Lee Ritchey 2014 confirmed

by

Lee RitcheyI am happy to announce that we have now confirmed that we will be able to arrange the two signal integrity courses with Lee Ritchey again in 2014. Exact place and time is not set yet.

This is where you can help – please vote here.

Lee Ritchey 2014 will have both the full 3-day general signal integrity course and the new 1-day stackup design course. We are looking forward to this. Expect the courses to run around May/June 2014.

Make sure you are alerted when the dates are known by signing up for the newsletter from EE-Training.

Thanks for Stockholm SI Week 2013

by

  The first Stockholm SI Week was a great success with more than 70 engineers attending 4 different courses in the wide field of signal integrity. I want to thank each of you for making this a great week for all. All participants took advantage of the course format to ask a lot of questions… Read more

Elektronik i Norden: En hel vecka om signalintegritet

by

Today “Elektronik i Norden” had the Stockholm SI Week in their great email newsletter. http://www.elinor.se/index.php/En-hel-vecka-om-signalintegritet.html Thanks to Göte Fagerfjäll who must be Mr. Electronics Press of Sweden. I enjoy reading the weekly commentary, often with some interesting personal reflections. We need more of that. And yes, there are still free seats 🙂 BTW: Also good… Read more

Sorry for all the bad links

by

We had some bad links go out recently – sorry about that. When software becomes too complex to debug using an oscilloscope, that is what happens. Apologies. Here are the two stories which went out with bad links: Polar is now sponsor for the Stockholm SI Week – and this could mean a free course… Read more

Nicest Eval Board Ever: The Crazyflie

by

The nicest eval board out there? This got to be the Crazyflie.  This “evaluation board” (that’s what you call it when you ask your boss if you can order it) is showing off what you can do with a Nordic Semiconductor 2.4GHz chip. And yes: It was developed in Sweden 🙂 so quite suitable as… Read more

Cu Roughness and Trace Loss Explained (Lee Ritchey video)

by

Skin-effect pushes the current to the outer part of any metal conductor, which is why we need to worry about Cu roughness. For copper, as it is used on a printed circuit board (PCB) the effective skin depth goes like this over frequency. With signaling speeds on PCB going to 28 Gbit/s (example: FPGA’s in… Read more

Copper Foil Acronyms for PCB Stackup Design

by

Designing a good stackup starts with understanding the materials. And luckily the materials of a PCB are pretty simple. Glass fiber, epoxy, and copper foil, right? Well, if you follow the discussions about losses due to skin effect, dielectric loss, etc. triggered by the constantly higher signaling speeds required, you will know that the devil… Read more
