Low Pass Filter Simulation for Your PCB Design Many engineers will do some basic calculations by hand in order to understand their filter and amplifier circuits. However, for complex circuits that do not obey standard series and parallel rules, or that use nonlinear components like diodes and transistors, more sophisticated methods are needed. As such, designers need an easy-to-use but powerful simulation application to aid filter design and simulation. Some programs make simulations Read Article Build an Electronic PCB Schematic Symbols Library in Altium Designer Electronic symbols are the basis for the CAD documents you’ll create before you prepare a circuit board layout. An electronic symbols library contains basic symbols and figures that are used in electrical drawings, and they need to be linked to the PCB footprints that will appear in your PCB layout. When you need to prepare and organize clear PCB layouts and electrical drawings, you need a reliable source of CAD symbols and PCB footprints, and it Read Article Microstrip PCB Ground Clearance Part 2: How Clearance Affects Losses In a previous article, I provided a discussion and some simulation results on the necessary clearance between impedance controlled traces and nearby grounded copper pour. What we found was that, once the spacing between the pour and the trace becomes too small, the trace becomes an impedance-controlled coplanar waveguide (with or without ground). We also saw that the 3W rule for the spacing between the trace and the grounded copper pour is a bit 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 Packing and Shipping Your PCBs: Best PCB Packaging Standards I mailed my last Christmas present yesterday, a few weeks after the holidays are over. I’m only a little embarrassed; I like to do a very precise job with wrapping even if I’m not terribly concerned with punctuality. The package was for a friend overseas who had a craving for her favorite American candies. Let me tell you: a beautiful wrapping job on a bag of fun-size Butterfingers is no small feat. Circuit board packing and shipping are more Read Article Decoding PCB Fabrication Notes Your PCB fabrication notes contain important information that ensures your board can be manufactured exactly as you intend. See what you should include and what these mean. 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 5 Noteworthy Women in PCB Design Women in technology is a hot topic, especially how to get more women involved in technology-related fields. What I find most interesting about this subject is what motivates people to pursue a career in technology in the first place. In general, there are a lot of men in this field and, as a woman in tech myself, I think attracting new people to the industry is always positive. I encourage people to pursue careers in technology, no matter their 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 Troubleshooting EMC Immunity: How to Identify and Resolve EMC Problems Most PCB Designers wear many hats, and one of them is to solve EMC problems. How can you acquire this skill that is not offered in the university? Watch now or listen on the go!
