PCB Design Considerations and Guidelines for 0.4mm and 0.5mm WLPs

Using a wafer-level package (WLP) can reduce the overall size and cost of your solution. However when using a WLP IC, the printed circuit board (PCB) layout can become more complex and, if not ...

Motor-Driver PCB Layout Guidelines (Part 1)

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 ...

Motor-Driver PCB Layout Guidelines (Part 2)

6. SOT-23 and SOIC packages are typically used in low-power motor drivers. Standard leaded packages, like SOIC and SOT-23 packages, are often used for low-power motor drivers (Fig. 6). To maximize the ...
