Connect the Dots: Five Best Practices for Designing Flex and Rigid-flex PCBsBreaking High-speed Material Constraints: Design007 Magazine — May 2024
May 14, 2024 | I-Connect007 Editorial TeamEstimated reading time: Less than a minute
The world of PCB materials used to be a fairly simple one. It was divided into two groups: the “traditional” laminates and the high-speed laminates developed especially for high-speed PCBs.
But then traditional laminates started getting better, and high-speed designers and design engineers took notice. The resin systems have improved to the point that designers are now using flavors of FR-4 for some high-speed PCBs, saving time and money, while streamlining the fab process. In this issue of Design007 Magazine, our contributors explain how to avoid overconstraining your materials when working with high-speed boards. Don’t miss it.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week
06/14/2024 | Nolan Johnson, PCB007This week’s must-reads are comprised of news which moves the industry forward. We’ve had quite a lot of news on a global scale, and they’re all good reads. To winnow down to just five, I chose either new information or interesting takes on ongoing industry stories. To that end, we have news about new capital equipment for advanced packaging, discussions of material selection and the imaging process during PCB fabrication, a columnist's ode to the best engineer she knows, and some optimistic news from the semiconductor industry.

The Pulse: Overconstraining: Short, Slim, and Smooth
06/06/2024 | Martyn Gaudion -- Column: The PulseEngineering is both an art and a science. The design engineer’s task is (almost) always to bring product to market that meets specifications at the best and most economical price suited to the appropriate end use requirements. From a PCB perspective, designers are faced with a bewildering and almost overwhelming choice of materials at their disposal.
Overconstrain? Underconstrain? Selecting Materials for High-speed Designs
06/06/2024 | Andy Shaughnessy, Design007 MagazineWhen selecting materials for a high-speed design, you need to be very familiar with the materials’ electrical characteristics, as well as the requirements of the PCB you’re designing. There are myriad details that need to be considered during the material selection process, and missing one iota can lead to your job being put on hold. We asked Stephen Chavez, principal technical product marketing manager at Siemens, to share his thoughts on material selection for high-speed designs. Steph discusses material constraints, stackups, and the cut-off point when a “traditional” laminate will (and won’t) work for a high-speed board.
