Q301 and Q801 both have SOT-23-6 footprints when the physical part is really just a SOT-23.

As the board is in the middle of SMT we cannot change the PCB design. To wire-mod this batch I propose we do the following:

Part Pcbnew 3D
Q301 image image
Q801 image image

In both cases, there is a large 5V trace near by that we can shave the soldermask off of with a blade and connect the source of the mosfet to.

Another alternative solution is to find a mosfet with a pinout matching GDS instead of GSD so the middle pin could be extended into the pad 5. This would have a cleaner and more reliable mod but would have a longer lead time and cost as we would need to order new mosfets.
