Alumina ceramic is a ceramic material mainly composed of alumina (Al₂O₃), which is used in thick film integrated circuits. Film coating machines are also widely used in the preparation of alumina ceramic films.
Membrane method
The following is the film making method of the film coating machine in the preparation of alumina ceramic film:
Prepare samples: Prepare the required alumina ceramic membrane samples, and select the appropriate substrate (such as glass, silicon wafer, polymer, etc.) according to the experimental requirements.
Prepare solution: According to the needs of alumina ceramic membrane preparation, prepare corresponding solutions, such as alumina sol, organic precursor, hydrolysis reaction solution, etc.
Adjust parameters: According to the experimental requirements and sample characteristics, adjust the parameters on the film coating machine, such as coating speed, coating angle, coating pressure, etc.
Coating operation: evenly coat the solution on the substrate. Different coating methods can be selected, such as spin coating method, roller coating method, blade coating method and so on.
Film making: Use auxiliary equipment on the film coating machine, such as a rotary table, pressure-sensitive devices, etc., to fix the substrate at a specific position, and apply a certain pressure and angle to make the solution form a coating with a certain thickness.
Drying: Dry the coated sample at an appropriate temperature and time to fix the alumina ceramic film on the substrate.
Calcination: The dried samples are calcined at high temperature to make the alumina ceramic film form a crystal structure and improve its performance.
The application of the film coating machine can improve the efficiency and accuracy of the film coating operation, and the appropriate film making method can be selected according to different needs. In the application of alumina ceramic film, the use of film coating machine can prepare coating samples with different thickness and uniformity, which are used for performance testing, quality control and research and development in the fields of alumina film capacitors, sensors, dielectric materials, etc. wait. The use of the film coating machine can also improve the uniformity and stability of the coating, improve production efficiency and product quality.
