Thanks to some VR magic, you can now tour Sierra Circuits from YouTube. Our brand new 360 video will take you to our Sunnyvale, CA facilities just like you were there for real.
Released last month, the PerfectPulse J2151A is the fast edge signal generator and TDR you’ve been looking for. Made by Picotest, the Phoenix-based high-resolution test company, the PerfectPulse is the new low-cost measurement equipment that will change your life. Or at least your work life.
As a circuit board manufacturer, designers often ask us about the difference between IPC Class 2 and Class 3. Class 1 does exist although we rarely produce boards that fall into this classification. Most of the times, even if the end-use of the product only requires Class 1. We will make it Class 2 just to ensure a better performance. This article will help you understand the different design rules for IPC Class 2 and Class 3 circuit boards.
At some level of circuit complexity, turning to an architecture with blind and buried vias will result in better yield and lower cost than would a through-hole design. In this presentation, we discuss several design examples and illustrate the relative costs and benefits of different architectural approaches.
For PCB designers and engineers, optimization is key. Optimization of time, cost, and even effort. Sierra strives to provide customers with high-quality PCBs and excellent service. This includes best practice tips for designers. When designing your next circuit board, you need to watch out for some crucial cost drivers.
