Fake electronic components pose a risk to the industry and were found in US military equipment. A high resolution microscope can be used to detect fake components by examining features like lead arrangement, ball height, markings, and for signs they were sanded, like small holes from re-engraving laser markings. Using multiple testing methods, like a high resolution microscope, X-ray, and chemical analysis, allows a supplier to thoroughly check components for authenticity. Companies risk financial loss and damage to their reputation if fake components enter their supply chain.
