BEST Premium Quality Precision Soldering Paste (10g)

Pros: Easy to use flux in paste/grease form.
Doesn’t dry out.
Nice compact metal can.

Cons: Active agent is Zinc Chloride so this flux isn’t suitable for PCB soldering.

Other: Excellent product if used correctly, works great for making battery packs. If you’re careful to remove the flux residue it can be used for PCB soldering but a rosin based flux would be better.

Pros: Got this for a soldering project i was doing with a gamecube, i needed some flux/paste that would work real good on small electronic contacts like those on the GC, the paste/flux worked fine, it is only 10g tin, and you may think that isnt enough, but for fine electrical work like i was doing were you need so little even a 10g tin will last you a good few years possibly, providing you dont use it everyday :P, though if your a professional i guess you would buy the 50g tin anyhow xD

Cons: none really, great price, will last you a long time on fine electrcal jobs

Other: as long as your not trying to solder the wiring of a boeing 747 it should last a while :P
good price :D

Pros: Easy to apply (fingers do the job perfectly) Works well with SMD (components a few mm large are really easy to solder now) Cheap (farnell sales it for 4$, twice the price). Good quality (it works so well i wont buy any different brand)

Cons: Hard to open (shuts really tight) Box get greasy (and it came greasy as well in the mail, a bit annoying but it's normal)

Other: Really cheap, and works very well. It's hard to find in europe, because solder is supposed to contain flux, but it's not enough when you have to solder things that are a few mm large. That's when soldering paste comes handy
