Vacuum plating equipment coating finished off the membrane

                     

  Vacuum plating equipment is the production of vacuum conditions most widely used devices. Vacuum plating equipment including many classes, such as ion evaporation, magnetron sputtering, electron gun, etc. Vacuum plating equipment of plating film with high hardness, corrosion resistance, surface smooth, beautiful wait for an advantage. Some customers reflect to us, sometimes coating products will appear off film phenomenon, this is how to return a responsibility? Today, chi shing small make up for the user analysis the cause of the coating product off membrane. Membrane layer falls off many reasons is very complex, we can analysis from the following points:
1, check the purity of the product surface
Cleanliness can affect the adhesion of coating on the surface of the coating product ability, keep the surface cleanliness can pass in the ion source amplification of argon, time delay during cleaning.
2, pay attention to the cleaning process
Are cleaned before coating, whether to have change of cleaning fluid.
3, coating process
Check the process parameters for change, for what time and current make appropriate adjustments.
4, the target material
Check the target material, such as titanium target, check whether the poisoning, to timely replacement.
5, vacuum chamber is fault
Leak detection on the vacuum chamber.
6, observe whether the product surface oxidation
There are several reasons for product surface oxidation, judgment and processing according to the actual situation.
Off membrane problems. According to the steps above analysis and ruled out.
