Solder paste vs. flux for reflow.

I want to try reflow soldering at home. I got a recommendation to use Kester EP256 solder paste.
Since I am only trying, I don't need so much. Where can I find solder paste in small tubes?
I looked on ebay for "solder paste" but all the results I get looks like flux (although it says "solder paste"). So how can I know if what I buy is just "flux" or "solder paste"?

Bottom line, I need a small tube of solder paste to try out reflow soldering. I prefer buying it on ebay...

Kester makes 35 gram (10cc) tubes:

7016070520 63/37 solder in no-clean flux $36.75
7017080520 63/37 solder in water soluble flux $36.75

Chip Quik Inc makes 15 gram (5cc) syringes that come with an application needle.

SMD291AX $13.35

They also have 35 gram (10cc) syringes with needles.

SMD291AX10 63/37 solder $19.85
SMD291SNL10 lead-free solder $22.31

Prices are from DigiKey.com

The guy I bought from on ebay doesn't list any for sale currently. He was repachaging into syringes and I think I got mine for around US$10 a couple of years ago; I'm still using it.

Be careful, because there's some confusion among some sellers (seems to be a translation problem, maybe) about the difference between "paste flux" and "solder paste". Paste flux is just that, flux in a paste form (as opposed to liquid) - there's no solder in it. Solder paste is solder with the flux mixed in.

I got some paste flux from deal extreme. It worked, but was a bit stiff, and not easy to dispense.

If it doesn't come in a syringe, get yourself some syringes and some dispensing tips. I bought something like this so I had room to experiment. You want dispensing tips, not needles - needles are sharpened, dispensing tips are not.

Thanks for all the tips.
The magic phrase I was missing is 63/37... running a search with this phrase gives better results.
I ended up ordering this for around $5 and a set of 100 tips for $12.50 from here

FYI...

looks similar to the solder paste I have gotten from www.dealextreme.com

(free shipping always).. shipping takes A LONG time to get to the US though.. not sure about Israel :slight_smile:

syringes too if you search.

if doing MANY boards.. maybe invest in a solder mask/stencil...

BTW Paste flux is used for soldering water pipes by plumbers - it is not rosin flux, it is highly acidic
and must never get anywhere near electronics - and must never be used without eye protection either.

[oh yes, and if you are going to use lead-based solder paste you'll should wear gloves since you don't
want to get it on your skin, its not easily removed by soap and water. Lead-free solder paste is available]
