Universal Language: PCB Design to Minimize EMI in Communications Systems

Universal Language: PCB Design to Minimize EMI in Communications Systems Can you imagine what a world without lines would be like? At first, it seems wonderful to not have to wait around anymore, trusting that people will figure their business out. Disneyland, happiest place on Earth, receives about 44,000 people per day. Imagine a thousand people all rushing to get on the next available log flume. No longer just a tower of terror, but a whole theme park. When designing PCBs, your traces are the lines and each has a Read Article

Be the Expert When it Comes to Designing Your Power Distribution PCB

Be the Expert When it Comes to Designing Your Power Distribution PCB Editorial credit: Paolo Bona / Shutterstock.com Around my house, we seem to undergo a transformation to obscure-sport experts every four years, and coincidentally it occurs at the same time that the Winter Olympics is taking place. Yes, I’m talking about the sport of curling. We have all become subject matter experts in the “button,” the “hammer,” the “house,” “sweeping,” and of course the “curl.” Rest assured, by next month we will have Read Article

For Your DC Power Application, Which Switching Power Supply Topology is Right?

For Your DC Power Application, Which Switching Power Supply Topology is Right? We often have our old-timer pioneers to thank for laying down the groundwork for our continued success and future growth. These old-school designers had nothing more than theory and confidence to drive their designs, or more specifically, to drive their failures. But as stated by a multitude of wise individuals, each failure is nothing more than a discovery of how not to do something. However, with the discoveries of failures also come Read Article

Practice Makes Perfect: How to Test Electronic Components during PCB Design

Practice Makes Perfect: Testing and Verifying Electronic Component Assemblies during PCB Design When I was younger, well much younger, I had dreams of one day being a pro athlete. I wanted to be the guy who scored the winning touchdown, knocked in the winning run or hit the buzzer-beater. Although I never made to the professional level, I did have some success and I learned a lot. The most important thing was the results you achieved were strictly tied to your preparation. In other words, if I wanted to do well in the game I had to test Read Article

High Current PCB Design and its Real World Applications

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 Read Article

Designing Your PDN to Work Within Your PCB Layout Guidelines

Designing Your PDN to Work Within Your PCB Layout Guidelines I enjoy watching the occasional episode of Star Trek here and there, and I get a kick out of noting the inconsistencies in their technology. In one episode they may be firing all of their energy weapons at the bad guys, moving at warp 3-billion to time travel and showing no regard as to where their power was coming from. In the next episode though, someone will plug in a space toaster to warm up their breakfast in the galley, and the whole ship Read Article

See Where You are Going with Your PCB Power Distribution Network Design

Electric Distribution Systems and PCBs: Power Distribution Network Design For those of you who have only experienced the brilliant high power of LED, Xenon, or Halogen headlights in today’s modern cars, you may not realize how fortunate you are. My first car was old enough that its headlights could have been candles. One year I received Halogen fog lights for my birthday, and the difference at night was amazing. Not only could I now see what was next to the car in the dark but the fog lights almost out-distanced the Read Article

Learning Current Density: Don’t Pop the Balloon

Learning Current Density: Don’t Pop the Balloon One area of PCB design that probably does not get the attention that it deserves is current density. Current density in a PCB trace is much like the pressure in a balloon. You want to squeeze as much air into the balloon as you can, but if you put too much: boom! The same is true of PCB traces many times. We want the traces to be as small as possible yet carry the most current possible, and if the trace carries too much: boom! For PCBs, that boom Read Article

Backroads or Highway: Managing PCB Power Distribution with a PDN Analyzer

Backroads or Highway: Managing PCB Power Distribution with a PDN Analyzer Who hasn’t been caught daydreaming out the window, overlooking the lines of cars on the freeway at a standstill, wondering about easier or more effective ways of getting to your job on time? And even then, sometimes the alternate routes aren’t always the fastest—there could be road construction, or an event going on which makes you have to re-route even more. At that point, most tend to throw all hopes for getting to work on time out the window Read Article

Don’t Get Caught Sleeping: Resolve PCB Power Distribution Problems

Don’t Get Caught Sleeping: Resolve Symptoms of Bad PCB Power Distribution in Networks and Designs I’ve got a heating problem at the moment—after 30 years of service to the various owners of this house, my furnace is finally throwing in the towel and no longer providing heat. Unfortunately, this has come at a, let’s say, inopportune time with it hovering just under freezing lately, and with nights being even more frigid. We installed an ad hoc heating system comprised of the gas fireplace and several space heaters; however, this is not a long Read Article

Paint by Numbers: Solder Paste Stencil Design Guidelines To Reduce Shortages

Paint by Numbers: Solder Paste Stencil Design Guidelines To Reduce Shortages I’ve never had much artistic talent, but when I was a kid I loved those paint-by-numbers kits. Up until I saw those I’d only used watercolors, but I was enthralled with the thick, slow flow of the paint. I may also have killed some brain cells from breathing all the fumes. I was completely obsessed with keeping the paint in the lines, so I didn’t use the brush they gave you. Instead, I traced the outlines with a toothpick that had barely been Read Article

10 Symptoms of a Bad PDN

10 Symptoms of a Bad PDN At face value, DC power integrity seems to be a simple enough topic -- you just need to make sure that every component on your PCB has the power (current and voltage) it needs when it needs it. But that’s just on the surface. WHAT IS POWER INTEGRITY? The new reality is a bit more complicated. When you start to work with fine-pitch device packages, the manufacturing constraints and power requirements of said devices are almost completely at odds Read Article
