The following is an X-ray fluorescence spectrometer used to test electroplated coatingsdetailed introduction：

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* %.

Report printing:

Can output reports in PDF and Excel formats, making historical data queries convenient

Safe use, maintenance and upkeep

Due to the high precision of the instrument, please do not open the instrument casing or make any changes to the X-ray source and detector without permission. Our company will not be responsible for any damage to the instrument caused by the user's own reasons.

The installation of the instrument must be smooth, and the distance between the back of the instrument and the wall must not be less than 30 centimeters. Standard 220V AC power must be used, and a stable voltage power supply must be equipped in case of unstable voltage.
