Motor-Driver PCB Layout Guidelines (Part 1)

In Part 1, we’ll discuss some general recommendations for designing PCBs that use motor-driver ICs, which require special cooling techniques to handle the power dissipation. Printed-circuit-board (PCB ...

Motor-Driver PCB Layout Guidelines, Part 1 (.PDF Download)

Printed-circuit-board (PCB) substrate material, like FR-4 glass epoxy, is a poor conductor of heat. Conversely, copper is an excellent conductor of heat. So, more copper area on a PCB is ideal from a ...
