Soldering Paste (15g)

Soldering Paste is an essential consumable for achieving reliable and professional solder joints in electronics manufacturing, repair, and assembly. Whether you are working on PCB prototyping, SMT component mounting, or fine-pitch soldering tasks, this premium soldering paste ensures excellent wetting, smooth flow, and strong conductivity. Designed for hobbyists, technicians, and industrial users, the paste significantly enhances soldering precision while reducing defects such as bridging, voids, and cold joints.

Formulated with a blend of pure metal alloys and high-active flux, this soldering paste provides superior performance across a wide temperature range. It melts cleanly, adheres firmly, and produces uniform joints even on complex or miniaturized circuit boards. If you’re looking for a reliable medium to improve your soldering efficiency and component bonding strength, this soldering paste is the ideal choice.

Key Features of Soldering Paste

1. Excellent Wetting and Bonding

The solder paste ensures strong mechanical bonding and efficient wetting on copper, tin-plated, nickel-plated, and gold-plated surfaces. This results in clean, shiny, and robust solder joints.

2. High Electrical Conductivity

Formulated with a high-purity alloy composition, the paste delivers superior electrical continuity, ensuring dependable signal flow in high-performance circuits.

3. Smooth and Consistent Texture

Its uniform particle size and creamy consistency allow precise application using syringes, stencil printing, or manual placement without clumping or drying quickly.

4. Low Residue and Non-Corrosive Flux

The flux core leaves minimal residue after reflow, reducing the need for post-cleaning. It is also non-corrosive, making it safe for sensitive electronic components.

5. Stable Performance Across Temperatures

The paste maintains stability during storage and performs well in standard and high-temperature soldering processes, including hot air rework, reflow ovens, and soldering irons.

6. Ideal for Fine-Pitch Components

Perfect for SMD/SMT components, integrated circuits, microcontrollers, and miniature pads where precision is critical.
