The concept and implementation of differential impedance are both sometimes misunderstood. In addition, the design of a channel to reach a specific differential impedance is often done in a haphazard way. The very concept of differential impedance is something of a mathematical construct that doesn’t fully capture the behavior of each signal in a differential trace. Keep reading to see a bit more depth on how to design to a differential impedance spec and exactly what it means for your design.

Quite often, a standard assembly drawing is not enough to ensure the quality of a PCB assembly, especially when designing high-density boards. It would also be helpful to include additional detailing for simpler devices. The use of a Draftsman document brings an elegant, yet powerful solution to make these tasks easier.

An effective product lifecycle management (PLM) solution will integrate the tools and processes employed to design, develop and manufacture a new device. This solution goes beyond engineering activities to include the project management, process control, and financial management of the end-to-end business processes. PLM solutions create this collaborative environment where product development can flourish, bringing additional benefits in efficiencies and transparent communications, breaking silos, and speeding up the development process.

With ever increasing speeds in high-speed data systems comes a couple of PCB layout challenges. High-speed busses like DDR, VME, PCIe just to mention a few can all reach data transfer speeds that require strict timing with very tight tolerances, thereby leaving very little slack in the PCB layout. Watch this on-demand webinar to learn why it's imperative to match track lengths in high-speed data systems and differential signals. You’ll see how to properly define PCB length matching and time delay constraints, and how to effectively route high-speed signals in Altium Designer®.

In this article, we want to get closer to a realistic description of tight coupling vs. loose coupling in terms of differential pair spacing, as well as how the differential pair spacing affects things like impedance, differential-mode noise, reception of common-mode noise, and termination. As we’ll see, the focus on tight coupling has its merits, but it’s often cited as necessary for the wrong reasons.

You’ve possibly gone through plenty of engineering design reviews, both on the front-end of a project and the back-end before manufacturing. Engineering design reviews are performed to accomplish multiple objectives, and with many engineering teams taking a systems-based approach to design and production, electronics design teams will need to review much more than just a PCB layout and BOM. Today’s challenges with sourcing, manufacturability, reliability, and mechanical constraints are all areas that must be confronted in real designs

One of the most common points of failure of a device occurs even before you start to layout your circuit board. Mistakes in your schematic design can easily make their way all the way into prototypes or production without a second thought once layout starts. In this article, I’m not going to extol the virtues of a good schematic design. Instead, this article is a simple no frills checklist.

One common question from designers is current-carrying capacity of conductors in a PCB. Trace and via current-carrying capacity are legitimate design points to focus on when designing a new board that will carry high current. The goal is to keep conductor temperatures below some appropriate limit, which then helps keep components on the board cool. Let’s dig into the current state of thermal demands on vias in PCBs and how they compare to internal and external PCB traces.

SPICE simulation saves you critical time in the prototyping phase. Understanding your simulation interface makes it simple to analyze how your circuits work in different scenarios. Altium Designer provides an intuitive, dedicated interface to support your simulation verification, setup, and analysis directly in your schematic environment. You also benefit from growing support for popular model formats, as well as generic models, simplifying circuit definition and simulation.

A combination of good printed circuit board design and good shielding mitigates EMI. Good PCB design for EMI shielding revolves around the layout, the placement of filters, and ground planes. A well-designed PCB minimizes parasitic capacitance and ground loops. Keep reading to learn more about PCB shielding.

Any project can get very complex, and the PCB design team needs to track revisions throughout a project. Why worry about tracking revisions? In the event you ever receive changes to product functional requirements, major changes are made to your product’s architecture, or you’re ready to finalize the design and prepare for fabrication, it’s best to clone a project at its current state and begin working on a new version. Keeping track of all these design changes in a PCB design project takes the type of hardware version control tools you’ll find in Altium 365™.
