The 2UUL SC31 Soldering Wire is high-quality tin lead solder wire with a melting point of 183℃, sized 0.3mm and net weight 50g. It is specially made for micro soldering, PCB repair, component welding and delicate electronic rework. It features fast melting, great fluidity and reliable conductivity, delivering stable welding performance and neat solder joints. It is an essential tool for professional electronic maintenance.

⚡ 183℃ Low Melting Point: Melts quickly at 183℃, requires low heating temperature, effectively prevents heat damage to sensitive micro components during soldering.

🔍 0.3mm Ultra-Thin Diameter: Fine wire design, ideal for tiny solder points, dense components and narrow gaps, enables ultra-precision soldering work.

🛡️ Good Fluidity & Adhesion: Smooth melting, solder flows evenly and adheres firmly to pads. Effectively avoids virtual soldering, cold soldering and broken joints.

✨ Bright & Neat Solder Joints: Produces glossy, tidy solder points with few slag residues, improves welding appearance and yield rate.

🌫️ Low Smoke & Mild Odor: Generates little smoke during use, creates a comfortable working environment for long-time repair operations.

📦 50g Portable Pack: Moderate net weight, easy to store and carry. Perfect for daily repair use and personal tool kits.

Make sure the device is fully powered off. Clean the soldering spots to remove dust, oxide and impurities, keep the surface dry and clean.

Preheat the soldering iron to proper temperature. Touch the soldering wire to the target position gently, let the melted tin cover the solder pad evenly. Remove the wire and iron after forming a full solder joint.

Control the heating time to avoid overheating the circuit board and components. Keep the product sealed and stored in a cool dry place, away from moisture and high temperature.

Perfect for fine soldering of smartphone motherboards, small chips, pins, connectors and FPC lines.

Suitable for repairing tiny solder joints, replacing miniature components on laptops and tablets.

Ideal for SMD components, micro circuits, small ICs and other delicate electronic welding work.

Widely used for small household appliances, digital gadgets and various precision electronic maintenance.
