have a jar of RMA rosin flux... I assure you that it : contains zinc chloride. : __ : Steve
Naw Steve, what you have is a psychomatic hallucination induced by the power of suggestion ;-)

Look, fucktard!
Rosin flux for ELECTRONICS HAS NO ZnCl in it!
YOUR CRAP, is ACID flux, and MIGHT be rosinous in nature, but in no way does that make your remark that all rosin flux has ZnCl in it true in any way shape or form.
Get a clue, dumbfuck... you were and still are WRONG!

You've already admitted that my flux is rosinous... I never made a claim about electronics in any way.
I win.
It *is*, however, electronics flux of the RMA variety... 'non-corrosive' on the top of the tin. And I assure you that it kicks major flux ass, what with that touch of Zinc Chloride in it. I will also admit that it should be cleaned off after use.
If you went into an electronics shop in the '60s, you'd find one of these tins... and some poor schlobb sniffing the fumes of such. I don't know about the long-term hazards, but I *do* know, first-hand, about 'zinc headache'... and it *does* suck, bigtime. Doesn't take much, and I only got a small taste (thank FSM!). It was from welding, not soldering. __ Steve .

Sure. I iterated it OVER AND OVER.
You inferred that ALL rosin flux has Zinc Chloride in it, and
A: That is NOT, nor has it ever been true. and
B: ACID flux, which is what you have, is in no way meant for use in electronic assemblies. I don't care what the retarded maker printed on the can, you stupid fucktard!
And C: There is absolutely no indication on that tin that the contents are "rosin flux".

You got the shit part right, but you didn't get any further.
You do however prove again, that women have the prerogative to change their mind at will, and men have the ability to justify anything. Just as you're are attempting to do here.
Fact is., you lose. You lost from the get-go, and you know it.
I beat you about the head with my Irish net shillelagh, and you are still reeling from it.
Again, you are clueless as to logic. Shall I throw him his bone? Or her... I suppose a woman could have a MassivePrawn grafted on, or strapped on... is your prawn strapped on?
Yes, it does.... it's very nice!
I just did! I also posted a Wiki describing rosin flux with 'activation', otherwise known as ZnCl2.
I showed you the flux... so I win. It's very simple! I've met the condition you just (so disengenuously) set. __ Steve . maybe the bone next time
