Run a high-power LED driver at full load for six hours on a standard FR4 board, and you’ll see the problem fast. The board runs hot, components drift out of spec, and lifespan drops sharply. Heat is the leading cause of premature electronic failure — and the substrate material you choose determines how well your […]
When making PCB for some applications, we often choose PCB. This time, we will tell you below how to distinguish aluminum substrate PCB from FR4 PCB. What is the difference between them? Each type of PCB has its unique characteristics, advantages, and applications. Understanding the distinction between these differences can aid designers in optimizing circuit […]
