Keep Your PCB Assembly and Production Processes Like Your Best Pants: Seamless I lost a button on an old pair of jeans the other day and I was totally unable to repair it. The seams were all sorts of wonky, and while normally you can find extra buttons along the waist there were none to be found. My mom taught me to always check the seams, but sometimes it’s easy to get lazy and forget to do some of the most basic procedures when you want to get an otherwise grueling experience done with. Some brands are more trustworthy Read Article What Are Differential Pairs and Differential Signals? Differential pairs and differential signaling are the mainstay of high speed digital communication and data transfer. Read Article What is Signal Integrity? Learn about the basics of signal integrity and how you can ensure your PCB layout complies with best practices for signal integrity. Read Article MCAD CoDesigner - Rejection Comments MCAD CoDesigner now displays the complete history of accepted and rejected changes, along with any comments the engineer has entered if a change is rejected. The history of changes is shown in MCAD CoDesigner's panel, making the interaction between the electrical and mechanical engineers more transparent. As soon as changes are applied/rejected on one side, the engineer on the other side is notified, and any rejection comments are displayed Read Article ISM Bands Around the World ISM bands (industrial, scientific, and medical) are parts of the RF (radio-frequency) spectrum reserved for general use by, as the name suggests, scientific, medical, and industrial devices. Their creation was in response to specific demands by these industries for access to the RF spectrum to perform functions without having to compete with the traditionally intensive users of RF, the communications, and defense sectors. The critical thing to Read Article Project History in Altium 365 Altium 365’s Project History shows changes to the project's documents and the timeline since the project was launched. Read Article Interactive Commenting in Altium 365 With Altium 365 Interactive Commenting, your comments provide you instant access and complete visibility to any design changes, so your explanations are all in one place. Read Article Beginner’s Guide to ESD Protection Circuit Design for PCBs Circuit protection from transient voltages and currents can be applied with ESD protection circuit designs. Learn more about these circuits in our guide for new engineers. Read Article Choosing the Right Microphone for Embedded Applications If you need to capture sound waves for your electrical device to process, you'll need a microphone. However, microphones these days have become very advanced, and there are so many options to choose from. While there are relatively small dynamic microphones, they come with a broad range of options and technologies. They range from relatively simple and popular condenser-type microphones to state-of-the-art sound conversion solutions incorporating Read Article Buck Converter Regulator vs LDO for DC, AC, and RF: Which is Best? For small, low-current loads, LDO is usually the best option. What about a buck converter? Learn more about choosing between a buck converter vs. LDO in this guide. Read Article Avoid Re-Placing the Same Parts Over and Over Again with a Pre-Placement Checklist Sometime during the evolution of the automobile, car makers decided that reading and understanding engine gauges were too difficult tasks for the average driver. To remedy this they substituted the check engine light instead; unlike the malfunction indicators of today which are computer controlled warnings, those early check engine lights would only tell you of a problem once it was occurring. Reporting a problem after it occurs is not the Read Article Part 2: Why Your PCB Design Review Process Is Obsolete and What You Can Do About It As we established in Part 1 , the PCB design review and collaboration practices have room for improvement in many organizations. To address this, we developed Altium 365 . Let's examine how running a PCB project through Altium 365 compares to other methods. One source of truth, visibility, and version control To start using Altium 365, you need to create a workspace and a centralized location for your design files, libraries, and collaboration Read Article 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 What is PCB Star Grounding and Why Would Anyone Use It? PCB star grounding can encourage bad design practices that lead to radiated EMI emissions in your PCB layout. Read Article What is Multi-board Design? Want to know about multi-PCB design? Learn more about what is multi-board design and how to use native 3D design with ECAD MCAD collaboration aids complex PCB layout. 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 Designing a Multiphase Buck Converter for an RF Power Supply Consider a multiphase buck converter for the regulator stage in your RF power supply. Alongside envelope tracking, you can ensure high efficiency power delivery and transmission.
