Flyover QSFP28 For 56+ Gbps Applications
At DesignCon 2017, Jim Nadolny, Samtec's Principle SI and EMI Engineer, presented(1) a technical paper entitled “Design of Flyover QSFP28 (FQSFP Series) for 56+ Gbps Applications.” This white paper discusses the Flyover QSFP (FQSFP) approach for 56+ Gbps applications to overcome the limitations from the large loss on typical QSFP ports with surface mount to PCB traces. By replacing the PCB traces to twinax cables, they achieved 7 dB lower insertion loss at 40 GHz -- compared to … [Read more...]
Calculating Connector Mating and Unmating Forces
We are asked all kinds of questions about both the electrical and mechanical properties of our mated connector sets. This makes sense because interconnects are obviously electromechanical components. On the electrical side, the two we answer the most are: what is the current rating of a connector?how does Samtec establish a voltage rating? Mechanical FAQs include: how many cycles will this connector handle?do you test to my specifications?what is the force required to mate or … [Read more...]
Samtec Expands AccliMate™ IP68 Sealed Cable Solutions Product Line
We are expanding our line of standard and custom AccliMate™ Sealed Cable Plugs and Receptacles, including new crimp sealed bayonet latching circulars. These systems meet IP67/IP68 requirements for dust-proof and waterproof sealing, and they are designed for industrial, outdoor, underwater and other harsh environments. The CCP-12, CCR-12, and CCRB-12 Series were developed as cost effective solutions with optional metal shielding for cable-to-cable and cable-to-panel applications. They … [Read more...]
Fretting Over Fretting Corrosion
Last week I posted a blog about a paper on Interconnect Susceptibility To Galvanic Corrosion. The paper was prepared David Scopelliti, a longtime friend of Samtec. As I mentioned there, Dave has a wealth of test, application, industry, and processing knowledge, and is well-respected and well-known in the industry. That’s a polite way of saying he knows a lot and has been around forever (think Moses in a lab coat). See a picture of Dave to the right. He's either … [Read more...]
Samtec Helps Avnet Make 2016 “Hot”
At the end of every year, avid readers, editors, engineers, and fellow electronics nerds of EDN magazine vote on their top 100 products. From DACs to smart cameras, debug software to single-board computers, all aspects of the electronic world are fair game in EDN's Hot 100. Avnet Recognized in Hot 100 Recently, it was announced that two of Avnet's design solutions, its 10-Inch Touch Display Demonstration Kit and MicroZed Industrial IoT Starter Kit, were included in the … [Read more...]
Interconnect Susceptibility To Galvanic Corrosion
Our longtime friend Dave Scopelliti has prepared a succinct paper where he shares his insights on the issue of Galvanic (Electrolytic) Corrosion and interconnects. Dave has a wealth of test, application, industry, and processing knowledge, and is well-respected and well-known in the industry. That’s a polite way of saying he knows a lot and has been around for a long time. Think Moses in a lab coat. If you've ever seen Dave you understand what I'm talking about … [Read more...]
Flyover QSFP28 Technical Paper and PCIe®-Over-FireFly™ Product Demonstration at DesignCon 2017
DesignCon 2017 is right around the corner. As in past years, Samtec will have a large presence throughout the event. Our SI experts will present technical papers. Our application engineers will demonstrate new system-level solutions. Our product experts will discuss various new and emerging products that will be released throughout 2017. And if I'm there I'll be at the food court ... TECHNICAL PAPER Jim Nadolny, Samtec’s Director of Signal Integrity, will … [Read more...]
