FISCHERSCOPE X-RAY PCB series

FISCHERSCOPE X-RAY PCB series

The professional series for testing printed circuit boards

Today’s printed circuit boards have a vast number of coated contact points. In order to guarantee the reliability of soldered joints, corrosion resistance and shelf life, the respective thicknesses of the various materials must be in correct relation. For monitoring these tight specifications, energy-dispersive X-ray fluorescence is the method of choice.

Fischer's specially developed X-ray fluorescence instruments perfectly meet the requirements of PCB manufacturers: Not only are they fast and easy to use, all devices are spacious enough to accommodate PCBs up to 610 x 610mm in size. 

Various models are available depending on your requirements. Call us! We’re here for you.

FISCHERSCOPE X-RAY XULM-PCB

For simple measurements and spot checks, the FISCHERSCOPE® X-RAY XULM®-PCB is ideal. It’s equipped with a proportional counter tube detector, which makes for short measuring times. This X-ray fluorescence instrument is recommended for thickness measurements of layers more than 0.1µm thick.

  • Tungsten microfocus tube for standard applications
  • Proportional counter tube detector for analyzing elements from potassium (19) to uranium (92)
  • Fixed, wide sample stage for printed circuit boards up to 610 x 610 mm (24” x 24”)
  • Maximum sample height: 90 mm
  • Smallest measuring spot Ø approx. 0.2 mm
  • Certified fully protective device 

FISCHERSCOPE X-RAY XDLM PCB

The FISCHERSCOPE® X-RAY XDLM®-PCB is also equipped with a proportional counter tube. However, this X-ray fluorescence instrument has a variety of collimators and filters so you can create the optimal measuring conditions for your task. In the basic configuration, it has a pull-out sample stage, which simplifies positioning of the PCB. On request, a programmable XY stage is also available for automated measurements.

  • Tungsten microfocus tube for standard applications
  • Optional 3x changeable filter, for better excitation conditions for more complex tasks
  • Proportional counter tube detector for analyzing elements from potassium (19) to uranium (92)
  • Manually extractable or a programmable measuring stage for printed circuit boards up to 610 x 610 mm (24” x 24”)
  • Maximum sample height: 5mm
  • 4x changeable collimators, smallest measuring spot Ø approx. 0.2 mm
  • Individual approval as full-protection device 

FISCHERSCOPE X-RAY XDV-µ PCB

In high-reliability applications, printed circuit boards are quality-critical components. In such cases, high-end coatings according to the ENIG and ENEPIG processes are employed. Since the thinnest layer thicknesses in these processes are between 40 and 100 nm, the accuracy of proportional counter tubes no longer suffices to monitor the process. This is where the FISCHERSCOPE® X-RAY XDV®-µ PCB is the right choice. The combination of a highly sensitive silicon drift detector (SDD) and polycapillary optics allows for precise measurements on structures less than 50 µm in size.

Especially when dealing with very small structures, individually selecting each measuring position can take a lot of time if large numbers of random samples are to be inspected. But with the image recognition software implemented by Fischer, you can save yourself this effort. Simply store a section of the image; the XDV®-µ PCB searches for corresponding structures and measures them automatically.

  • Microfocus tube with tungsten or molybdenum
  • 4x changeable filter, for optimum excitation conditions for more complex tasks
  • Silicon drift detector for analysis of elements from aluminum (13) to uranium (92)
  • Programmable measuring stage, optionally with vacuum holder for FLEX PCBs
  • Polycapillary optics for very small measuring spots (10 or 20 µm FWHM) 
  • Maximum sample size: 610 x 610 mm and 10 mm tall
  • Individual approval as full-protection device
