Rigid-Flex Command Set-up and Layer Stack Design
Once you take that nose dive into PCB design, you start to realize how many of your home electronic devices actually work. From DVD drives to laptop monitors, and just about anything that folds, it is all made possible with rigid-flex PCBs. Rigid-flex PCB design can be a tricky beast depending on the software you’re using to create it, but at the end of the design, your printed circuit board will bend and flex like a gymnast. A rigid-flex PCB, at

IOT Security Modules: Modular Hardware for Software Engineers
From PCB designed in CircuitStudio to Zymbit finished product The Internet of Things - Big Promise or Big Problem? By 2023 the IoT promises to be 50 billion connected devices strong, transacting $8 Trillion of economic value! That’s orders of magnitude bigger and much more complex than anything we have seen before, and current models of development, deployment, device management and IoT security don’t easily translate to this new world disorder

How to Create a PCB Layout from a Schematic in Altium Designer
You’ve done your usual excellent job of putting together the PCB schematic. The circuitry is defined and you are ready to go to PCB layout. But this time it’s a little different. Maybe your regular layout resources aren’t available, or perhaps you want to try to do your first layout yourself. Whatever the reason, you are ready to start working on the board side of PCB design, but you’re not sure how to create it from a PCB schematic in Altium

Design Planning with Differential Pair Routing Software and Directive Symbols
If the components on your PCB are like the organs in your body, then your trace routing between components are like blood vessels. What looks like a complex tangle of copper connections is actually a meticulously designed system that uses well-understood design rules. Your PCB design software can help you maximize your productivity while routing and prevent errors using directive designations. Great PCB design software doesn’t just let you set

High Current Board Design and its Real World Applications
With the rise of PCB applications stretching far and wide, designs are being created for applications that extend past simple signal integrity solutions. Advancements in material technology, PCB manufacturing capabilities, and the rising demand for PCB design is opening up the floor for many industries that otherwise have been dormant in the PCB world. Many limitations that were not present a handful of years ago are beginning to loosen. Of

The Best Tools for Multi-Board PCB Systems Design
They say that time flies when you’re having fun. Maybe that’s why I feel like time slows to a crawl when I’m constructing a multi-board PCB device. Designing even one board can be an agonizing task, what with trying to avoid EMI , ground everything properly , mitigate static discharge , and optimize your routing . Creating a system of PCBs that all fit together physically and electrically sometimes tests the limits of tedium. Lucky for us there

Important Considerations for Pads in PCB Design: Pad Cratering Prevention
Every year after Halloween, my school used to have a pumpkin launch, probably so they could get the pumpkins on sale. Mostly, mechanical engineering students participated, but anyone was allowed to enter and see if they could launch their pumpkin the farthest. Sections of campus were blocked off and your path to class was rerouted if you went at all. Most of the engineers got (or took) the morning off for cheering and jeering. Results were

Cooling Your PCB: Overview of Passive PCB Heat Dissipation Techniques
Have you ever been so hot you thought you might melt like a popsicle? Summer down here in SoCal gets pretty toasty and makes me wish I had a few freezes pops. When I get home from work I love to blast the AC and pretend that I live in an igloo. However, the only thing worse than boiling in the heat is seeing all my money evaporate away in cooling bills. Other people take a different approach to cooling PCBs; they use geometric shapes or heat

Why Wearable Technology is the Future and How It Will Be Seamless and Convenient
When I was younger I was a bit of a nerd, and I guess I still am. The most visible sign of my nerdiness was my fashion sense or lack of it. Tall socks, cargo shorts, and a brown Pacman hoodie that I wore in every season, except summer, made up my daily wardrobe. I was simply more interested in gizmos and gadgets than I was in looking good. I’m still more interested in fashionable electronic devices than clothes, but the line between the two is

How Do Ferrite Beads Work and How Do You Choose the Right One?
Sometimes, I wish I could see electromagnetic waves. It would make detecting EMI much easier. Instead of having to mess around with complicated setups and signal analyzers, I could just look and see what all the fuss is about. While we may not be able to see EMI, we can sometimes hear it when it comes through audio circuits. One possible fix for that kind of interference is a ferrite bead. Unfortunately, ferrite beads (also called a ferrite choke

How Increasing Battery Size Guides the PCB Designs of Apple and GoPro
Sometimes batteries get bigger...by adding more batteries As time goes on, power requirements for connected devices keep increasing. More power means larger batteries, which force PCB designers to use more efficient layouts. Apple’s iPhone 7 and GoPro’s Hero5 give us specific examples of how industry leaders are dealing with increasing iPhone battery sizes in their iPhone PCB layouts. Have you noticed how much more energy it takes to get around

Protect Your PCB Design: How to Avoid Counterfeit Electronic Components
Just like Gucci or Coach handbags, counterfeiting electronic parts is big business overseas and it causes major problems in the printed circuit board component supply chain. Counterfeit electronic components that are sold as genuine can affect everything from your new electronic alarm clock to mission-critical military systems, such as thermal weapons sights, missile guidance systems, and aircraft. Whenever electronic parts are relabeled or

How to Design High-Density PCBs While Managing Buried and Blind Vias
The modern is always being pushed to go smaller and cheaper. Blind and buried vias can help you save space and money on your high density PCB layout (HDI). Blind and buried vias help reduce outer layer usage, leaving more room for SMTs and BGA breakout channels. Read on to find out more! Moore’s Law predicts that the number of transistors in integrated circuits (ICs) will double approximately every two years. This law has held true since 1965
