Therefore, there is an advantage that it can be used in the same manner as the conventional single fluorocarbon, and does not require a large change of the conventional technology.
Also, it is more suitable as a cleaning solvent instead of R113 because it has better dissolution and removal properties of flux and oil than R113 which is often used as a solvent.
