Detection of Counterfeit Components by K-Shell XRF Technique
Counterfeit components are a major issue facing the electronic industry. The counterfeit suppliers are getting more sophisticated and are employing techniques such as laser etching in production of these components which makes them virtually undetectable from the real parts.
In the majority of cases, these counterfeit parts do not contain expensive elements such as gold (Au), bismuth (Bi), tantalum (Ta), silver (Ag), etc. Instead they are often substituting the costly materials with lead (Pb), palladium (Pd), or other low cost elements.
The K-Shell XRF systems, due to their penetrating feature, are capable of providing qualitative data for the presence or absence of substances through components and packaging without needing to disturb the actual component or the packaging materials. |
