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 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people to pursue careers in technology, no matter their Read Article Part 2: Why Your PCB Design Review Process Is Obsolete and What You Can Do About It As we established in Part 1, the PCB design review and collaboration practices have room for improvement in many organizations.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! Read Article Part 1: Why Your PCB Design Review Process Is Obsolete and What You Can Do About It A printed circuit board (PCB) design review is a practice to review the design of a board for possible errors and issues at various stages of product development. It can range from a formal checklist with official sign-offs to a more free-form inspection of schematic drawings and PCB layouts. Some companies do it completely in-house, while others get help from design firms and contractors. In many cases, they involve their contract manufacturers Read Article Current Limiting Resistor LED Systems with Matching Voltage Power Supply Most of my friends in engineering live a balanced lifestyle. However, there are some engineers that are workaholics. These engineers do not limit their working hours and are constantly dealing with stress. Their lifestyle is not so different from an LED’s that is directly connected to a power supply without a current limiting resistor or with the wrong resistor value. They start out strong, but eventually flicker and burn out. In the architecture Read Article Best Practices for DNI/DNP Components in Your PCB BOM You can use the DNI/DNP designation on components in your PCB BOM to create design variants as long as you’ve created your layout correctly. Read Article Efficient Heat Dissipation with SMD Heat Sinks Keeps You From Dropping PCBs In electronics, there is the possibility that your PCB can get pretty hot due to power dissipation in certain components. Whenever a component reaches an extreme temperature that goes beyond a component's safe operating range, its lifetime will be greatly reduced or the component may fail immediately. The heat-producing component being defective means the entire PCBA will need to be scrapped. There are many things to consider when dealing with Read Article PCB Simulation: How to Simulate a PCB Design Looking for the best PCB simulator? Get started with an electrical circuit design simulation software and learn how to simulate a PCB design. Make sure you use the best PCB simulation software in Altium Designer's unified environment. Read Article Testing the Limits of Your LDO's Efficiency The efficiency of your LDO isn’t a fixed value, but neither is your maximum current output. Read about your LDO efficiency curve to better see why LDOs have narrow operating ranges. Read Article Use the Best Circuit Drawing Software With SPICE and Schematic Capture Use the best circuit schematic editor to create your next electronic design and start your PCB layout.
