I recently attended the Engineering Design Show in the UK, where one of the clear trends in evidence was the rise of power connectors for printed circuit boards (PCBs). The reasons are pretty clear. New technology is making ever-greater demands for more power in smaller spaces. The march towards miniaturisation continues, while at the same time users want systems with more and more functionality. Modern applications are placing demands for power delivery to the printed circuit board … [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...]
Watch New mPOWER™ Ultra Micro Power System Video
In case you haven’t heard, there’s a new ultra micro power connector in town with an unmatched power-to-size ratio and incredible design flexibility. Sometimes it’s true, new is better. Let us count the ways: mPOWER™ ultra micro power connectors pass 21 Amps per blade in about half the size of a traditional power connector carrying the same amperage. These ultra micro power connectors (UMPT/UMPS) offer flexibility for power only or power/signal combinations with any high-speed signal … [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...]
Check Out This Design Upgrade to Our Connectors, Cables, RF, and Optics Pages
The top level of product categories on Samtec.com feature our Connectors, Cables, Optics, and RF pages, which give users a jumpoff point into the four main categories of products that Samtec sells. These pages were first released in 2016 with a very simple approach, to get the user to the next step in the process. With this update, these pages were given a much needed design update and several new features: All new product imagery and more neutral background colorsSide navigation to … [Read more...]
Is Copper Dead?
In 1995, I attended a seminar in which the presenter told us that copper was dead. This sort of statement is not new. The connector market is filled with armchair pundits who predict the demise of everything from D-Subminiature connectors (which are very much alive and kicking) to the V.35 telecommunications connector (which is as dead as the Dodo). This just goes to prove that it is almost impossible to predict the future trends of this industry with any certainty. Making … [Read more...]
Trade Shows and Why We Love ‘Em
Most people in the electronics industry have a complicated relationship with trade shows. On one hand, they sound fabulously glamorous – the chance to visit a faraway town, connect with customers and show off your latest products. The reality is a little bit more mundane. Yes, it might be exotic to visit Paris, Munich or San Fransisco, but the truth is that you rarely see much beyond the taxi, the hotel or the convention centre. Trade shows mean early mornings, long days … [Read more...]
The Future of Content
The word “revolution” is very common in today’s world. Whether it’s a revolutionary new smartphone or a revolution in personal transport, it is a phrase that is used frequently. How many of these things are truly groundbreaking, or how many are victims of marketing is a matter of debate. Marketeers never lie, of course, but we have been known to squeeze the last ounce of truth from a story to make it appear more attractive! What cannot be denied is the staggering pace of … [Read more...]
A 112 Gbps High-Density Escape From The System ASIC To The Front Panel
In this video from EDI CON 2109, Samtec's Jignesh Shah explains how Samtec Flyover® offers a 112 Gbps high-density escape from the system ASIC to the front panel. This is a live demonstration of 112 Gbps PAM4 traffic using Credo Semiconductors mixed signal SERDES with Samtec Flyover technology. First, Jignesh walks us through the signal path: Samtec High Density NovaRay Cable System A Credo Firebird SERDES generates 31-bit PRBS data at 112 Gbps PAM4 data rates.The signals travel … [Read more...]
A Connector Solution To Achieve 112 Gbps Data Rates
In the video above, Samtec's Jignesh Shah and Kevin Burt explain that as data rate requirements approach and surpass 112 Gbps PAM4, developers are challenged with balancing increasing throughput, scalability, and density demands with concerns such as power consumption, signal integrity, time-to-market, and of course cost. To hit these speeds, designers often have to use special board laminate materials with lower dielectric constants and dissipation factors. But the problem is, these … [Read more...]
