Cost Impacts of Upgrading Electronic Parts

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…

Computerized Simulation Tools Are Used

An integrated circuit or monolithic integrated circuit (also referred to as an ic, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or “Chip”) of semiconductor material, normally silicon. The integration of large numbers of tiny transistors into a small chip resulted in circuits that are orders of…
