Using the iFixit Professional Soldering Splint is a breeze. First, find a suitable ferrous metal surface and use the magnetic base to attach the splint. Then, place the wire you want to solder into the holding area. Make sure the wire fits well and is secure. Now, you're ready to start soldering. Remember, the splint can handle up to 30 seconds of direct contact with a 350 C soldering iron, but try not to exceed this time to avoid damaging the splint. When you're done soldering, let the splint cool down before moving it. For maintenance, simply wipe it clean with a dry cloth. Keep it in a dry place to ensure its long - term performance.
