High Speed Backplane Design and PCB Layout Tips

If you need to connect multiple boards into a larger system and provide interconnections between them, you’ll likely use a backplane to arrange these boards. Backplanes are advanced boards that borrow some elements from high speed design, mechanical design, high voltage/high current design, and even RF design.  They carry their own set of standards that go beyond the reliability requirements in IPC.

PCIe 5.0 Signal Integrity and Analysis

The upcoming Gen6 version of PCIe is pushing the limits of signal integrity for many computer systems designers. As with any high-speed signaling standard, signal integrity is a major design consideration, which requires the right set of design and analysis techniques. Rather than digging deep to find PCIe 5.0 signal integrity requirements from PCI-SIG, we’ve compiled the important points for today’s PCB layout engineers. Layout engineers should pay attention here as these design requirements will become more stringent in later PCIe generations.

Image Processing Embedded Systems with Modular Hardware

With advances in industrial automation, automotive technology, remote sensing, and much more, image processing is taking center stage in many embedded systems. Image processing with older video systems was difficult or impossible due to the low quality of many imaging systems with perpetual uptime. Newer systems provide video with higher frame rates and higher resolution images, but these systems still needed to connect directly to a computer in order to enable any useful image processing applications.

Any Angle Routing: When Should You Use It?

EDA tools have come a long way since the advent of personal computing. Now advanced routing features like auto-routers, interactive routing, length tuning, and pin-swapping are helping designers stay productive, especially as device and trace densities increase. Routing is normally restricted to 45-degree or right-angle turns with typical layout and routing tools, but more advanced PCB design software allows users to route at any angle they like. So which routing style should you use, and what are the advantages of any angle routing?
