Peeling Away Memory Chips
Stefan Behler, Besi, Switzerland
As memory chips become smaller and smaller, designers must ensure that the chips stay intact during the manufacturing process. Besi develops equipment and assembly processes for substrate and wafer packaging production in markets such as consumer electronics, automotive, industrial, and solar energy. Stefan Behler, a senior expert process engineer, used multiphysics simulation to explore and ...
Innovative Motor Designs for Electric Cars Come to Life
Omar Laldin, Faraday Future, USA
If electric vehicles are to ultimately transcend from niche to mainstream, their motor designs must continually progress. Modern improvements in electric vehicle motors, known as power magnetic devices (PMDs), come in the form of simultaneous increases in power capability and manufacturability and decreases in size and cost. Faraday Future, a company that develops intelligent electric vehicles, ...
Analyzing the LHC Magnet Quenches
Lorenzo Bortot, CERN, Switzerland
Engineers and physicists at CERN go to great lengths to ensure that the high-power superconducting magnets that maintain the circular trajectory of particles inside the Large Hadron Collider (LHC) do not revert to a resistive state, an event known as a quench. To understand and prevent quench events, Lorenzo Bortot, an electrical engineer and research fellow at CERN, used numerical simulation to ...
Fuel Cells Poised to Replace India’s Diesel Generators
Ashish Lele, National Chemical Laboratory, India
Inefficient and potentially harmful diesel generators are still the prevailing method of decentralized power generation for telecommunications in urban and rural India. Researchers at the National Chemical Laboratory are investigating proton exchange membrane (PEM) fuel cells, which are strong candidates for this industry because of their cleanliness, compatibility, and efficiency exceeding 30% ...
Simulation Apps Bring STEM to Life
Ivana Milanovic, University of Hartford, USA
While covering the required fundamental material in undergraduate academic programs is the top priority, students require an extra set of knowledge and skills to flourish in the workforce. This is especially true in science, technology, engineering, and mathematics (STEM) fields, where there is rarely an abundance of time for inquiry-based learning and the development of field-specific skills. ...
A New Route to High Sensitivity Pressure Sensors
Jonas Osório, Cristiano Cordeiro, Unicamp; Marcos Franco, Valdir Serrão, Instituto de Estudos Avançados, Brazil
The environments in which sensors are most integral are often the most harsh and unforgiving, such as vacuum chambers, the ocean floor, and petroleum reservoirs. Traditional sensing techniques are not ideal in these applications, whereas optical fiber sensors can provide a versatile pressure sensing solution, as they are sensitive and electromagnetically immune. Researchers at Universidade ...
MTC Develops Simulation App to Revolutionize Design for Additively Manufactured Parts
Borja Lazaro Toralles, Manufacturing Technology Centre, UK
Tolerances and precision in the aerospace industry are astoundingly tight. Because of the high degree of regulation and safety required, errors and deformation from thermal cycling that occur on the micron scale during manufacturing processes can render a part unusable. Manufacturing Technology Centre (MTC), a company that researches and employs additive manufacturing, is working to optimize the ...
Invisible Connections Will Unveil our 5G Future
Eric Gebhard, Bill Rosas, Signal Microwave, USA
The impending evolution of ultrafast 5G networks from concept to reality will entail significant effort into the complex maintenance of impedance and the precision of individual components at high data transfer rates. Connectors, parts that join electrical transmission lines and transfer electromagnetic energy, must remain electrically neutral and have their impedance matched to the transmission ...
Optimizing Screen Protection During the Manufacturing Process
Frank Hong, Kornerstone Materials Technology (KMTC), China
Cover glass, the screen surface material used for tablets and cell phones, offers exceptional smoothness, a mark-free surface, high visible light transmittance, and protection. The caveat is the glass' arduous manufacturing process and complicated behavior under different conditions. To optimize these processes for mass production, engineers at Kornerstone Materials Technology (KMTC), a display ...
It’s a Bird, It’s a Plane: Flow Patterns around an Oscillating Piezoelectric Fan Blade
Akshat Agarwal, Nokia Bell Labs, Ireland
As electronics grow smaller and smaller and are used for extensive periods of time, their internal heat loads are greater and demand new compact cooling methods. Piezoelectric fans, a stepping stone between natural and forced convection, are one attractive option due to their low energy requirements. Engineers at Nokia Bell Labs are using multiphysics simulation to capture the interplay between ...
