Abstract: Various reliability testing standards like JEDEC/AED/MIL/IEC etc. are commonly used in the semi-conductor and consumer electronics for reliability qualification of IC components and consumer electronics devices. However, “blanket” qualification criteria that are not based on knowledge of customers’ usage behaviors and physics of failure expose the manufacturers to two risks. At one end of the spectrum lies the risk of over-design and added cost while on the other end lie the risks of field failures, warranty costs, negative user experience and erosion of the corporation’s brand. The present talk will draw upon examples from semi-conductor chip/package and consumer electronics to compare qualification criteria based on standards to those based upon product use conditions. Widely prevalent failure modes like moisture diffusion in polymers and fatigue of solders will be invoked to make quantitative comparisons between standards and use conditions based reliability qualification criteria. The talk will take a critical look at JEDEC criteria for temperature-humidity, thermal cycling and bake testing.
