The Pulse: Overconstraining: Short, Slim, and Smooth

06/06/2024 | Martyn Gaudion -- Column: The Pulse
Engineering 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 Magazine
When 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.
