Coping With Parallel Test Site-to-Site Variation


Testing multiple devices in parallel using the same ATE results in reduced test time and lower costs, but it requires engineering finesse to make it so. Minimizing test measurement variation for each device under test (DUT) is a multi-physics problem, and it's one that is becoming more essential to resolve at each new process node and in multi-chip packages. It requires synchronization of el... » read more

RF/Microwave Technology Driving The Connected Car


In-car networks and advanced driver-assistance systems (ADAS), made possible through wireless sensors, driver-assist radar, vehicle communications, and related electronics, present many design challenges to engineers. Simulation software enables design teams to effectively manage the complex design and integration challenges associated with developing these high-speed and RF-enabled networks. T... » read more

3D Printing For More Circuits


After several years of experimentation, and growing success in volume manufacturing for some use cases, technologies for 3D printing of electronic circuits are becoming more common. Some innovations in processes and materials are moving these technologies closer to mainstream electronics manufacturing. Christopher Tuck, professor of material science at the University of Nottingham, observed ... » read more

Challenges In RF Design


Designing highly integrated components for radio frequency applications poses special challenges for system engineers, designers and the commissioning engineers. The boundary between chip, package and board is increasingly vanishing on modern components. It is growing more common for parts of the functionality to be moved to the package or even the board. In some cases, the requirements have be... » read more

System-In-Package Thrives In The Shadows


IC packaging continues to play a big role in the development of new electronic products, particularly with system-in-package (SiP), a successful approach that continues to gain momentum — but mostly under the radar because it adds a competitive edge. With a SiP, several chips and other components are integrated into a package, enabling it to function as an electronic system or sub-system. ... » read more

Specialty Technologies Bring New Functionality


As a materials engineer, I am very proud of the fact that key advances in human civilization have been driven by materials innovation. The stone age, bronze age, and iron age were all essential steps in setting the human race on the path that we are on today. Innovations are not without their downsides, but they have enabled progress in agriculture, medicine, transportation, communication, a... » read more

Empowering RF Front End Cellular Innovations With DSMBGA


With the introduction of 5G, cellular frequency bands have increased considerably, requiring innovative solutions for the packaging of RF front-end modules for smartphones and other 5G-enabled devices. Double-sided, molded ball grid array (DSMBGA) is a prime example of such solutions. “With our DSMBGA platform, we’ve established a preferred advanced packaging solution for this domain,”... » read more

Wafer-Level Fan-Out For High-Performance, Low-Cost Packaging Of Monolithic RF MEMS/CMOS


Navigating the trade-offs between performance, size, cost and reliability can be a challenge when considering integrated circuit (IC) packaging and the end-application. The integration of micro-electromechanical systems (MEMS), either monolithic or heterogeneous, introduces yet another level of complexity that has only recently been a major focus of multi-device packaging [1]. Wafer-level fanou... » read more

Electrically connected spin-torque oscillators array for 2.4 GHz WiFi band transmission and energy harvesting


Researchers at the National University of Singapore and Tohoku University developed a device that uses spin-torque oscillators (STOs) to harvest energy from 2.4GHz Wi-Fi signals and wirelessly power an LED without need for a battery.   Technical Paper Link: Abstract "The mutual synchronization of spin-torque oscillators (STOs) is critical for communication, energy harvesting ... » read more
