    Default Flux

    I use Kester 186 flux and am happy with it,
    but is there any better out there?

    Agreed, Amtech 559-UV is probably the best one out there... for lead-free stuff.

    For 60/40 Pb stuff, I prefer ammonium nitrate in petroleum jelly - the manufacturer is of no concern in that case.
    Careful what you wish for... You just might get it.

    Amtech-559 seems to have a shelf life of just 1 year; then again Kester 186 has a shelf life of just 2 years.

    The ammonia released is not annoying to the lungs or circuit board?

    Do you own a fume extractor? If you solder on a constant basis (at least once a week) you should consider getting one.

    Good point, for now I just use a fan to blow the fumes away; trouble is I'm usually so into a project that I simply forget.

    The short shelf life is not a problem if you don't buy tons of the stuff that you won't make use of in time.

    As for the fumes... I kinda like the smell, whatever it actually is. It's definitely not (just) ammonia, as that's offensive to me even in small quantities; and I always clean off excess flux straight away, as soon as everything cools off, with a combo of isopropyl- and ethanol-dipped non-fleecing cotton pads.

    Kester 186 is pleasant smelling although I am not sure it is great for the lungs; I have just over 1 fluid ounce, and it seems to be lasting even at room temperature. It cleans off quite easily with isopropyl alcohol; some people leave the flux on, but I prefer a clean board.

    For tough jobs I use low melting point alloy to help remove the component, copper braid to clean up the pads, and leaded solder for the replacement; with flux added throughout.

    I prefer the flux used in a flux capacitor.

    But the cost! the cost... prohibitive.
