Length Matching in High Speed Buses

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®.

Tight versus loose coupling

Should You Use Tight vs. Loose Differential Pair Spacing and Coupling?

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.

How to Solve Your Engineering Design Review Challenges

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

Schematic Review Checklist

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.

PCB Via Current-Carrying Capacity: How Hot is Too Hot?

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.

Best Practices in Hardware Version Control Systems

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™.

Copper Pour and Via Stitching: Do You Need Them in a PCB Layout?

To pour or not to pour, to stitch or not to stitch… Over many years, some common “rules of thumb” have become very popular and, ultimately, taken a bit out of context. Rules of thumb are not always wrong, but taking PCB design recommendations out of context helps justify bad design practices, and it can even affect the producibility of your board. Like many aspects of a physical PCB layout, via stitching and copper pour can be like acid: quite useful if implemented properly, but also dangerous if used indiscriminately.

Altium Designer Signal Integrity
On-Demand Webinar
What is High-Speed Design?

The primary source of high-speed problems is not due to high clock frequency but rather the fast rise and fall times of component signals. With fast edge rates, reflections may occur at the receiver side, and when the board routing is dense, crosstalk may become a problem. During this webinar, you'll sharpen your knowledge and develop new skills that you can use to design High-Speed PCB's more efficiently and effectively.
