The use of post-procurement processing to increase part reliability assurance, or “upgrading”, is driven by the need for state-of-the-art parts with short lead times. Upgrading is costly. Upgrading should only be done when lead-time and functionalit preclude buying the “Level-ready” equivalent. Cost benefits typically associated with COTS can only be realized if they do not…

An Electronic component becomes obsolete when it is no longer available from the original manufacturer to the original specification. This is the reason why obsolescence management is now an essential part of the product support activities in sectors such as defense, aerospace, nuclear and railway; where systems need to be supported for several decades. If…

Microwaves are electromagnetic radiation in the band of the electromagnetic spectrum with wave length between the upper ranges of radio waves and infrared radiation. Although we tend to see them as separate from radio waves, microwaves are in UHF and EHF range of radio spectrum, however, presenting the specific characteristics due to their high…

The integrated circuit chip is too small and delicate to be handled directly. Each chip is bonded to a set of tiny gold or aluminum wires and set into a flat block of plastic or ceramic. The block has metal pins on the outside, leading to the wires inside. The pins form a solid mechanical…

Integrated circuits are made of semiconducting materials, which are midway between good conductors, like copper, and insulators such as plastic. Silicon is the current favorite. Ultrapure silicon is mixed with small, precise amounts of other elements to create electronic materials with different characteristics. Every electronic appliance we use in our day-to-day life,such as mobile phones,…
