In our latest survey, we have asked that our readers send in questions they might have for Happy Holden, and quite a few of them took us up on it! The questions that were posed run the gamut, covering technology, the worldwide electronics fabrication market, and everything in between. Enjoy.

The following is today's question and Happy's answer:
Q: Why do many two-layer boards work in low-speed applications, signal integrity-wise?
A: Two-layer boards, properly designed, will even work in high-speed applications! Even a single-sided board will. If the signal rise times are slow, signal integrity does not enter in the solution.
I-Connect007 Editorial Team
The I-Connect Editorial Team recently spoke with Bob Williams, managing director of Pulsonix. He discussed some of the new features in the upcoming version of the Pulsonix PCB design tool, Version 12, including collision avoidance and other 3D options that allow certain MCAD functions within the ECAD environment.
Pete Starkey, I-Connect007
Believing that I knew a bit about signal integrity and controlled impedance, I was pleased to take the opportunity to connect with an educational webinar that I hoped would extend my knowledge. In the event I was surprised at how little I actually knew, and the webinar was an excellent learning opportunity. The webinar was introduced and expertly moderated by Anna Brockman of Phoenix Contact in Germany.

If you have ever contemplated crosstalk, eye closure, power loss, or a list of other issues defined in this textbook, then you also need to understand what, why, and how stackups can and will impact your circuit’s performance. After all, the stackup is one of the few things that directly touches every single part of your design; therefore, you must set yourself up for the highest probability of success by establishing a strong foundation through a well-designed stackup.
