This 30-gram tub of rosin flux paste is exactly what you need for clean, reliable soldering on electronics.
It's made from high-purity rosin, so it produces very little smoke and hardly any smell – your workspace stays fresh, and your lungs thank you.
No nasty fumes, no harsh chemicals.

It's perfect for phone repairs, computer motherboards, or any delicate circuit board work.

One of the best things?


Use it with your favorite solder wire for consistent, shiny joints every time.
It's especially handy for tiny SMD components or fine-pitch ICs where precision matters.
Whether you're fixing a broken charging port or building a custom keyboard, this flux has your back.
And the compact 30g size is just right – not too bulky, but plenty for dozens of repairs.
