[0002] In today's industrial production, especially in key industries such as electronics manufacturing, automotive parts, and building materials, the performance testing of thin film materials is crucial. As a common material performance evaluation method, the tear film test is primarily used to measure the adhesion between the thin film material and the underlying substrate. However, existing tear film testing technology has encountered many technical challenges during implementation, mainly manifested in the following aspects:

[0003] In actual film tearing tests, bubbles between the film and substrate are a significant factor affecting the accuracy of test results. The formation of these bubbles is often related to improper surface treatment, ambient humidity, and pressure control during operation. These bubbles can lead to uneven distribution of tearing force, thus affecting the accuracy of test results.
