Can You Design a Rotation-Proof Connector Pinout? There are times where your connector pinout needs to be adaptable and reversible. What’s the easiest way to do this? Use a rotation-proof connector in your PCB. Read Article Transmission Line Impedance Measurement: Even vs. Odd Mode If you need an accurate transmission line impedance measurement, here are the important values you need to use in your next board. Read Article Power Delivery Systems Design This article is intended to define the new challenges and provide guidance in how to successfully engineer the Power Delivery System (PDS) so it meets the needs of new technologies. As integrated circuit technology allows for billions of transistors on a single IC, it has resulted in very powerful systems on a chip. This has made it possible to put the equivalent of supercomputers inside video games, cell phones, and a host of other products that Read Article Mastering Magnetism: Hall Effect Sensors and Applications for PCBs Magnetism allows you to do some really cool things—especially when electrons move through a magnetic field. One device that uses the deflection of electron motion for sensing is a Hall effect sensor. These little devices are used in automotive, manufacturing, consumer electronics, and other industries. The Hall effect basically allows a magnetic field to be sensed, which offers several possible applications. Some of the possible applications Read Article Controlled ESR Capacitors: Should You Use Them for Power Integrity? I can’t think of a single product I’ve built that doesn’t require capacitors. We often talk a lot about effective series inductance (ESL) in capacitors and its effects on power integrity. What about effective series resistance (ESR)? Is there a technique you can use to determine the appropriate level of resistance, and can you use ESR to your advantage? Like many answers to important engineering questions, the answer is “it depends.” One type of Read Article Routing Requirements for a USB Interface on a 2-Layer PCB In an earlier blog, I discussed some of the basic points in preparing routing rules for 2-layer PCBs to support routing and layout with digital signals. In particular, we looked at some of the basic stackup and routing rules needed to support a digital interface like I2C or SPI on a 2-layer PCB. When working with these interfaces, a few simple guidelines can help ensure signal integrity in your board and cut down on EMI. What about an impedance Read Article Ferrite Core Selection and Design Decisions When designing a transformer or using a ferrite core inductor, you must use the correct design process, and there is no substitution for real-world final testing. Let’s look at the process. Read Article Schematic Design Review Checklist This article is a simple, no-frills checklist to help you check schematics.
