    What Happens to Layer Changing Vias When Using PCI Express at Higher Speeds? In our one, two and three-day courses, which we conduct at technical and trade conferences as well as at private on-site classes, we will frequently be asked about particular technology trends and their impact on current design undertakings. Of late, a number of these questions have focused on how the use of PCI Express (also known as PCIe) at higher frequencies impacts layer changing vias. This article will address layer-changing vias, which Read Article

    RGB + White LED Strip Controller I’ve been playing around with RGB LED strips recently for lighting up my test equipment rack as well as some display shelves. On the display shelves, I have the RGB LED strips behind the shelves, which gives a great definition to the objects on the shelf. But I also want to have a high CRI white LED strip on each shelf to light up the objects. Typical RGBW LED strips available through online marketplaces do not have very good white LEDs, and I’m Read Article
    This is the DRC You Need to Add I was impressed that, right out of the box, the stock Design Rule Checks (DRCs) in my copy of Altium 20 pretty much covered all the bases on how to make a “standard” Printed Circuit Board (PCB). Altium defaults to “10 mil” rules, which means that the standard spacing and widths of copper tracks is 10 mils. What's more, most of the other spacings also default to 10 mils; pads to tracks, through-holes to other pads or vias. The exceptions being the Read Article
    Know the Power Dissipation Understanding power dissipation of an individual component, an electrical block, or even the whole electronics system is essential for electronics engineers. It is important not only to avoid exceeding the maximum limits of components but also to calculate unknown parameters in input or output sides because power dissipation is related to system voltage and current. In this article, I describe my practices for analyzing power dissipation in Read Article

    US Department of Transportation Seeking Alternatives to GPS GPS-capable devices range from your phone to your smartwatch; simply type in your destination and follow the directions. Simple, right? According to the Washington Post, we should all stop using GPS as it’s ruining the navigation centers of our brains. Despite the neurological effects on perception and judgment, the U.S. Department of Transportation (DOT) aims to find alternatives to GPS to provide redundancy. What started as a defense initiative Read Article
