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)

Works great for the projects I engage in. Draws the solder right in.

Good size container of flux for a reasonable price. Works well. Likely a lifetime supply for me. Containers are plastic these days - they open easier than the old-school metal ones that were impossible to open. Perhaps they crack in 30 years... probably not an issue.

Works Well

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.

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.

Works great, but remember to open a window or have good ventilation, as I stupidly used it in a closed room, causing my chest to hurt so badly from the fumes. Learning from my experience, I hope this will protect you and others around you.

This flux wax is perfect for soldering. I almost returned it after seeing more people use syringe flux, but I am glad I didn't.This flux is clean, and works well. I dip my solder in the wax and apply it to the board or just melt it onto the board with my iron and it works perfectly, no need for a syringe.I especially love that it is made in the USA, not many products are anymore so I really love being able to support the manufacturers who still produce products here. The quality is evident as well, this is a well-formulated wax, not some cheap Chinese junk.

Good quality
