Modeling PCBs For Common Causes Of Failure


By Theresa Duncan and Michael Blattau When designing printed circuit boards (PCBs), keep in mind the major causes of electronic failure: thermal cycling, vibration, and mechanical shock and drop. You can perform a variety of physical tests to determine how and why electronics fail, however, a much faster and cost-effective solution is PCB modeling and simulation. When simulation is used i... » read more

Improving Automotive Electronic Hardware With SAE J3168


By Theresa Duncan and Craig Hillman The race is on for fully autonomous vehicles. Industry giants like Tesla, Google, Uber and almost all major automotive companies are competing to deliver state-of-the-art self-driving vehicles. However, the development of new, cutting-edge technologies demands a similar wave of reliability, repairability and warranty standards that automotive manufactur... » read more

10X Faster Electromagnetic 3D Simulation


Virtual prototypes are essential to optimize the signal integrity performance of their high-performance electronics products. Today, engineering teams are pushing to get fast electromagnetic (EM) simulations of printed circuit boards (PCB) and 3D chip packages in just a few hours with the highest level of accuracy. The state of the art in EM simulation has come a long way: Back in 2000 it wa... » read more

Simulating The Hyperloop


When SpaceX held the first Hyperloop Design Weekend Competition in Texas in January 2016, a team of five students from the Universitat Politècnica de València (UPV) in Spain, calling themselves Hyperloop UPV, won awards for Best Overall Concept Design and Best Propulsion System. The overall concept was to use magnetic levitation to give their Hyperloop vehicle a frictionless ride through t... » read more

Elasticity Without Compromise


At the dawn of the twenty-first century, the available RAM on a physical machine dictated, and ultimately limited, the size of designs that Ansys HFSS could simulate. This prompted engineers to buy incredibly expensive pieces of hardware — well into the six figures — to solve their most challenging problems. By necessity, engineers learned to “divide and conquer” their largest, most ... » read more

Design For Manufacturing Best Practices


Manufacturing issues are one of the top reasons that we see warranty returns and loss of market share in the electronics industry. Issues like supply chain failures and printed circuit board assembly (PCBA) production challenges related to design can lead to irreparable damage to a brand’s reputation. It is therefore critical that companies have a design for manufacturability (DfM) protocol i... » read more

Simulate Automotive Radar In 5 Dimensions


Automotive radar has emerged as one of the backbone technologies in the automotive industry’s advanced driver assistance systems (ADAS) revolution. Because radar uses electromagnetic waves to sense the environment, it can operate over a long distance in poor visibility or inclement weather conditions. Designing automotive radar that accurately captures diverse traffic situations will be essen... » read more
