TECHNIQUES FOR SUSPECT/COUNTERFEIT EEE PARTS BY X-RAY FLUORESCENCE TEST METHODS
XRF technique for counterfeit detection is applicable to electronic and other parts as listed in the AS6171 General Requirements. In general, the detection technique is meant for use on piece parts prior to assembly on a circuit board or on the parts that are removed from a circuit board. The applicability spans a large swath of active, passive and electromechanical parts.
Since counterfeit electronics components are likely to have some level of material difference from the genuine components, techniques that identify the chemical elements in different areas of a part are essential to benchmarking authentic parts and comparing them to parts under consideration. X-ray fluorescence (XRF) is one such technique that can be applied both to the external surfaces and internal elements of a part. The method itself is non-destructive by nature.
