Don't do a spit-take with your coffee - there is no double-sided BGA. It would never see the light of day, simply because no one would ever buy it. Sure the density is unbeatable, but there is no practical method of soldering all the leads on such a package to a printed circuit board. No electrical hardware design engineer would accept such a ridiculous package. Then why do … [Read more...]
Thermal Issues in GaAs Analog RF Devices
Wireless communication and advanced radar systems require circuitry that can operate at frequencies greater than 2 GHz and at high power levels. Analog gallium arsenide (GaAs) semiconductors are frequently used in these applications and present additional challenges for thermal engineers compared to silicon semiconductors. Whereas thermal characterization modeling and … [Read more...]
Advanced Techniques for IC Surface Temperature Measurement
Introduction: The Need for IC Surface Measurement Techniques Current trends in microelectronic design generate challenges in both the design and test of integrated circuits (ICs). One area that has been gaining increased relevance with regard to the microelectronic evolution is thermal management/analysis, which proves essential in the domain of IC design to prevent reliability … [Read more...]
Noise emission of telecommunication devices
Modern environmental requirements demand low noise levels for telecommunication cabinet products, especially when located in offices or urban areas. The spaces available are limited, and the power and electronics packaging density are increasing. Fans are commonly used to enhance the cooling of electronics by improving heat transfer due to higher air velocities. In this paper, … [Read more...]
Temperature and reliability in electronics systems – the missing link
To introduce the reliability requirements we face for the future, we focus on telecommunication as an example. Personal telecommunication is becoming increasingly integrated into our daily lives. However, we cannot take full advantage of the technology unless the telecommunication system is as dependable as a car. Just as turning the ignition key should produce the right engine … [Read more...]
