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)

SRA soldering paste is the best I've ever used. It facilitates wetting multi-stranded wire when pre-tinning the soldering connection. It also provides better adhesion, without increasing soldering iron temperature. Great job SRA and great product.

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.

I like SRA products I have never been disappointed. Used this already to reflow a chip in a car radio with known issue of the chip detaching to the point of radio not working. Did a fantastic job, and reflowed existing solder to a nice shiny result. All is well now, a leaves no leftover residue either!

Seemed to work fine. But has issues with the quality of metal so couldn't get a good solder. But I don't think it was a fault of this solder.

works on lead and non leaded solder I used on both types of solder with excellent results good price i found less is best I did clean solder joints once cooled I noted container which solder comes in looks to be robust for storage. If needed I'll buy this brand again

Great product makes soldering a lot easier

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.

Gets the job done

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

Excelente

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.
