In grade school, we had timed math quizzes. With a sheet full of problems and the timer set, the goal was to answer as many as possible. The key to speed is TONS of practice and, honestly, memorization – knowing the problems so well that the answer comes to mind at first glance. Similar to me sitting at the kitchen table learning the times table to ace the next quiz, rapidly increasing signal integrity requirements have driven Samtec to internally develop hardware for high-level testing of … [Read more...]
The 10 Commandments Of Connector Design Verification Testing
What exactly is connector design verification testing (DVT) (sometimes called a Design Qualification Test)? What does it measure? What kinds of conclusions can you make about the connector’s performance? Wasn’t DVT, along with immigration policies, China, and handling the Covid-19 pandemic among the most contentious topics during the 2020 Presidential debates? Phil Eckert (Samtec’s Quality Engineering Manager) and Mark Shireman (Engineering Support Group/Test Lab Manager) share what, if … [Read more...]
Shaken, Not Stirred: An Introduction To Connector Vibration Testing
In his latest paper, Dave Scopelitti explains the ins-and-outs of connector vibration testing. In particular, Dave discusses the rationale, techniques, and procedures used to perform vibration testing at Samtec. Dave begins by telling us that connector vibration testing is routinely performed to assess the mechanical and electrical stability and performance of a connector when subjected to the types of vibration that may be encountered during normal use. The type of vibration and the … [Read more...]
PLDA Establishes PCIe 5.0 Link Via Samtec PCIE-G5 Connector
PCI Express® is taking over the world! Or maybe it just seems that way. PCIe® - born as PCI® - started as a simple CPU-to-I/O controller interconnect more than 20 years ago. Today, it is one of three interfaces (Ethernet and DDRx are the others) common in almost all computing platforms. Current and future system design are focused on leveraging the 32 GT/s lane performance of PCIe 5.0. Many development solutions - from IP, silicon and eval kits - are coming to the market. PLDA PCIe … [Read more...]
Testing is Not an Afterthought
Testing is the final step of any manufacturing process, and arguably the most important, and yet it can often be overlooked. Releasing a poorly tested product onto the market has destroyed more than one reputation for quality, and this is even more important in an age when information can be shared globally at the click of a mouse. At the same time, product testing has become hugely more sophisticated as the products themselves have grown more complex. Gone are the days when testing … [Read more...]
A Performance Comparison of Air-Cooled vs. Immersion Cooled Connector Systems
As computing power continues to increase, air cooled systems cannot meet current thermal requirements for HPC hardware systems. Power consumption, space and performance must all be considered during system design. Immersion cooling is a fast-growing solution to economically combat system heat, noise, power consumption and compute density. Samtec’s Brian Niehoff presented “Thermal Management of HPC Hardware Architecture via Immersion Cooling” at the Exhibitor Forum at SC20. Brian’s … [Read more...]
How do Samtec’s Connectors Perform in Outgassing?
If you are involved with ISO 9001 then you probably know that "continuous improvement" is the name of the game. After all Rome wasn't built in a day, and neither was Samtec's newly updated Outgassing Guide. Our first version of the Outgassing Flyer was focused on the information that we had at the time, but being Samtec, we didn't stop there, and that is the topic of today's blog. Third Party Testing In the past, industry wide, manufacturers have relied on the outgas testing that NASA … [Read more...]
Is it Uncomfortable at the Cutting Edge?
Innovation can sometimes be an uncomfortable business. The history of invention is filled with examples of ideas that were dismissed at the time, and it is the measure of the inventor whether they can bounce back from rejection. From Alexander Graham Bell with his telephone to Thomas Edison with the electric light bulb, there is a distinguished group of famous names who struggled to be taken seriously. There is something noble, or even romantic, about the idea of the lone … [Read more...]
Keysight Quickens Samtec 112 Gbps PAM4 Test and Development Time
Quicken design cycles. Shorter test times. Faster time to market. System architects, product designers and testing engineers have no doubt heard these mantras with every new project they start. Maybe they have had nightmares about these phrases as well! In any case, shorter design and test times and faster time to market are necessary in today's uber-competitive world. Samtec's product development team lives and breathes these mantras everyday. Thankfully, partners like Keysight help … [Read more...]
Keys to Magnetic Field Testing and Permeability
Each industry has its own standards and requirements that components must meet in order to be considered usable for that industry. There are some tests that are common between industries, such as outgassing, but more often than not there are going to be different requirements that must be met. For instance, manufacturers within the medical field can be interested in magnetic field testing and magnetic permeability, if their products are used in or near a Magnetic Resonance Imaging (MRI) … [Read more...]
