12.2. How to Replace the Shield Case
12.2.1. Preparation
• PbF (: Pb free) Solder
• Soldering Iron
Tip Temperature of 700
°F ± 20°F (370°C ± 10°C)
Note:
We recommend a 30 to 40 Watt soldering iron. An expert may be able to use a 60 to 80 Watt iron where someone with less 
experience could overheat and damage the PCB foil.
• Hot Air Desoldering Tool
Temperature: 608
°F ± 68°F (320°C ± 20°C)
12.2.2. Caution
• To replace the IC efficiently, choose the right sized nozzle of the hot air desoldering tool that matches the IC package.
• Be careful about the temperature of the hot air desoldering tool not to damage the PCB and/or IC.
12.2.3. How to Remove the Shield Case
