90 SMT007 MAGAZINE I JANUARY 2022 We introduce a novel method that allows checking the components visually and evalu- ates their compliance 4 . e inspection utiliz- es the vision system that is already operating in the pick-and-place mounting machines to obtain the images of the components right af- ter the pick-up and before placement without causing delays or adding additional production stages. e images are processed on the fly by a series of artificial intelligence algorithms capa- ble of authenticating the manufacturer, deter- mining the conditions of the soldering leads, finding defects, and evidence of unauthorized programming. Conventional Mitigation Taping of counterfeit components today is designed to avoid detection by sampling. An example can be seen in Figure 1, where produc- tion images taken by the pick-and-place ma- chine vision system (ASM's Siplace SX), and extracted by Cybord's SMT soware, shows that the beginning of the reel is authenticated to the documented manufacturer (Taiyo Yuden, in this example) and the rest of the components on the reel are manufactured by an unknown source (counterfeit) as also exemplified by the example images and the measured dimensions. Another example of a mixed reel can be seen in Figure 2, where four groups of components were found on a single reel during production. In this case, the different sources are mixed within the reel uniformly. Authentic components that were badly han- dled have no record of that. ey may infiltrate production. ey cause solderability issues during assembly and reliability issues during the product life cycle 1 . An example can be seen in Figure 3 for components with poor quality of soldering leads with forged date codes. Inspecting the entire reel is essential for meeting reliability expectations, but lab in- spection services cannot scale efficiently to support this requirement 4 . e digital trans- formation of the electronic component inspec- tion process removes the dependence on hu- man judgment and demanding labor. e pat- ented 5,6 soware visually inspects and detects suspect and fraudulent components, achieving 100% component inspection coverage. Figure 1: An example of a reel comprising concatenated sources. The spiral on the bottom represents the position on the reel where each color stands for a different detected group. The outer shell of the reel is detected as 0603 MLCC made by Taiyo Yuden and the internal group is of an unknown source.
