The Empirical Baseline

Tech Insights is SCITEO's official engineering literature, built on two foundations: the reliability baselines of GJB 150A, JEDEC JESD22-A101 and AEC-Q100, and first-party engineering test data. It decodes the physics of failure, the selection logic and the process windows behind high- and low-temperature, thermally conductive, conductive and aging-resistant adhesives, and the semiconductor packaging materials they hold together. The scope runs from AI processors and power semiconductors to sensors and defense components. Traceable, hard-science reference, from the engineering think tank.
