I was going to order a syringe flux product before I watched a lot of soldering videos on You-Tube;
By H. Martiuk
After researching smt soldering flux options online, I was just about to purchase a syringe delivery type flux product purported to simplify smt rework. However, after closely viewing a significant number of soldering technique YOU-TUBE videos, I came across one where a tech was using good old, tried and true, rosin paste flux and easily applying it with a metal pick tool.
Whereas the syringe fluxes were used in most of the videos, after seeing the tech easily apply a controlled small amount of paste flux with a pick and further seeing the same quality finished solder connections, I decided tried and true was actually better than new. Although some syringe products seem to form an preliminary bond that holds the small smt components in place, I prefer to tin a pad and tack the component, especially when syringe flux products have expiration dates and tried and true does not.
I highly recommend tried and true, ROSIN paste flux for all rework electronic soldering.
Order arrived promptly via US mail. (3 days) Very satisfied with this purchase

Rosin paste flux
By GMan
This rosin paste flux works well for precision electronic PCB and wire soldering. I prefer paste over liquid because it is easier to apply - use a small acid brush or Q-Tips. Make sure to clean residue off with isoprop alcohol (=rubbing alcohol) after finishing the soldering to avoid long-term corrosion that any flux will cause. This flux in particular helps tinning old wires and facilitates perfect joints when soldering on oxidized and/or cheap circuit boards (i.e. most consumer electronics and appliances).
I'll purchase more of this when my current jar runs out.
