Everything You Need to Know About Microvias in Printed Circuit Design
Have you ever wondered how designers pack so much functionality into such a small space? You can thank HDI design techniques and microvias in printed circuit design. These small structures let traces reach inner layers of a PCB with high interconnect density and high layer count. These structures have been around for years, but they are becoming more common in a variety of systems that require multiple functions on a single circuit board. If you

Overcoming the Challenges with Rigid Flex Design
There is no question that wearable electronic devices qualify as “break-out products”. The market for wearables is forecasted to be $30 billion in 2016 and will grow to $150 billion by 2026[1]. Most of these devices are simply impossible without rigid-flex PCB design technology. This means that engineers and PCB designers need to become experts in designing, testing, and manufacturing in a wearable and “foldable” world. The most familiar products

The Pros and Cons of Different LPWAN Networks for Your IoT Application
Right now, IoT is like a gladiator battle in the coliseum of market forces and public opinion. There are constant rankings of what protocol or stack to use, which IoT products are useful ( or not), and who’s going to win each element of the burgeoning IoT ecosystem. The best part is that each of these little battles is also a decision that you must face or plan for in your next IoT design. Awesome, right? Lucky for you, I’ve already considered

Design Release Management and Communicating Intent
We know that designing and releasing a product involves a multidisciplinary chain of command. Prior to its release, the ECAD side often goes through a series of adaptations to capture the incremental changes to the design. During this stage, the ECAD data is a moving target, which can impede the flow of communication to invested parties. Failure to effectively communicate these changes can have significant consequences on the design release

How to Design MicroSD Card Power Circuits Without Destabilizing the On-Board Voltage Supply
PCB designers often have the tough job of balancing perfection in design and keeping the cost down. For designs dealing with storage medias, like microSD, neglecting simple terms like “hot insertion” or “inrush current” can result in a prototype that imperfect and costly. My philosophy is to keep my hardware designs simple. I am quick to discard any components that seem superficial in my design. Unfortunately, I learned the hard way that keeping

PCB Design Guidelines for High-Frequency Circuits in Car Radar & 5G Applications
One of the latest evolutions in next generation of 5G PCB design guidelines is being driven by two emerging technologies, 5G networks and advanced driver assistance system (ADAS) enabled cars. Both of these technologies use something long feared by PCB designers, the extremely high-frequency (EHF) band. Read on and prepare your boards for a high-frequency future. This morning I saw a very strange sight while walking down my street. A long

Best Practices for High-Frequency PCB Materials Selection
High frequency PCB design can seem esoteric, and I've heard many an engineer describe it as "black magic"! The subject is also a bit confusing, especially once someone asks which frequencies could be reasonably considered "high". The reality is that some of the challenges present in high speed design also appear in high frequency design, but we think about them in different ways. Before you do anything inside the layout for a high-speed or RF PCB

Why Would Anyone Migrate from Mentor Xpedition Enterprise to Altium Designer?
Many users of Xpedition Enterprise didn’t choose it: it was inherited in an acquisition or packaged in a bundle with other products. Now they find they have expensive support costs and many features that they never use. Plus, the tool UI are old and tired, making design more time consuming than it should be. Moving to Altium Designer

Which IoT Communication Protocols Are Best Suited to Your Design Requirements
For IoT products, the interoperability question depends on the communications protocol you use, since most products can’t communicate with systems using a different protocol. The protocol you choose will also affect your hardware. For example, transmission distance will determine your available IoT modules, power requirements, and shape the network configuration for your system. There are a huge number of protocols to choose from. New versions

FIRST Robotics Competition Makes STEM Students into Superstars
Over 25 years ago, FIRST Robotics Competition (FRC) founder and prolific inventor, Dean Kamen, envisioned a high school robotics competition that rivaled the energy and excitement of the Super Bowl. An event that would turn science students into superstars and infect them with an unshakeable passion for STEM activities and careers. Chris Jennings has an infectious enthusiasm for the FIRST Robotics Competition (FRC), as well as a rich history with

How Low Power Wide Area Networks Are Enabling IoT Systems
LPWANs can enable something like a “smart” city. What do civil engineers love, but electrical engineers hate? Concrete. This thing that makes up the base of our physical world often confounds the electrical signals that are the foundation of our digital world. Parking decks, malls, and underground structures all suffer from bad signal coverage. Without some kind of window or repeater, you’ll rarely get good coverage in these areas. That’s

Over-The-Air Connectivity Means Quick Updates, but New Security Challenges
Thanks to the accelerating pace vehicle systems are being computerized, updating and securing control firmware is a new responsibility for automotive manufacturers. Over-the-air connectivity means crucial patches, especially those closing security holes, can be silently pushed to thousands of cars without user intervention. That said, it’s important to realize that an over-the-air solution presents a double-edged sword: if not implemented
