The plasma washer removes the metal oxide
Chemical cleaning: surface reaction to chemical reaction-based plasma cleaning, also known as PE.
Example: O2 + e- → 2O ※ + e-O ※ + organic → CO2 + H2O
It can be seen from the reaction, oxygen plasma through the chemical reaction can be non-volatile organic matter into volatile H2O and CO2.
Example: H2 + e- → 2H ※ + e-H ※ + non-volatile metal oxide → metal + H2O
From the reaction can be seen, hydrogen plasma through the chemical reaction can remove the metal surface oxide layer, clean the metal surface.
Physical cleaning: surface reaction to the physical reaction of the main plasma cleaning, also known as sputtering corrosion (SPE).
Example: Ar + e- → Ar ++ 2e-Ar ++ Contamination → Volatile contamination
Ar + is accelerated by kinetic energy under self-bias or external bias, and then bombardes the surface of the workpiece to be cleaned. It is typically used to remove oxides, epoxy spills or micro-particulate contaminants while activating surface energy.
