An educational resource about counterfeit electronic components: what they are, how they enter supply chains, and how they are detected.https://cilm.tech/https://cilm.tech/pillar/detection-methods-and-their-limits/https://cilm.tech/pillar/detection-methods-and-their-limits/What documentary, physical, and analytical methods for evaluating suspect electronic components can establish, and why no result proves authenticity.https://cilm.tech/pillar/lot-level-verification/https://cilm.tech/pillar/lot-level-verification/How CILM selects verification depth for a specific procurement lot, using a four-level L0-L3 scale of progressively deeper evidence.https://cilm.tech/pillar/measuring-supply-chain-risk/https://cilm.tech/pillar/measuring-supply-chain-risk/Why assessing a component or supplier is not the same as assessing a specific lot, and how CILM measures risk as evidence sufficiency.https://cilm.tech/pillar/procurement-channels/https://cilm.tech/pillar/procurement-channels/How the route from manufacturer to buyer shapes the evidence available for a lot: authorized, independent, and open-market channels.https://cilm.tech/pillar/standards-landscape/https://cilm.tech/pillar/standards-landscape/The established standards that govern counterfeit-part avoidance, testing, and distribution, and where CILM sits in relation to them.https://cilm.tech/pillar/the-evidence-base/https://cilm.tech/pillar/the-evidence-base/An open, anonymised corpus of real pre-purchase procurement communications, published on IEEE DataPort, and the research question it opens.https://cilm.tech/pillar/what-counterfeit-electronic-components-are/https://cilm.tech/pillar/what-counterfeit-electronic-components-are/Counterfeit and nonconforming electronic components: an ordered inspection sequence and a working taxonomy for identifying each type.https://cilm.tech/pillar/what-counterfeit-electronic-components-cost/https://cilm.tech/pillar/what-counterfeit-electronic-components-cost/The cost of counterfeit electronic components is not a single number. It accumulates across evidence uncertainty, verification, and rework.https://cilm.tech/pillar/why-supplier-qualification-is-not-enough/https://cilm.tech/pillar/why-supplier-qualification-is-not-enough/Supplier qualification decides who may supply; it does not verify what is in a given lot. Why component integrity is a per-delivery question.https://cilm.tech/methodology-status/https://cilm.tech/methodology-status/Where CILM stands today: what has been observed in a pilot window, what remains to be validated, and what is deliberately not yet published.
