X-ray fluorescence coating thickness tester EX-851

X-ray fluorescence coating thickness tester EX-851

Equipped with auto focus
Select two measurement modes to make measurement work smoother

・Full auto focus mode
⇒Set the measurement object at the irradiation position of the laser pointer and close the door.
The stage moves automatically, and the measurement is automatically performed
・Semi-auto focus mode
⇒As with the above full auto focus mode, when the object is set
and the door is closed, the stage moves automatically and performs the action of focusing

Features of X-ray fluorescence coating thickness tester EX-851

Auto focus

Position the measuring unit to the position of the laser pointer, move it to the measured value automatically and measure only by closing the door.

Automatic measurement stage

By aligning the mouse to the measurement position, quick alignment is achieved.Also, if the measurement position is registered, continuous automatic measurement is also possible.In addition, coordinate correction, channel link, corresponding to various patterns.Standard board calibration can also be measured automatically.

Double filter adopted

In addition to the numeric filter, the mechanical filter (double filter) can be used to measure under optimal conditions so as to always obtain the highest accuracy.

Full report preparation function

By adopting MS-Windows software, you can easily capture the measurement screen and have a full report creation function.The multitasking feature allows other processing, including reporting, even during measurement.

5 types of internal organs

The minimum diameter of the collimator is 0.1 mm and can measure very small parts.Standard・0.1,0.2,0.5,1.0,2.0
In addition, two special specifications are available as options.
・0.05,0.1,0.2,0.3,0.5
・0.05×0.5,0.5×0.05,0.1,0.2,0.5

Self-diagnosis function and X-ray tube maintenance function

Self-diagnosis function enables quick solution to equipment troubles.In addition, X-ray tube use time and endurance time display function has been added to support maintenance safety.

Spectral display during film thickness measurement

Spectrum analysis high-speed processing by multi-channel, spectrum display of the object is performed by simple operation.(Processing speed about 2-3 seconds)

Display of measurement unit monitor image

Load the X-ray irradiation unit on the Windows screen and display the X-ray irradiation unit.The collimator makes it possible to change the magnification ratio.

Visually display the plating adhesion distribution of the object to be measured

Three-dimensional graph display makes it possible to understand the plating thickness distribution of the measurement object at a glance.

 

 

About performance improvement (high accuracy) by Be window X-ray tube (option)

   

We have prepared Be window X-ray tube (option) for X-ray fluorescence film thickness meter EX-731.
By using this option, it is possible to improve the measurement accuracy repeatedly for Cr measurement and Ni measurement.

       

Explanation on performance improvement

     

The high energy (high atomic number) Sn measurement is the same as before, but the low energy (low atomic number)
In the case of the surface layer Au in the two-layer measurement, the interlayer Ni is improved by about 20% due to the improvement of accuracy although it is small.n the case of the film thickness meter of the fluorescent X-ray method, the repeat measurement accuracy (standard deviation) is due to statistical fluctuation in the generation process of the obtained fluorescent X-ray intensity, and Be window X-ray tube (option) is applied These results indicate that, in the case of Cr, about 9 times or more fluorescent X-ray intensity is obtained compared to the conventional standard machine.Therefore, measurement with the same accuracy as conventional becomes possible in a short time.
Please consider using this Be window X-ray tube.
