Hi, I’m an electrical engineering student at University of Nottingham who need to design a pcb for my final year project. I’m designing a buck converter and I’ve counter few problems while designing it:
- I’m using a D-PAK (TO-252) mosfet. Everything is fined until when I’m about connect the track to the pad. This package got 2 small pad and 1 large pad which the small pad are gate and source while the big one is drain. But the software detect the large pad as gate. Any idea how can change it? Fyi Im using Q_NMOS_DGS in the schematic.
- I’ve already created a PCB with all footprint and track in it. But suddenly I’ve put a wrong component in the schematic. Can I still change a component in the schematic and change it to my current pcb design without messing up with my other component and track that’s been connected?
