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 Clean Residues with No Goopy Mess (2oz Jar)

This is probably the best flux paste I've used. I've been an electronics technician for almost 50 years and I have not found a better paste flux for tinning tips and wires. I had to repair the wiring on my lift chair hand control which required tinning several wires. Just a tiny amount made the iron tip clean and let the solder flow smoothly. I had worked for OEM and contract manufacturers that never had this grade of paste. Don't buy the cheap stuff. If you do, you will probably use twice as much with questionable results. Spend a little more for this, you'll be glad you did.

The quantity of this product is amazing for the price. You only need a very small amount to get most jobs done, so this will last me quite a while. This is so easy to use and works fast. It’s not too thick and not too thin rather just right. I used this product to help me clean the ends of a tape measure I sanded for my ham radio tape measure antenna. This enabled me to solder the cable wires to the tape measure with ease. The joint bonded much stronger with the use of this flux. I highly recommend this for both those new to soldering and seasoned soldering experts.

HELLO EVERYONE, CLEAN, ALMOST NO RESIDUE, NICE FLUX, WELL WORTH THE MONEY, PERFECT SIZE,

There's almost no stickiness, it's a thick paste, so it may be a bit tricky to apply accurately, this can make your accuracy a bit off, it's quick and easy use most of the time, and the container comes in a pretty decent sized jar. accuracy

I don’t do too much solder repair, but I’ve learned that you need the proper tools and equipment to perform the job adequately, whether that be a new or repaired solder joint. Keep in mind, the only repairs I work on are mostly car related, for example, when capacitors or resistors go bad. This flux works well in those applications, simply brush a little on, and it helps clean and create a good solder joint.

I'm new to soldering and it was recommended to me that I use flux when I solder because I was having such a hard time with it. Flux makes the solder smooth like butter. The solder instantly melts when it touches an area heated with flux. Before it seemed like it was taking forever for the solder to melt and when it did it instantly got hard again. Flux made it easy. Like applying hot butter onto a piece of toast.

Doesn’t eat wires. Works well with different kinds of solder and at different temperatures. Easier to clean off than other brands I’ve tried.

Great product that made my workflow effortless! Thanks again!

This is good flux

I used one of those cheap fluxes and boy oh boy what a difference! However it's best to use it by putting it first into a syrnge equipped with a hollow needle of about 0.7 - 1 mm inner hole diameter. That will help immensely with the application

This rosin paste flux works well for soldering. It helps the solder flow smoothly, resulting in clean joints. The jar size is good for my hobby use.
