How is tape tested for thickness? transparent tape factory

The transparent tape production factory shares with you: thickness measurement is divided into two types: online test and off-line test. The earliest used for film thickness measurement is the off-line thickness measurement technology. After that, with the continuous development of ray technology, the online thickness measurement equipment installed with the thin film production line was gradually developed. Online thickness measurement technology is completely different from non-online thickness measurement technology in test principle. Online thickness measurement technology generally adopts non-contact measurement methods such as ray technology, and non-online thickness measurement technology generally adopts mechanical measurement method or is based on eddy current technology or electromagnetic induction. The principle measurement method also adopts optical thickness measurement technology and ultrasonic thickness measurement technology. transparent tape factory
