EMC for PCB design: anything but black magic
EMC problems are often responsible for re-design cycles in PCB design practice. Due to ever shorter innovation cycles of for example cell phones or IoT applications, such as fitness trackers or smartwatches, and many other electronic products, these time-consuming re-design cycles should be avoided under all circumstances.

CR-8000 2020 Supports Electronic Subsystem Design
CR-8000 2020 is Zuken’s flagship PCB design platform, and I’m pleased to share some of the most exciting details of the new product release with you. But before we get into the new product release discussion, you may be wondering why we call it a platform and not a tool. CR-8000 2020 has all the bells and whistles for electronic subsystem development.

Inside Signal Integrity: Impedance Control - Part 2
In part 1 of this blog we took a back-to-basics approach and discussed line impedance and its effects in signal integrity. As every electrical conductor comprises capacitance, an inductance, and a frequency-dependent ohmic resistance, and with increasing frequencies, these electrical characteristics will influence and distort the signal.

Inside Signal Integrity: Impedance Control - Part 1
Impedance and impedance control are some of the oldest and most discussed topics in PCB design. They are especially important in high-speed design related to signal integrity. In this, the first of a two-part blog, we’ll go back to the basics of impedance/impedance control and consider what influences line impedance. In part two, we’ll set about controlling it.

Mastering Power Integrity: First Get Your Power Distribution System Right
I don’t think I’m generalizing when I say that designers working on complex high speed designs really don’t want to expend a lot of time and effort dealing with power integrity problems. And they especially don’t want to do it using tools that are detached from their design flow. In today’s complex PCBs, we’re talking advanced processors, complex FPGAs and superfast memories, which all share various voltage ranges.

S-Parameters: Microwave goes Mainstream for High-Speed PCB Design Part 1
I’d like to explain to you in straightforward terms what S-Parameters are and why they’re so useful. When I say “straightforward”, I mean that in a technical sense, but this is a specialised area. If you’re not designing high-speed PCBs, or you don’t know much about signal integrity, you might want to tune out now.
