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.

Reduce Common-Mode Noise in Your Power Supply with Impedance Balancing

Simple switching regulator circuits that operate in compact spaces, like on a small PCB, can usually be deployed in noisy environments without superimposing significant noise on the output power level. As long as you lay out the board properly, you’ll probably only need a simple filter circuit to remove EMI on the inputs and outputs. As the regulator becomes larger, both physically and electrically, noise problems can become much more apparent, namely radiated EMI and conducted EMI in the PCB layout.

Part 1: Why Your PCB Design Review Process Is Obsolete and What You Can Do About It

A PCB design review is a practice to review the design of a board for possible errors and issues at various stages of product development. It can range from a formal checklist with official sign-offs to a more free-form inspection of schematic drawings and PCB layouts. For this article, we will not delve into what to check during a design review process but rather look at how a review process itself usually unfolds and how to optimize it to get the most out of your time.

The Great PCB Layout "Rules of Thumb" Debate Rages On

To this day, I still see many PCB layout “rules of thumb” that first became common nearly 20 years ago. Do these rules still universally apply? The answer is a firm “maybe.” The discussion around PCB layout rules of thumb is not that these rules are correct or incorrect. The problem is that the discussion around these rules often lacks context, leading to the always/never type of discussion seen in some popular forums. My goal in this article is to communicate the context behind the common PCB design rules.

How to Design Your PCB Test Coupon and What You Can Test

As the operating speed of components has increased, controlled impedance is becoming more common in digital, analog, and mixed-signal systems. If the controlled impedance value for an interconnect is incorrect, it can be very difficult to identify this problem during an in-circuit test. However, testing is normally performed on a PCB test coupon, which is manufactured on the same panel as the PCB. If you want to get through board spins quickly and aid future designs, you might consider designing a test coupon and keeping it handy for future designs.
