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.

Should You Use Power MOSFETs in Series?

Power MOSFETs enable a huge range of electronic systems, specifically in situations where BJTs are not useful or efficient. MOSFETs can be used in high current systems in parallel arrangements, but what about their use in series? Both arrangements of MOSFETs have their pitfalls that designers should consider. Let’s look at MOSFETs in series as they are quite useful in certain systems, but be careful to design your circuits and your PCB for reliability.

Controlled ESR Capacitors: Should You Use Them for Power Integrity?

I can’t think of a single product I’ve built that doesn’t require capacitors. We often talk a lot about effective series inductance (ESL) in capacitors and its effects on power integrity. What about effective series resistance (ESR)? Is there a technique you can use to determine the appropriate level of resistance, and can you use ESR to your advantage?

Stripline Impedance Calculator

Striplines provide some advantages over microstrips as they take advantage of natural shielding and coupling from nearby ground plane layers. Although they tend to experience higher losses due to total confinement in the dielectric, they can be thinner due to the high dielectric constant used in internal layers of a PCB. Use our free impedence calculator to help you determine the correct width needed to hit a target impedance.
