Looking Back at Board Test


Printed circuit board testing has been around as long as printed circuit boards, also known as printed circuit assemblies and printed wiring boards. PCB technology started in the early 20th century with Thomas Edison and other inventors. As boards shrink to fit inside wearable gadgets and other products with compact form factors, PCB test equipment vendors are addressing new challenges. Boar... » read more

7 Design Aspects of IoT PCB Designs


To consumers, IoT devices look sleek and simple, but they are comprised of a distinct set of components, physical interfaces, PCBs, and circuitry that presents unique design and layout challenges. This paper looks at seven things to consider when designing PCBs for successful IoT devices. To read more, click here. » read more

Electrothermal Mechanical Stress Reference Design Flow For Printed Circuit Boards And Electronic Packages


This paper presents a reference design flow for solving the electrical, thermal and mechanical challenges of a printed circuit board (PCB) using simulation tools from ANSYS. This approach can be utilized for all electrical CAD (ECAD) types such as IC packages, touch panel displays, and glass and silicon interposers. The authors followed this reference design flow for analyzing a PCB virtual pro... » read more

Chip-Package-Board Issues Grow


As systems migrate from a single die in a single package on a board, to multiple dies with multiple packaging options and multiple PCB form factors, it is becoming critical to move system planning, assembly, and optimization much earlier in the design-through-manufacturing flow. This is easier said than done. Multiple tools and operating systems are now used at each phase of the flow, partic... » read more

What’s Missing In Advanced Packaging


Even though Moore's Law is running out of steam, there is still a need to increase functional density. Increasingly, this is being done with heterogeneous integration at the package or module level. This is proving harder than it looks. At this point there are no standardized methodologies, and tools often are retrofitted versions of existing tools that don't take into account the challenges... » read more

7nm Design Success Starts With Multi-Domain Multi-Physics Analysis


Companies can benefit from advancements in the latest semiconductor process technology by delivering smaller, faster and lower power products, especially for those servicing mobile, high performance computing and automotive ADAS applications. By using 7nm processes, design teams are able to add a lot more functionality onto a single chip and lower the power consumption by scaling operating volt... » read more

Multi-Board System Design


The last decade has seen extraordinary advances in printed circuit board design and fabrication. There has been substantial advances across design, from schematic entry to simulation to layout and routing to team collaboration and even to the way that manufacturing data is transferred to the fabricator. But there is one place where advancement has seemingly been stalled: the overarching system-... » read more

Avoiding The Barriers For Multi-Board Systems Design Development


Designing electronic systems that comprise multiple interacting boards, connectors and cables requires a multi-discipline team collaboration to effectively manage design complexity for optimum product performance and reliability. Multi-board systems may comprise two boards or up to hundreds of boards, packing a cabinet or rack, with interconnected connectors and/or cables. Since the hardware fu... » read more

Partitioning For Power


Examine any smartphone design today and most of the electronic circuitry is "off" most of the time. And regardless of how many processor cores are available, it's rare to use more than a couple of those cores at any point in time. The emphasis is shifting, though, as the mobility market flattens and other markets such as driver-assisted vehicles and IoT begin gaining traction. In a car, turn... » read more

Electronic Design Creation: Overcoming PCB Design Challenges


Think of all the parts that make up the human body: legs, hands, lungs, bones, muscles, and so forth. Yet we are more than mere parts and organs, more than materials and functions. We are human beings. If one part doesn’t work smoothly, all parts are affected. This paper describes how the principle of 'gestalt,' in which an entity is more than the sum of its parts, pertains to the process of ... » read more
