How Do the Seamless Transfer and Use of PCB Design Data Improve Workflows? How Do the Seamless Transfer and Use of PCB Design Data Improve Workflows? Introduction One of the more thrilling events in track and field is the 400 Meter relay race. Understand, I don’t run; rather I enjoy watching. However, the most critical part of every race is the transferring of the baton to the next runner. I was watching a race some time back where one team was way ahead of the others and was coming around the final turn for the last hand-off. But, THEY DROPPED THE BATON, and they ended up losing.

PCB Design - It is a Team Sport PCB Design - It is a Team Sport Introduction A poem by John Donne is the source of a phrase we are all familiar with: “No man is an island.” Although he was speaking of how human beings do rather poorly when isolated from others and need to be part of a community to thrive, this principle is especially true when it comes to the PCB Design process. That no single person—or better said, roles—are involved in the PCB design. I would contend that for any PCB Design to be a success Read Article
Solving Component Library Errors During PCB Layout Reuse Solving Component Library Errors During PCB Layout Reuse With the right PCB design package, you can even reuse layouts for these old cell phones I recently bought a new computer after data on my old hard drive started to “magically” become corrupted. Once I broke into my new computer and transferred my data over, I became worried I wouldn’t be able to reuse my old data. When it comes to simpler things like text files or images, you’ll have no problems; you can immediately reopen and reuse these files Read Article
77 GHz Radar for Automotive PCBs: Routing and Signal Integrity 77 GHz Radar for Automotive Radar PCBs: Routing and Signal Integrity Technology moves quickly these days, and automotive radar has transferred from primarily operating near a 24 GHz to a 77 GHz wavelength shortly after its introduction into new vehicles for object detection. Recent regulation changes have allowed the transition to 77 GHz, which provides a number of benefits. Shorter wavelengths facilitate wider bandwidths, and provide better resolution, smaller device form factors, and longer range. This band just Read Article
Automotive Telematics System Design Automotive Telematics Systems Design In 2015, the cost of the electronics in a new car surpassed the cost of raw steel for the first time in history. We shouldn’t be surprised; the increasing number of electronic systems placed in cars over time made this change in cost structure inevitable. As cars become more autonomous, more connected, and include more creature comforts, this trend is only going to continue. After the OnStar system was popularized by General Motors in the 1990s Read Article
Relative Permittivity of PCB Substrates: High-k or low-k dielectrics? Relative Permittivity of PCB Substrates: High-k or low-k dielectrics? The relative permittivity of water makes this pencil appear bent If you’ve paid attention to refraction, then you know something about the physics of relative permittivity. The semiconductor industry has managed to continue scaling to smaller technology nodes by using materials with high dielectric constant (so-called high-k dielectrics), but can you see similar benefits in your PCB with similar substrate materials? What about the use of low-k Read Article
Advanced Electronics: Understanding Design Challenges for Space Applications Part 1 Advanced Electronics: Understanding Design Challenges for Space Applications Part 1 Electronics design for space applications is a subject I’ve always been passionate about, and understanding the reasons particles can damage circuitry has always fascinated me. In this article, we’ll discuss how a Beta or Gamma particle can create—for a short period of time (usually referred as SEE or Single Event Effect)—a large current in your design which could lead to permanent damage if ignored. We’ll discuss a technique I have used in my Read Article

ECAD-MCAD Collaboration - Bridging the Communication Gap ECAD-MCAD Collaboration - Bridging the Communication Gap Let’s face it, there are things that we do the same way every day, simply because ‘we have always done them that way’ and we are used to them. Due to schedule pressures and outside demands, there is rarely time to think about how to make these things better, never mind try to actually implement something new. This makes the motivation to invest in exploring different methodologies challenging. Our general tendencies lean more toward continuing to Read Article
How does Altium Designer improve PCB design workflows? How Does Altium Designer Improve PCB Design Workflows? One of the great pleasures in my life is to be the grandfather of—as of now—five grandkids. It’s interesting to watch them go through various stages of learning. There is Caleb, who is four, and Ashley, who is five (though she loves to remind everyone that she is NOT five, but five and seven months). Both are in different stages of learning. Ashley’s question for everything is “WHAT”, and Caleb, his question is “WHY.” What are we doing? Why is Read Article
