FISCHERSCOPE Xray Technology Optimizes Industrial Quality Control

XRF analysis relies on a straightforward physical principle. When a sample is irradiated, its atoms absorb energy and release secondary, or fluorescent, X-rays whose energies are specific to the elements present. By measuring those energies and their intensities, an instrument can identify which elements are in the sample and in what proportions, or calculate how thick a coating sits on a substrate.

Because the method does not require a probe to contact the part, it preserves surface integrity, an advantage for high-value components and delicate electronic assemblies. Measurements are typically completed in seconds, which allows the technique to be deployed both in laboratory development work and alongside a production line.

The measurement platform combines several hardware and software components intended to balance speed against accuracy.

• Detector options: configurations include proportional counter tubes, silicon PIN detectors and silicon drift detectors (SDD), selected according to the resolution and sensitivity a given application demands.
• WinFTM software: the control and evaluation package at the center of the system handles data transfer, depth assessment and export of results, streamlining the analysis workflow.
• Application flexibility: the line spans benchtop, portable and semi- or fully automated systems, covering everything from laboratory research to in-line inspection on a production floor.

The choice among these configurations is generally driven by the size and geometry of the parts being measured, the elements of interest and the throughput the operator needs to sustain.

Instruments in the family are differentiated primarily by the sample types they are designed to handle.

Selecting the appropriate series depends on the geometry of the sample and the level of spatial resolution required, since small features and multilayer coatings place greater demands on the optical and detector configuration.

The design rationale behind the platform is to balance measurement speed with data quality. Non-destructive testing protects the surface of the part, so finished goods and precision electronic components can be examined and then returned to production rather than scrapped.

Rugged hardware combined with the WinFTM software suite is intended to lower the operating barrier for non-specialist staff while raising inspection throughput. For manufacturers, the practical outcome is a stream of measurement data that can be used to refine process costs and improve product yield rates.

Such data is most useful when it is collected consistently over time, allowing operators to detect drift in a plating bath, a deposition process or an alloy melt before out-of-specification parts accumulate.
