PCB Design

Read the latest information PCB Design from the industry's leading experts.

CS 1.4 has been released - Now easier than ever to migrate from Eagle™ Of particular note in this release, is the addition of Classes. Within the schematic, Net Classes can be generated using the new Net Class directive and Component Classes are automatically generated for each Schematic Sheet within the hierarchy. Within PCB a new Classes dialog is available on the Home tab in the Design Rules section, and this can be used to create Pad, Polygon, Component, Layer, and Net Classes. CircuitStudio® is the world’s Read Article

Need to Keep Your PCB Project Under Budget? Use a PCB Design Tool that Helps You Do That When you design a printed circuit board, you tend to design it for ideal conditions. You figure out how things should work together and engineer a solution that works perfectly on paper. Unfortunately, when you go to manufacture that PCB and apply it for its intended use, you very rarely come across ideal conditions. What works on paper doesn’t always match up with reality. As a result, you often have to do what you can to salvage the design and Read Article

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 freeze 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; they use geometric shapes or heat exchangers Read Article

A Comparison of Active Cooling Techniques for Electronic Equipment Cooling your electronics is pretty important. I know this because part of my laptop’s motherboard melted once. I bought a new top of the line computer back in 2010 to try out a new graphics intensive video game. It came with an amazing graphics card, but an undersized thermal management system. I should have known there was a problem when the keyboard got too hot to touch when I started playing games. Soon afterward, my computer was on the fritz Read Article

How IBM’s 5 nm Transistors Will Enable Internet of Things Deep Learning and Other Technologies My great grandmother was born in a time when normal people still used horses and carriages to get around. By the end of her life, she had seen jet airplanes, computers, and spacecraft. Technology in the last century accelerated rapidly, and this century promises more of the same. Moore’s Law has been one measure of the pace of advancement. While many experts have predicted its doom, Moore’s Law stands today. The most recent proof of electronic Read Article

How to Choose the Right Reflow Oven for Your PCB Whether you’re an electrical engineer or an electronics hobbyist, solder reflow ovens enable fast and convenient printed board (PCB) assembly. If you have assembled dense PCBs with many small surface-mount components or used ball grid array (BGA) devices in your designs, you have undoubtedly come across solder PCB reflow ovens. While the ambitious hobbyist may choose to build a toaster oven “reflow oven”, many businesses can save time and Read Article

How to Setup and Interface with WS2812B LEDs Are you in the mood for a good laugh? Well, I have a story for you. I’m a design engineer with decades of experience, but a LED project recently almost brought me to my knees in despair. I used to think that LEDs were as simple as getting the light emitting diode connected to a limiting resistor and a power supply. Aren’t they? That’s exactly what went through my mind as I worked on an architecture model lighting project a couple of years ago. On Read Article

Intel Will Showcase Future Technology in Electronics and Communication at the Olympics Editorial credit: lazyllama / Shutterstock.com I love watching the Olympics. It’s exciting to see the best athletes from each country test their skills against one another. The Olympics are also a forum for host countries to showcase everything that they’re capable of. In the 2018 Olympics countries aren’t the only ones who will be showing off. Intel recently announced a partnership with the International Olympic Committee (IOC) that will let Read Article

How to Perform In-House Pre-Compliance Testing for Radiated Emissions Sometimes you can feel like you’re putting out good vibes, but you’re really emitting something else. The same goes for wireless circuits. You go through design and immunity testing, then send your board off to an EMC lab only to find out your board is radiating the electronic equivalent of garlic breath. Performing in-house pre-compliance testing can help you avoid a costly rejection. You’ll have to spend some money on equipment, but it will Read Article

Conducted Emissions Test Equipment and Reduction Guidelines One of my classes in college was so difficult that the professor would give us the test questions a week in advance. Even knowing exactly what to study for the exam, lots of students still failed. Conducted emissions analysis for electromagnetic compatibility (EMC) is similar. Devices need to be checked to see if they’re putting too much noise back into the grid through their power supply. Otherwise, the FCC will think you’re disrupting utility Read Article

How FRAM Memory Simplifies Embedded System Data Logging I’ve always found it easier to make decisions when the options were clear cut. Choosing between black or white, right or wrong, you could make your decision and never regret it. However, decisions that involve picking black, white or one of many shades of gray really stress me out. I was happy abiding by my binary logic until Ferromagnetic Random Access Memory (FRAM) came on the commercial market and I was forced to embrace one of the shades of Read Article

Advantages of Massive MIMO for 5G Cellular Infrastructure Editorial credit: PureRadiancePhoto / Shutterstock.com Even though I ended up here in southern California, I was originally born in Texas. We have a saying that you probably have heard, “everything’s bigger in Texas.” That turned out to be true for me, as I’m the tallest member of my extended family. I’d like to think that the minds behind massive multiple input multiple output (MIMO) antenna arrays were also born in Texas. MIMO has been around Read Article

The RS485 Interface in a Wireless World I am a huge fan of the Nokia 3310 that made a comeback in the mobile phone industry a few years ago. If you’ve never used one in your life then you’re missing out on one of the most reliable and durable mobile phone in recent history. Unlike the early 2000’s, it’s not easy to find mobile phones that can double as a hammer or fall into the Grand Canyon and survive. In the world of electrical design, RS485 communication offers a similar robustness Read Article

IoT Storage Technologies: Ultra Low Power CBRAM Do you remember using those old floppy disks back in the day? I remember my computer had two floppy disk drives. You’d put the disk with your program in one and a disk for the data in the other. Eventually, the incredible invention that is the hard drive came about and storage space exploded. Our memory capacity is still increasing, but now size is becoming less of a factor. When it comes to the Internet of Things (IoT) energy usage is the next Read Article

Wearable Technology in the Future 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 electronic devices than clothes, but the line between the two is beginning to Read Article

The IoT is Developing New Technologies for Aging in Place My grandmother has lived down the street from my parents for the past 7 years. She moved down there after it became apparent she had Alzheimer’s disease and my parents realized she couldn’t live alone anymore. However, technology has allowed her to live a semi-independent life. My mother uses nanny cams to make sure my grandma is safe and happy and goes down to the house whenever grandma needs help. This arrangement has kept my grandmother out of Read Article
