November 10th, 2026 - By: Gregory Haley Key Takeaways: Chips that pass identical tests can carry very different reliability risks, because marginal behavior often hides inside specification limits. Device-level models, cross-insertion data, and physical inspection can flag suspicious passing parts, but an anomaly isn’t proof of a defect.\n\nReporting also notes that extra screening pays off only when the added test can expose the suspected weakness at a lower cost than the failures it may prevent. A chip passes wafer sort, moves through assembly, and passes final test. Nothing in its results gives anyone a reason to hold it. Yet another chip with nearly identical results could fail in the field because of a weakness neither test exposed, whether that’s a thin timing margin, a slight resistance shift, or a combination of measurements that looks harmless when each is viewed alone.\n\nPoints still worth watching: The challenge for manufacturers is figuring out which of those passing chips deserve another look without retesting everything.
