Everything You Need to Know About Ferrite Beads As noted in my previous blog regarding PDS design, the whole power supply conundrum is one that has been plagued over the years with a number of erroneous rules-of-thumb; “black magic” design rules and confusion as to what does or doesn’t work. One of the most controversial topic areas focuses on the use of ferrite beads as a means of controlling and containing EMI. There is conflicting information concerning the use of ferrite beads and it is Read Article

Better PCB Routing - Highlight Nets Regardless how many PCBs I design, I always find myself having to regularly review network paths on schematics layer and trace routes on PCBs. The complexity reminds me of a maze where only one path is the right one for a particular network. It is imperative that all the connections are accurate as errors made here will come back to haunt you later in the form of redesigns. The best way to ensure network accuracy is by isolating it so that each Read Article

High Currents and Higher Temperatures: PCB Design Tips for Heat Management I remember the first (and hopefully the only) time one of my circuits caught on fire. It started with the resistors and quickly spread to a nearby decoupling capacitor. Thankfully, the destruction was minor and most of the components were salvageable. Why did this happen you ask? No, this was not due to a short circuit. Very simply, I did not take into account the high current PCB layout. As electronics continue to be miniaturized, the thermal Read Article
