With high-purity natural resin, the Soldering Rosin Hard Solder Flux cleans copper surfaces during soldering flux for iron repair. Under electric iron heat, solid paste form melts to clear oxides immediately. Across PCB pads, it facilitates solder flow without leaving corrosive residue.
Key Features
- High Purity Resin: Refined natural rosin composition with zero synthetic fillers. Prevents joint contamination during delicate PCB repair.
- Oxide Removal: Chemical reaction strips oxygen layers from metal surfaces. Solder sticks to clean copper without balling up.
- Non-corrosive PH: Neutral chemical balance avoids eating through circuit traces. Safe for long-term electronics storage in high humidity.
- Hard Paste Form: Solidified amber resin melts only upon iron contact. Won't leak or spill inside your toolbox.
Frequently Asked Questions
What is soldering rosin used for?
Rosin removes oxide films from metal surfaces to improve solder adhesion. It creates a clean bond between the iron and electrical components.
Is rosin flux conductive?
Solid rosin acts as an insulator and does not conduct electricity. It remains non-conductive after cooling, preventing shorts on dense circuit boards.
