While air cooling is still a commonly used method to cool data centers, the industry is seeing HPC, AI, and scientific computing market leaders investigating either conduction cooling, or full-scale immersion cooling, for their next generation designs. In this video from SuperComputing 2019, Arlon Martin and the Samtec Optical Group are demonstrating the latest developments in full-scale immersion cooling. Using Samtec Flyover® technology and FireFly™ optical modules as an … [Read more...]
The Top 10 Connector Blogs Of 2019
Here’s a list of the top 10 connector blogs (i.e., the most-read Samtec blogs) of the last 12 months or so. Several of these were written a few years ago but are still very popular; I think of them as the blog equivalent of Dark Side of the Moon. 1. The Legacies of Sam Shine: Sam Shine, the founder of Samtec, passed away this year. Although he hasn’t been involved with the running of the company for the last 25 years or so, his impact on Samtec and the electronics industry was … [Read more...]
Embedded Optical Development Platform For FMC+
This video from Super Computing 2019 (SC19) showcases a new embedded optical development platform and reference design. This new solution combines the latest FPGA solutions from REFLEX CES with the FireFly™ Micro Flyover System® from Samtec. Matt Burns, Technical Marketing Manager from Samtec, walks us through the demonstration. One part of this new platform is the Sargon Stratix® 10 FPGA FMC+ Instant Development Kit from REFLEX CES. The Sargon platform provides FPGA developers the … [Read more...]
Chassis-to-Chassis, Mid-Board Connectivity Via 5 Meter Cable Backplane
A popular demonstration at Super Computing 2019 (SC19) was a collaboration between Samtec and eSilicon that emulates next generation data center architectures for typical 19 inch rack-mount applications. In the video above, Ralph Page, Systems Architect at Samtec, walks us through this chassis-to-chassis demonstration that shows mid-board connectivity via a five meter cable backplane architecture. It utilizes Samtec Flyover® to extend signal reach and density to achieve these next gen … [Read more...]
56 Gbps PAM4 Connector Product Demonstration
In the video above Ralph Page, Systems Architect at Samtec, walks us through a live product demonstration that received a lot of attention at Super Computing 2019. Ralph discusses several Samtec 56 Gbps PAM4 connector solutions and shares some incredible results. The system can also run up to 28 Gbps NRZ. This is a fully-packaged system that populates signal paths using real-world signal integrity design practices. It demonstrates up to 56 Gbps PAM4 signaling, utilizing Samtec Flyover® … [Read more...]
The Legacies Of Sam Shine
Sam Shine, the founder of Samtec, passed away on November 15 at age 86. Since his passing, several articles and obituaries have been written about Sam and his legacy. Rightfully so, most focus on his love for the Southern Indiana community, his local and national conservation efforts, and above all, his generosity. He is known locally for his recent purchase of Joe Huber’s Family Farm and Restaurant. This family-owned restaurant farm market, located in rural Southern Indiana, … [Read more...]
How To Design An Edge Card Connector For Rugged Applications
Edge card connectors -- or are they card edge connectors? -- are a popular design option. That's because they make it easy to plug and unplug a mating card that may require more cycling than standard PCBs, and because the socket allows for relatively easy system upgrades and repairs, and there’s less cost with only one connector, and less processing time also. Interest and usage of micro pitch edge card connectors continues to grow. As with any micro-pitch interconnect, the stresses of … [Read more...]
The Effects Of Lubrication On Connector Processing
Decisions, Decisions ... I may be in the market for a new car in the near future. Unless you’ve got a strong preference (and most car buyers DO have a strong preference, IMO), choosing a vehicle is a series of trade-offs. Fuel efficiency vs. horsepower. Functionality vs. appearance. Safety vs. fun. Cost vs. a heated steering wheel and seats. Choosing the right connector set for many EOEM applications is also full of trade-offs, including pitch, termination type, plating, and contact … [Read more...]
Connector Thermal Cycle Qualification For Military and Avionic Environments
Collins Aerospace recently published a white paper entitled “Qualification Of High Density Connector Solutions For Military and Avionic Environments.” It discusses their qualification process of high density connectors for rugged military and avionics applications. This paper focuses on the thermal testing of solder joints because “printed circuit board (PCB) assemblies are made up of many different materials that have different coefficient of thermal expansion (CTE) … [Read more...]
IDC or Crimp? May The Best Connector Win.
IDC or Crimp? When discussing options for cable assemblies, designers frequently ask if we recommend discrete wire cable assemblies with crimped contacts or insulation displacement connectors (IDC) with ribbon cable. Our answer is it depends on your application. Crimped connectors and IDC are both reliable connector systems and each has its own list of advantages and disadvantages. Before we get to those lists, just to make sure we’re all on the same page, here are quick definitions of each … [Read more...]
