Scanning Thin-Film Thickness Measurement System

X-rays are penetrating: the source emits rays that pass through the film being measured, causing attenuation, while the detector measures the attenuated radiation intensity. For a given material, the attenuation coefficient remains constant; as the film thickness increases, the detected radiation intensity decreases. Based on this principle, the current film thickness can be accurately determined, making this method suitable for measuring various transparent films, barrier films, and opaque colored films.

Product Description

Working principle

The measurement probe is mounted on a high-precision O‑type scanning frame and performs synchronized scans via a servo control system. The system software incorporates variables such as the equipment’s scanning speed, rotational speed, traction speed, and operating temperature to calculate the thickness distribution profile and associated thickness parameters at each point of the mold.

It features online calibration, data storage, data retrieval, and data transmission. The system operates at an X-ray energy level below 5 kV, ensuring safety and environmental friendliness, and is an internationally recognized, environmentally exempted radiation‑safe product.

Advantages

Suitable for various transparent films, barrier films, and non-transparent colored films.
A 5 keV low-energy, high-precision transmission X-ray probe that is safe and environmentally friendly, compliant with national exemption regulations for radiation sources.
Accurately measures the thickness of 10–200 µm PE or PA films, with a measurement accuracy of 1‰ or 0.1 µm.
Non-contact continuous measurement with rapid response (1–20 ms) and no measurement latency.
Full-range measurement coverage, with a high-precision scanning frame spanning the full size: 700 mm to 4,000 mm.
The O‑type scanning gantry is manufactured using CNC precision machining, ensuring measurement accuracy and stability.
The probe houses all electrical components, and the entire through‑type probe consists of two sub‑probes—one upper and one lower—mounted on the scanning gantry.
The upper probe comprises an X-ray detector, a signal-processing card with proprietary intellectual property, and a communication card.
The probe assembly comprises an X-ray tube, a high-voltage generator, and signal-processing and communication cards developed with proprietary intellectual property.
The probe is cooled by purified compressed air, maintaining the probe and its surrounding environment at a temperature below 60°C, thereby enhancing measurement accuracy and extending service life.
High-precision servo closed-loop positioning control system; the algorithm software can accurately measure up to 1,000 points of the film thickness distribution curve within a 20-second scanning cycle.
Integrated installation ensures simple maintenance, and it features remote diagnostics and commissioning capabilities.
