Rosin Paste Flux #135 (FLS135) 2oz from Amazon

Just a quick review of the Rosin Paste Flux #135 2 oz jar from Amazon. It has a 4.7 star rating on Amazon for good reason. Also posted this with my Amazon review.

Please be kind, I do suck at soldering and was never trained to solder the "proper" way, but after hearing so much about flux, I decided to give it a try and it makes things so much easier to solder, especially small stuff! I don't have steady hands either, which you can see, which is why this stuff really helps.

Very good, excellent demo. I didn't have much success with a solder flux which had a 63/37 alloy and not cheap. That needed more 63/37 solder on top of what was in the paste! I will give this one a go. Cheers.

This is EXACTLY what I was looking for.
Thank you so much!

SRA also sells a no clean version (135NC) that is supposedly less corrosive for circuit board work. You definitely need to clean up the board with isopropyl alcohol since rosin activated flux is corrosive.

I have the same one, it feels like it will never run out.

Thank you kindly for your demonstration!

This stuff crystallizes fast. In fact, when I bought a can, it was already hardened, making it difficult to properly apply. I wasn't aware that the consistency was meant to be more of a paste, so I didn't return it.

If you buy this stuff, be sure to use it fairly quickly, otherwise you'll have a hardened tub that's more difficult to apply to your work surface.

Nice. Can u use it on rvs and aluminum?

...new to all this, do you need the flux and what is it exactly, as in what is it supposed to do when soldering?
Bought a soldering kit a few weeks back but haven’t used yet.
Buying a heat gun for another project and ran into _Sra Rosin Paste Flux_ and was wondering if I needed it?

What are those crystals on the paste?
I have those crystals on mine too

[carls.]

so whats the difference between the this version the #135 and the no clean past flux #135NC??

[so-calsoccer]

Is this type of flux used to remove diodes and put back in as well?

[kyleelam]

I bought this stuff for like 8 bucks. Great stuff!

And I thought for a second this was marijuana rosin sold on amazon.

60/40? Try the liquid flux in a small bottle innyour next video

Lol I was doing it all wrong dabbing the soldering tip into it instead of applying it.
