Solder reflow plays an important role in the success and performance of high-bandwidth RF connectors. Sometimes, when a high-bandwidth RF connector is soldered together with an optimized PCB launch, the results can be unpredictable. It is important to investigate the root causes of solder reflow variation and analyze what techniques can deliver consistent performance across frequencies. In a new white paper from Samtec, “Impacts of Solder Reflow on High Bandwidth RF Connectors,” authors … [Read more...]
Connector Plating FAQs: Practical Advice About What Works and What Doesn’t (Part 5)
This is the fifth and final installment of our series on connector plating FAQs with Phil Eckert, Samtec’s Quality Engineering Manager, and Matt Brown, Principal Engineer. As we've mentioned in just about every one of these blogs, the choice and quality of the connector plating (or surface finish) is critical to the success of the component, and it's a topic that generates many questions from our customers. Before we get to question set #5, here's links to the previous four connector plating … [Read more...]
Ganged SMPM: New High Density, Push-On RF Solutions
Samtec recently released Magnum RF™, which are ganged, multi-position SMPM blocks and cable assemblies for millimeter-wave applications. Magnum RF is ideal when space is limited and a high operating frequency is required. Ganged SMPM When more than one channel is required, the ganged SMPM design provides 40% greater density, requires less processing time, and provides better positional alignment compared to individual SMPM connectors. SMPM (Sub-Miniature Push-on Micro), is about 33% … [Read more...]
Practical Guidelines To Achieve Quality Connector Solder Joints: Part Three
Beyond the construction of the connector, another factor that is crucial to the performance of the connector on the printed circuit board is the quality of the connector solder joints. This is the third in a series of three blogs, which are interviews with David Decker, the Manager of Samtec Interconnect Processing Group (IPG). In these blogs, David answers some of the most frequently asked questions about connector solder joints. As stated previously, the goal in answering these … [Read more...]
Away from Home for Thanksgiving
Thanksgiving has always been a time for togetherness, for being with those you care about, and for celebrating another year. However, there are times when being together is not possible. Over the last few years, travel has often been difficult, discouraged, or even forbidden, which has left many of us away from our loved ones for Thanksgiving. It is worth remembering that Thanksgiving was created by settlers who found themselves thousands of miles away from their original homes. They had … [Read more...]
Power Integrity Book Returns to Print with a New Mission
Tis the season of giving thanks and showing gratitude to those in need. I'm thankful for the opportunity to tell you about my colleague Istvan Novak and his new book. I sat down with Istvan Novak, Principal SI/PI Engineer at Samtec, and discussed the reprint of his book, Power Distribution Network Design Methodologies. He explained, "During the pandemic, I received numerous questions related to power integrity, and, as a result, the book was reprinted to meet growing demand." Initially, … [Read more...]
Connector Plating FAQs: What’s New, Shelf Life, Corrosion, Solder Wicking
This is installment number four in our connector plating FAQs series of blogs. Why all the fuss about connector plating? Simply put, plating greatly impacts the quality and performance of the finished product, and Samtec receives countless questions on all things plating. So it makes perfect sense to us to have a series of blogs on connector plating FAQs. If you want to catch up, here's the link to connector plating FAQs #1, here's a link to #2, and here's a link to blog #3, you're reading … [Read more...]
New Standards for Storage Connectors
What was the inspiration that got you into engineering? I am sure that I followed the same path as thousands, if not millions, before me. LEGO blocks and model kits gave me the thrill of creating my own machines, and they lit the spark that makes me the geek that I am now. However much I have always been fascinated with large machines, I have never been in a position to design one. My designs have always been small – connectors and backshells. The chance to work on the next Apollo … [Read more...]
New RF Podcast: Emerging RF Interconnect Design Challenges and Solutions
Samtec's Jim Alexander and Pete Robinson recently spoke with Judy Warner on The EEcosystem. The conversation, recorded as a podcast, discusses how increasing frequencies and shrinking footprints impact RF connectors and PCBs. They also discuss new design considerations and solutions. Here's a link to that podcast (it's free -- no registration, no strings attached) While it doesn't replace the podcast, below are a few comments, ideas, strategies, and observations that are covered in the … [Read more...]
A Good Pair: New Tech & Product Overview Guides
Good things come in pairs. Peanut butter and jelly, Batman and Robin, Thelma and Louise, turkey and dressing, Kirk and Spock, terminal and socket – just to name a few. Samtec’s latest duo is another good pair that will spare you the sticky fingers (although a police chase would make for a really awesome story). Technology & New Product Overview Guide The Technology & New Product Overview Guide highlights the innovative solutions and industry-leading expertise that drive … [Read more...]
