PCB Design Software: Choosing A Unified Platform for PCB Design Priority
Having the right tool for complicated and intricate tasks facilitates success. Having the wrong tool invites frustration. Rummaging through my tool chest the other day found me selecting the only tool available. Hours into the job with each step a struggle, I considered my hasty choice. It would have been better to spend a little money and order the superior tool. Spending the money for a superior EDA tool facilitates progressive and intelligent

Editing Multiple Components Anywhere in Footprint
Circuit board design has changed a lot over the years, and the way we work with library components has shifted as well. Originally, PCB designers created library components by laying down a sticker or “dolly” on a sheet of mylar on a drafting board. Later on, as designers migrated to CAD tools, the components were built using those same CAD tools. Those first tools didn’t offer much assistance to designers and you had to be really good at

Layer Stackup in Rigid and Rigid-Flex PCBs
Building multilayer PCBs is like building with Legos. The all fit together easily, but you still need to follow directions if you want your design to stay together. Nowadays, only the simplest PCBs use a single layer, or a pair of top and bottom layers. Multilayer PCBs are now the norm rather than the exception, and manufacturers can fabricate PCBs with up to 30 layers. Layer stackup strategies in these boards are important for a number of

Linear Devices in Electronics and How They Affect Your Signals
Many cultures view time as linear or as something that moves along a straight line. The flow of time moves from past to present to future. Other cultures, however, have a different perspective about time. Those see time moving in cycles. History repeats itself and all human events occur in cycles. Linear devices in electronics have nothing to do with how we perceive time, but they do matter for how your circuits perform and how they should be

PCB Design Guide to Controlled Impedance During PCB Routing
In June 1831, Sir James Clark Ross discovered the North Magnetic Pole on the Boothia Peninsula in Northern Canada. While the term “discovery” seems to indicate that the North Magnetic Pole is static, the North and South Magnetic Poles, in fact, move continuously. The Earth’s magnetic field changes over time and as those changes occur, the positions of the poles also shift. Given the rate of movement at 55 km per year, we may have another meaning

Coupled Versus Uncoupled Inductors Procurement: Which is Right for Your Switching Power Supply?
I recently took a deep dive into the various types of topologies surrounding switching power supplies. This article examined the benefits and downfalls of some of the most common topologies and aimed to assist you in the process of choosing how to power your design. The SEPIC topology is a very common switching mode power supply that can operate as both a Buck and a Boost converter. In other words, the SEPIC can act as a step-down (Buck converter

Strong Design Software for Differential Pair Routing
Back when I lived in Portland, I used to commute downtown, typically taking the train to and from work. I was thankful to live in a city with a meticulously timed train system. There must be a valid reason to route train lines as differential pairs because I could always count on the trains being on time. Routing differential pairs on a PCB also requires specific rules and meticulous timing that can only be achieved using the best PCB design

Kick Your EDA Translations to the Curb: Choose Unified Design
Personal computing devices have significantly changed how bills are paid. And it’s getting better as utilities, banks, and medical enterprises get onboard with unified, intuitive user interfaces . Not long ago, moving from writing and mailing checks to using online banking for paying bills was excruciating. All the environments and web pages were slightly different. Even the simple process of paying a bill was inconsistent and there was no

Demonstrations for Multi-Layer Designs: Best Uses for Each Layer
In your career as a PCB designer, you will design a lot of different printed circuit boards to accommodate various design technologies that you’ll be confronted with. To that end, you will use a plethora of circuit boards with all kinds of different sizes, shapes, and layer counts. How you decide to configure your PCB layers and what you put on each layer will, of course, be dictated by what you’re designing. Stripline and microstrip routing will

Simulation Driven Design Can Solve Your PCB’s Signal Problems and More
If you work in the electronics industry or in research, there’s a chance that simulations are a regular part of life. Simpler systems can be designed with intuition and simulated after designs are completed, but more advanced systems running at high frequencies or very high data rates need qualification before and after a PCB layout is complete. Simulation software has to take a more prominent role in PCB design for many advanced systems

Using Kirchhoff’s Law to Determine Sufficient PCB Trace Thickness
For as long as I can remember, I've been a fan of peanut butter. Back in elementary school, my mom limited my peanut butter intake to a thin spread on a slice of bread. This didn’t come close to satisfying my cravings so I’d sneakily add a generous inch of peanut butter on sandwiches without my mom’s knowledge. My peanut butter thickness preference, unfortunately, did not help with PCB trace thickness in earlier days of hardware design. It wasn’t

Schematic Organization: How to Systematically Organize Your Messy Schematic Design
Even as a six-year-old, my son is great at organizing his toys and personal belongings. At that age, I used to chuck all my possessions into a huge storage box. My son, on the other hand, has a knack for orderliness that borders on obsessive. Although his meticulous attention to detail can be mildly frustrating at times, it means that I can always trust him to keep his play area organized. In PCB design, you need to exhibit the same level of

Medical Technology Innovations and the Electronics That Enable Them
Ten years ago, who would have thought one of the world’s largest medical equipment manufacturers, General Electric, would look to exit the industry and sell-off its medical equipment business? It is also a fact of life that changes like these tend to drive companies to look for profit opportunities in other industries. In the 21st century, with a rapidly aging global population, you have the likes of aerospace giants, such as Lockheed-Martin and
