Near-Infrared (NIR) Coating Thickness Gauge for the Web Coating Industry

This technology measures dried finished coatings and provides predictive measurement of wet coatings. It helps identify process deviations caused by the coating head or oven in advance, significantly reducing waste caused by uneven thickness. Compared with radiation-based thickness gauges, the NIR solution eliminates the need for radiation protection and periodic calibration, making it ideal for high-volume, continuous production scenarios such as coating, film, lithium battery, and packaging tape manufacturing.

X-ray Thickness Measurement Technology Empowers PI Film Production with Non-Contact, High-Precision Inline Thickness Control

Polyimide (PI) film is widely used in critical fields such as flexible circuit boards, chip packaging, displays, and power batteries, owing to its excellent high/low-temperature resistance, high insulation, and high mechanical strength. Thickness accuracy directly determines the insulation performance and reliability of the finished product. Micron-level thickness variations can degrade device performance and lead to product scrapping. Traditional offline sampling inspection has lag issues, making it difficult to capture local thickness fluctuations on high-speed production lines in real time. Contact measurement can easily cause compression damage and scratches to ultra-thin PI films, restricting yield improvements for high-end electronic-grade PI films.
