The Rosin Soldering Paste (100g, High Quality) is a flux material widely used in soldering to improve the quality and strength of solder joints. It helps clean, prepare, and protect metal surfaces during the soldering process. 🔹 Key Features: Composition: Primarily made of natural rosin with additives to improve solder flow. Weight: 100g (sufficient for long-term hobbyist or professional use). Function: Cleans oxidation and prevents re-oxidation on metal surfaces while soldering. Appearance: Yellow to light brown sticky paste. Usage: Compatible with both lead-based and lead-free solder wires. 🔹 Benefits: Ensures strong, shiny, and durable solder joints. Reduces oxidation and corrosion during soldering. Provides smooth solder flow and better adhesion. Helps in soldering fine electronic components by reducing surface tension. 🔹 Applications: Electronics repair and assembly (PCBs, Arduino, IoT modules). Electrical wiring and small appliance repair. Hobby projects requiring precise and reliable soldering.
