ISSUES WITH COTS AS SEEN BY INTEGRA TECHNOLOGIES USING LATEST SCREENING
By Sultan Lilani, Director, Integra Technologies - Integra Technologies, through its decades of screening and qualification of thousands of microelectronics, has seen the quality and reliability of COTs significantly improve over the last few years; specially some manufacturers in commercial industry have developed rigorous process controls driven by advanced technologies and commercial market, often equivalent to or exceeding MIL‐SPEC parts. Still, there are concerns with COTS parts used in Military or Space applications depending upon the type of part, application and manufacturer used. The article provides insights on usage of COTS based on Integra collected infant mortality data on 1,438,263 devices from hundreds of various unique lots from most manufacturers and over 200 pin/package combinations during the period of January 2017 through July 2023.
SEMICONDUCTORS IN SPACE
Part procurement, selection, screening, qualification, and analysis activities for the EEE parts used in space. As EEE parts, even commercial grade, are in in short supply, Integra’s vast experience and capabilities in the area of assembly, screening and qualification is helping its key space and terrestrial customers to keep its supply chain requirements met.
SYSTEM IN A PACKAGE
There are many reasons behind this trend, but we believe the ability to quickly and cost effectively mix technologies is one of the most significant.
As densities and speeds increase we believe that there will be more semiconductors implemented in flip chip packaging.
MODELING FOR BEST RESULTS
To obtain the best results of any simulation model, there is more to modeling than simply throwing loads on a CAD design and solving a detailed model. A good model achieves four key results and these should be considered before pushing the “solve” button in any analysis.
