“Don’t let the smoke out!” That’s one of the PCB designer’s unspoken objectives, albeit a sarcastic one. The idea is that there’s a cloud of smoke inside each printed circuit board, and if you don’t design the board correctly, you’ll let all the smoke out. And in high-voltage boards, you might say that there’s a lot more smoke trapped inside, just waiting to get out and set your schedule back a few weeks.
In our recent surveys, readers mentioned high-voltage PCBs among the challenges that they’re facing as the automotive segment, electric vehicles in particular, demand higher voltages. So, in the January 2022 issue, we asked our contributors to share their thoughts on designing high-voltage PCBs.
