Samtec engineers and support associates are asked countless questions on a wide variety of connector topics, from ways to improve manufacturability, how we test our connectors, how to select the right connector, what plating option is best for my connector, to EMI shielding and connectors. It’s quite a coincidence that I should mention EMI shielding…
In a recent Samtec gEEk® spEEk episode, SI/PI gurus Scott McMorrow, Rich Mellitz, and Istvan Novak answered questions from the audience. Attendees asked questions on signal integrity and power integrity design that spoke to some emerging engineering challenges. In their responses, Scott, Rich, and Istvan emphasized the importance of rigorous analysis, careful tool characterization, and…
If you get your power design right, it protects the signal integrity margin and improves power and thermal efficiency. Some connectors combine power blades in addition to digital signal pins, which adds complexity. For these types of connectors, it is important to understand how the blade assignments impact power delivery as well as how the…
A new connector system improves signal integrity by improving power integrity. Optimizing power integrity provides greater signal integrity margin and improves power and thermal efficiency. The design of a high-speed connector system’s breakout region, or BOR, impacts signal integrity. The BOR of a power connector also impacts signal integrity. How do we create a BOR that…
Once upon a time . . . I really don’t like starting a blog out that way, but in this case, it applies. Bear with me. Like most undergrad Electrical Engineering students, I took “Introduction to Electromagnetics” my junior year. I thought it would straight forward due to previous exposure in Physics. Boy, was I…
Signal integrity (SI) and power integrity (PI) concepts confuse many seasoned engineers. Yet, they are both essential to modern, high-performance system architectures and system design. Designing for High-Speed “It’s all about the signal channel!” That’s it. That’s the short and simple secret to SI. As an electrical engineer, PCB design or SI specialist, routing a…
Samtec blog readers are used to hearing about high-performance design. However, we see an increase in intertest in power integrity (PI). PI grows more crucial with each design iteration, yet many engineers are just starting to understand PI. That raises an interesting question. How can an engineer learn more about PI? Samtec’s Istvan Novak will…
