Solder Paste needle

I'm buying my first tube of solder paste. Do I need extra needles, or will one suffice?

Does the paste inside the needle have a shorter shelf life than the paste inside the tube?

I mixed my own paste/flux solution and loaded my own syringe, so it’s not exactly the same circumstances, but I haven’t had any problem with the needle itself. I did have to mix a bit more flux into the tube recently though.

Sounds great :-) - So you mix flux with ... what? Is it possible to buy solder as powder?

So you just use one needle?

I bought a syringe and needle from a farm supply store, and the cheap “mechanics” solder paste from fasttech. Then I mixed some kester liquid flux into the solder paste so it is thin enough to go through the needle.

Ok -thanks!

Just so you know, that’s what I did, but if I was doing it again I would just buy a pre-packed syringe. It was too much hassle for the small cost savings.

Roger that :-)

Nice to know that it's possible to make your own. But I'll buy a pre-packed syringe
