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

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

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

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

What Causes Gibbs Signal Ringing in High-speed Channel Simulations?
Gibbs ringing is both a measurement artifact and a calculation artifact that arises in band-limited channels. Make sure you understand how this arises due to transform and convolution operations.

How the Gibbs Phenomenon Produces Measurement Artifacts
The Gibbs phenomenon is a measurement artifact that can be mistaken for real signal integrity problems like ground bounce, ringing from reflections, or resonance on short lines.

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
