3 Overview

X-ray fluorescence coating thickness gauge is an energy dispersive method based on non-destructive quantitative analysis instrument with points Analysis of measuring a variety of metal materials composition and features a variety of coating thickness, widely used in electronics, semiconductor, jewelry, wood Analysis of materials and other industries. X-ray fluorescence coating thickness measurement of coating thickness principles. X-ray tube primary X On irradiation of the sample to be analyzed, the sample is excited to a secondary X-ray radiation to the detector, the second Energy radiation having a wavelength and characteristics of the sample material, coating thickness, and secondary radiation intensity of a certain relationship, the more Channel analyzer spectrum analysis and computer processing to calculate the coating thickness of the test sample. X-ray fluorescence coating thickness gauge working principle is shown in Figure 1. Figure 1 X-ray fluorescence coating thickness gauge working principle diagram

4 Metrological characteristics

4.1 Thickness measurement repeatability Coating thickness measurement repeatability of less than 3%. 4.2 shows the value of stability 1h shows the change in the value of the instrument is not greater than the maximum permissible indication error. 4.3 Thickness measurement indication error Technical agreement acceptance by users and manufacturers reached between the parties, when recalibration by the user's requirements. Note. Due to calibration measurements are given only, not qualified to judge whether or not the measuring properties are for reference only.
