Teach You To Find Out The Reason Why The Products Coated With Vacuum Coating Equipment Fall Off The Film

Vacuum coating equipment mainly refers to a type of coating that needs to be carried out under high vacuum, and there are many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition and many others. There will also be many problems in the use of vacuum coating equipment, such as film peeling of the plated products. Next, we will introduce the reasons for the film drop of the products plated by the vacuum coating equipment.

1. The cleanliness of the product surface is not enough, and the ion source cleaning argon amplification time is too long.

2. Whether the cleaning agent is added during cleaning, or the cleaning agent is replaced, it is recommended to use pure water to try it first.

3. Whether the process parameters change, some adjustments can be made in the film thickness and current.
