Temperature: 608 

°F ± 68 °F (320 °C ± 20 °C)

• 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.

If you don’t have special tools (ex. Hot air disordering tool), conduct the following operations.
