One topic that garnered much interest at the Samtec booth at the International Microwave Symposium was a dynamic stress test of Samtec's microwave cable. This demonstration proves that our low-loss, microwave cable withstands high flex cycles and still maintains signal integrity. In this video, Steve McGeary, Samtec’s Director of RF Business Development and Product Management, walks us through the demo and reviews the cable's insertion loss and return loss results, all in about two … [Read more...]

Let’s Get Small: Microelectronics In Biomedical Devices
Samtec’s Brian Niehoff presented “Biomedical Solutions: Integrating New Chips, Packages, and Modules” at the recent BIOMEDevice conference and exhibition in Boston. To give a super-quick synopsis, Brian explains how microelectronics are incorporated into medical devices and diagnostic equipment. Since he’s a Samtec guy, he also elaborates on Samtec Glass Core Technology (GCT), a proprietary process that leverages the performance benefits of glass, and how it can be also be used in … [Read more...]
Micro, Rugged Industrial Connectors: Do They Exist?
The Loch Ness Monster? There's that old, grainy picture. Big Foot? I've seen the video. UFO's? Who knows? But micro, rugged industrial connectors? Come on, that's really hard to believe ... But, industrial electronics is Samtec’s largest selling industry sector, and that's because Samtec has a full line of micro, rugged industrial connectors. Applications include factory automation, embedded computing, robotics, monitoring, vision systems, measurement, motion and process controls, and … [Read more...]
Can A 12G-SDI Signal Be Transmitted Through 12 Cable-to-Board Terminations?
Chris Shelly, Samtec’s RF/SI Modeling Engineer, walks us through a live 12G-SDI transmission line demonstration at NAB 2019. This demo showcases the signal processing capabilities of the Phabrix® QX UHDTV 12G-SDI generator/analyzer and the transmission of those signals through several other Samtec 75 ohm PCB connectors and cable assemblies. The Phabrix QX is generating a 12G-SDI signal, through two Samtec right-angle BNC connectors, and back into the Phabrix QX for analysis. We get a good … [Read more...]
Live Return Loss Demonstration Of 12G-SDI Connectors At NAB 2019
This live demonstration from NAB 2019 compares return loss performance of Samtec 12G SDI RF connectors per SMPTE ST-2082-1 12G-SDI requirements. In this video, Chris Shelly, Samtec’s RF/SI Modeling Engineer, compares the performance of Samtec's industry standard edge mount BNC connectors to a 75 Ω right-angle BNC, an HDBNC and a DIN 1.0/2.3, and he shows how optimized launches improve performance. The standard edge mount BNC connector has excellent performance of approximately -20 dB … [Read more...]
An Eye Catching High Performance Test Point System
Samtec Bulls Eye® test point systems are ideal for high-performance test applications because of their compression interfaces, small footprint, and high cycle count capabilities. Bulls Eye is now available in 50 GHz and 20 GHz designs, with a system up to 70 GHz in development. Bulls Eye is a popular product because: The grid design and smaller footprint enables smaller evaluation boards and shorter trace lengths. The high-density array design significantly saves PCB space compared to … [Read more...]
Creepage and Clearance and Why We Care About It
Every day Samtec’s Application Support Group answers questions about a connector's mechanical, thermal, and electrical performance. One frequently discussed topic is connector creepage and clearance. Creepage and clearance is ultimately about safety and meeting regulatory standards, regardless of the system design. The ongoing trends to reduce PCB size and increase density become a design challenge when these smaller, denser PCBs incorporate high voltage circuits. Dave Scopelliti, President … [Read more...]
Solder 0.15 mm Coplanarity Connectors With a 0.10 mm Stencil
COPLANARITY AND STENCIL THICKNESS STUDY Samtec and Phoenix Contact recently completed dual studies that show when PCB processing requirements dictate using a 0.10 mm (.004”) stencil, the coplanarity requirements for most connectors can be relaxed to a maximum of 0.15 mm (.006”). In other words, Samtec and Phoenix Contact both successfully soldered PCB connectors with 0.15 mm coplanarity using a 0.10 mm thickness stencil with optimized apertures. CHALLENGE FOR DESIGNERS Designers know … [Read more...]
Rugged Interconnects For Industrial Applications
Many industrial electronics OEM designers use the word "rugged" to describe their board-level interconnect needs. While rugged can mean different things to different people, it usually includes the ability to withstand high shock and vibration applications, maintain mechanical and electrical integrity after exposure to both harsh environments and high mating cycles, and provide EMI shielding attributes, to name a few. Designers in the mil/aero, high-performance computing, telecom, and datacom … [Read more...]
