Soldering, desoldering, and rework products are essential tools for assembling, modifying, and repairing electronic components. Soldering joins materials using molten metal alloys, desoldering removes solder to detach components, and rework involves correcting or modifying existing solder joints. These processes are critical in electronics manufacturing, repair, and prototyping, ensuring reliability and functionality in devices ranging from consumer electronics to aerospace systems.
