SRA Solder 135 Rosin Paste Soldering Flux For Electronics, No Clean Flux Made for Lead and Lead-Free Solder Circuit Boards and Copper Electrical Wire - Safe Residues with No Goopy Mess (2oz 2-Pack)

Every person that solders repairing electronics experiences wire that is old, cheap and very little copper in it. When your trying to solder those kinds of wire youll spend time heating the wire and it will not accept solder! I use a wire brush or sandpaper to clean the wire ends then use a dab ot this rosin paste. The solder then is absorbed into the wire giving you a faster and stronger joint. Professional electricians use rosin paste regularly. It is the only way you'll get cheap solder to work. Also works great when reheating an old sloder joint to attach new wire to it.

The SRA Solder 135 Rosin Paste Soldering Flux makes soldering my circuit boards a breeze, flowing nicely with no messy residue. The 2oz jar is easy to dip into, but it can dry out if you don’t seal it tight after use.

Nice paste for soldering.

I generally just use flux paste when de-soldering, this paste works well and cleans up easily.

Its Flux, It works!

This was the first flux I ever bought and it made a world of difference. I tried to make my own liquid flux and a real paste to put in a syringe with 91% and 95% ipa. It didn’t work very well at all. I got a tiny amount of liquid flux but a paste is pretty much impossible to make with this drug and ipa. I found it hard to use the proper amount of flux and put it where I want it so I’m more of a paste in a syringe guy but this stuff is still useful. It’ll last you a long time

Works great

Good product
