Julian Ferry, Samtec’s Principle R&D Engineer, recently explained to our friends at Connector Supplier how choosing a connector for mezzanine board-to-board applications presents challenges in several engineering disciplines. Signal integrity concerns make the selection even more complex. Check out Julian’s article here. Julian discusses a variety of topics, including physical requirements, mechanical performance, considerations for high-speed data parameters such as return loss, … [Read more...]
More On 25+ Gbps Backplane Design
I recently posted a blog about videos of Teraspeed®’s Scott McMorrow explaining how he determined the materials to choose in order to achieve the best performance for a backplane system with a 25 Gbps+ operation. Xilinx’s Xcell Daily Blog also reported on these videos, and they tell us more about the setup, including eval boards used (Xilinx VCU109) and the FPGA selected (Virtex UltraScale VU095), among other details. Check out the Xilinx blog here. I encourage you to check out Xcell … [Read more...]
At What Data Rate Do You Use Photons To Push Data?
Check out this silicon photonics article in EDN – “Silicon photonics: Will the hare finally catch the tortoise?” -- by Ransom Stephens. He asks Sylvie Menezo (Director of France’s IRT Nanoelectronics Silicon Photonics Program) at what data rate do you think engineers will have to focus on designs that use photons to push data? I think it’s a great discussion and article. FYI ... Ransom Stephens’ is a technologist, science writer, novelist, and Raiders fan Electronic Design … [Read more...]

Samtec helps engineers design high performance electronic systems. With the recent integration of Teraspeed® Consulting into the Samtec family, we now provide more access to our advanced systems design research, helpful videos, conference presentations, white papers, etc. Here’s a link to two videos you should check out. Scott McMorrow, an R&D Consultant for Teraspeed® Consulting, explains how he performed extensive analyses of PCB materials for terabit backplane designs. His … [Read more...]
Advice On Selecting and Processing Connectors
If you're reading this, chances are you work with board level interconnects and are familiar with design and processing issues that affect them. If your job doesn’t require you to work with connectors, but you’re still reading this, then you are probably messed up and need some type of professional help. Assuming you're in the first group, check out the list below. This is from Phil Eckert, Samtec’s Customer Quality Engineering Manager. Phil’s career includes connector design, quality … [Read more...]
DesignCon 2015 Paper Now Available – “Optimizing Symmetry In Open Pin Field Designs
Samtec and Teraspeed Consulting presented several papers at DesignCon 2015. The first is "Optimizing Symmetry In Open Pin Field Designs." This paper presents a process for analyzing open field array structures. Various modes of propagation and coupling within the array of conductors are studied. We find that, counter intuitively, the use of additional ground structures can be detrimental to performance. It is demonstrated that by careful use of symmetry, high signal density can be achieved … [Read more...]
DesignCon 2015 Paper – Anisotropic Design Considerations For 28 Gbps Via to Stripline Transitions
Teraspeed Consulting and Samtec presented several papers at DesignCon 2015. Here's a link to "Anisotropic Design Considerations For 28 Gbps Via to Stripline Transitions." For 28-56 Gb/s design the homogeneous isotropic material assumption is a key impediment in model to measurement correlation. Without accurate dielectric material models, it is impossible to close the loop between electromagnetic modeling and actual operation. Epoxy/glass PCB materials present a layered-anisotropic dielectric … [Read more...]
“Causality De-Mystified” Is Best Paper Finalist At DesignCon 2015
Samtec’s paper “Causality De-Mystified” has been selected as a finalist for a Best Paper Award at DesignCon 2015. The papers are ranked in terms of Quality, Relevance, Impact, Originality and Commercial Content with the aggregate score determining the ranking. Papers with the highest ranking are selected for a Best Paper Award with the live presentation serving as the final award criteria. Awards for this year’s conference will be presented in January 2016 at DesignCon 2016. Causality is … [Read more...]
Julian Ferry Interview On High Speed Interconnect Design Developments
Julian Ferry, Samtec’s High Speed R&D Manager, recently spoke to Connector Supplier about the latest developments in high speed interconnects, the applications driving them, and how Samtec is meeting the challenges. Here is a full copy of the interview, courtesy of Connector Supplier. Q&A: Samtec on Signal Integrity.
