Smart Solder revolutionizes the soldering process by combining the filler material directly with the soldering tool. The advanced extrusion mechanism ensures a steady and controlled flow of material to the soldering tip, while the Arduino NANO microcontroller allows for precise adjustments in extrusion speed, melting temperature, and material quantity. This integration results in a more efficient, precise, and user-friendly soldering experience, making Smart Solder the ideal tool for both delicate electronic components and robust metal joints.
