Electroplating X-ray Fluorescence Spectroscopy Coating Thickness Gauge: Accurate Measurement, Quality Assurance Choice

The electroplating X-ray fluorescence spectroscopy coating thickness gauge is a high-precision detection equipment based on the principle of X-ray fluorescence analysis. It is designed specifically for the electroplating industry and various coating thickness measurement needs, playing a key role in ensuring product quality and improving production efficiency.

Principles of Measurement Science*

The core principle is to use an X-ray tube to emit high-energy X-rays and irradiate the surface of the tested coating sample. After being excited, the elements in the coating will release secondary X-rays with specific energy, namely characteristic X-rays. By using high-resolution detectors to accurately capture the energy and intensity information of these characteristic X-rays, combined with built-in algorithms and standard databases, the thickness of the coating can be quickly and accurately calculated. This non-destructive measurement method does not require cutting, polishing, or other processing of the sample, preserving its integrity.

Outstanding performance characteristics and advantages

• High precision and high repeatabilityThe instrument adopts a precise optical system and signal processing technology, which can effectively reduce measurement errors, ensure high consistency and accuracy of each measurement result, and provide reliable data support for product quality control.

• Wide measurement rangeIt can adapt to the measurement of coatings with different thickness ranges, and can achieve accurate measurement for both micrometer level thin coatings and thicker coatings, meeting the diverse detection needs of the electroplating industry.

• Multi element analysis capabilityNot only can it measure the thickness of a single coating, but it can also measure the thickness of each layer in a multi-layer coating system separately, and analyze the elemental composition and content in the coating, providing comprehensive information for optimizing the electroplating process.

• Easy and fast operationEquipped with an intuitive human-computer interaction interface and intelligent operating software, users only need to undergo simple training to easily get started. The high degree of automation in the measurement process greatly shortens the detection time and improves production efficiency.

Widely applicable in various fields

Widely used in industries such as electroplating, electronics, hardware, automotive, aerospace, etc., it is used to detect the thickness of metal coatings (such as galvanizing, nickel plating, chrome plating, etc.) and non-metal coatings (such as plastic electroplating, ceramic coating, etc.), helping enterprises strictly control product quality and ensure that products meet relevant standards and customer requirements.

Coating detection:

Common metal coatings include:

Single layer thickness range:

Gold coating 0-8um,

Chromium coating 0-15um,

The rest is generally within 0-30um,

The minimum measurement can reach 0.001um.

Multi layer thickness range:

Au/Ni/Cu: Au analysis thickness: 0-8um Ni analysis thickness: 0-30um

Sn/Ni/Cu: Sn analysis thickness: 0-30um Ni analysis thickness: 0-30um

Cr/Ni/Fe: Cr analysis thickness 0-15um Ni analysis thickness: 0-30um

The number of coating layers is 1-6

The relative difference in coating accuracy is generally less than 5%.

Composition content of coating: Sn Pb alloy composition analysis; Composition analysis of Zn Ni alloy.

Advantages of Coating Analysis: The minimum size of PCB gold fingers can reach 0.2mm

Single layer analysis accuracy, taking Ni as an example: (relative difference)

Elemental composition analysis:

Analysis of plating solution: Currently, common plating solution element analysis includes gold, silver, tin, copper, nickel, chromium, and zinc.

ROHS and halogen-free detection, high-performance SDD detector can detect halogen-free, achieving multi-purpose coating and environmental protection.

Metal composition analysis can detect the content of other elements in metals while detecting ROHS.

Detection accuracy:

Heavy metals such as Cr, Cd, Hg, Cu, Zn, Fe, Ni, Pb, Mn, W, Au, Ag, Sn, etc

The detection limit is up to 1ppm.

The instrument has met the following standards for stable reading allowable differences in the analysis of these metal tests:

A. Stable testing for elements with a detection content greater than 5%, with a relative reading difference of less than 1%

B. Stable testing of elements with a detection content of 0.5-5%, with a relative reading difference of less than 2%

C. The stable test reading of elements with a detection content of 0.1-0.5% has a relative difference of less than 5%

D. Detect elements with a content below 0.1% and read relative difference with a change rate of less than 10%

Measurement accuracy:

1) Accuracy (single-layer):

Testing accuracy table of thickness gauge

Testing method: Under the same operating conditions, perform 5 tests on the same standard template, and compare the average data detected with the actual data of the standard template. The detection accuracy is the difference (average error) between the average detection value and the actual value of the standard sample

2) Two or more floors:

The accuracy of the first layer with two or more layers meets the test results of a single layer, but the second layer and above are more complex and need to be determined based on the thickness of the previous layer. When the thickness of the first layer is less than 2um, the testing accuracy of the first and second layers is basically consistent with that of a single layer. Referring to the following test report, the thickness of the gold standard sample for the first layer is 0.101um, and the thickness of the nickel standard sample for the second layer is 4.52um.

in When the thickness of a layer is between 2-5um, it will greatly reduce the testing accuracy of the second and third layers. The error rate of the second layer will be between 5-10%, and the error rate of the third layer will be less than 15%.

Repeatability:

Ensure repeatability value:≤±5%

Repetitive testing should be conducted after instrument calibration: under the same operating conditions, the same testing template should be used for continuous repeated testing. Continuous measurements must be taken at the same testing point using the same sample piece with an interval of 60 seconds. A total of 10 measurements should be taken, and each measurement value should be compared with the average of the 10 measurements.

Repeatability=Average Error ÷ Average Value × 100* %.
