As someone who’s struggled with balancing PCB trace safety and board size, this guide’s breakdown of IPC standards and real-world examples is super helpful—especially since it points to the <a href=”https://tracewidthcalculator.com/”>PCB trace width calculator</a> to take the guesswork out of getting those critical width calculations right. I’ll definitely use it next time I’m designing a power rail for an MCU, since the safety margin tip alone could save me from costly reworks.
