To desolder an IC chip using hot air or a rework machine, the technician first applies flux to the solder joints to help facilitate the desoldering process. Then, the hot air or rework machine is used to heat the solder joints to the melting point, allowing the chip to be lifted off the circuit board. Care must be taken to ensure that the surrounding components are not damaged by the heat, and the process may require multiple passes to fully remove the chip. Once the chip is removed, any remaining solder on the circuit board can be cleaned off using a desoldering braid or vacuum pump. **
