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...]
Industry Standards and Samtec – What They Are and Why We Are Involved (Part 2)
As was discussed briefly in Part 1, Industry Standards play a big role at Samtec. In addition to offering technical credibility and innovation, many of the standards we work with drive our current and future product designs forward. Take, for example, the three aforementioned standards… PC/104™ As members of both the Technical Work Group & Marketing Group, Samtec has taken a large role in PC/104 over the years. As one of the oldest and most recognized Embedded … [Read more...]
Industry Standards and Samtec – What They Are and Why We Are Involved (Part 1)
Cadillac vs. Ford. Fast food vs. fine dining. 24k gold vs. 25₵ plastic. The difference between all of these things: standards. Standards are what define the choices we make each and every day as to what we will invest our time and money in. But what do standards, in this case, Industry Standards, have to do with a connector company, and why are they so important to us? What is a Standard? To understand why, we first need to define what a standard is. In the … [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...]
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...]
VME (VITA) Expansion: Moving the Connector Industry Forward
In order to better understand the massive impact the VME (VITA) standard family has had in the electronics industry, it is helpful to review its past successes, its present values, and its plans for the future. A Brief History Lesson Since its conception in 1982, VITA has continued to focus on marketing, expansion, and integration within the connector world. Its primary focus was creating open standards for an open world. What’s an open standard you ask? An open … [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...]
A New High Speed Connector Rating That Accounts For The Entire System
Designers periodically ask us for a "general bandwidth performance rating" to compare two or more interconnect systems. Of course numerous variables affect the signal integrity performance of an interconnect, so a one-size-fits-all approximation definitely does not fit all. Now, a new approach allows system signal integrity engineers to compare relative performance of connectors and cable assemblies while factoring in noise contributions from and interactions with other parts of the … [Read more...]
Samtec Releases “SI? Why do I Care” ChalkTalk
Samtec is pleased to announce a new ChalkTalk entitled “SI? Why do I Care?.” Hosted by EEJournal, this newly released ChalkTalk details SI basics and how they affect connector selection. SI not just for "Experts” Most designs these days have high-speed interfaces that require a solid strategy for SI. This calls for understanding the "basics" of SI. The ChalkTalk defines each of the following terms and how it relates to connector selection and simulation. Insertion Loss … [Read more...]
Strength in Design: Variable Connector Material Options
Selecting the right interconnect systems helps ensure your design will meet the standards it is supposed to meet – whether it is a high-cycle application, or high shock and vibration, or an interconnect that is going to see very little stress in its life. The truth of the matter is, your design is only as good your connections. In addition to stacking height, pitch, solderability and a long list of other options, it is equally crucial to analyze which type of conducting metal or alloy … [Read more...]
