    Please describe your intended use so we can better help to answer your question..
    Hand soldering, machine soldering, required quantity?
    Are you required to be ROHS compliant? Leaded or leadfree?
    Any other necessary standards you must comply with?

    It would be for hand soldering. I am also looking for leadfree solder and ROHS compliant.

    You do not need solder paste or flux for electronics soldering.
    You buy solder wire with the resin already supplied in the centre core of the solder wire.

    My mistake not hand soldering. I would be using the paste for oven reflow. I would put the paste on the pads, add the components and put the boards in an oven.

    As for the flux I was asking because when I hand solder for example TQFPs, I use the drag soldering method. The flux I can buy locally comes in a spray bottle, which simply sprays too much flux. That is why I was asking for a recommendation for a flux pen.

    yes that link you first posted is fine for drag soldering. (flux paste or flux gel)
    As for solder paste..
    I've used the Chip Quick brand of solder paste in the syringe and it works great for hot air or reflow.
    If applying by stencil I get some in a nice plastic can so its easier to quickly appply to the squeegee.

    Just remember to keep the solder paste in the fridge between uses..

    and yeah its not cheap but a little goes a long way
