Using the iFixit Soldering Splint is easy. First, place it on a flat surface and use the magnetic base to keep it steady. Then, position the wires you want to solder between the holders, making sure they're in the right place. You can adjust the wires as needed. When soldering, be careful as the soldering iron gets hot. Don't touch the soldering area immediately after finishing. To maintain the splint, keep it clean. You can wipe it with a dry cloth after use. Store it in your electronics toolkit to keep it safe and ready for the next project.
