I am trying to solder some 2N7000 MOSFETs onto a PCB that I got manufactured, but the pads are very close together. When I try soldering the first leg on the MOSFET, I always end up shorting it to the other pad through the solder. The soldering iron I am using is relatively thin and heating at a temperature of 300 C.
Could I be applying too much solder or are there other things you should do to prevent this?
Below are images of the top and bottom of the MOSFET pads, marked as Qx on the top of the PCB:
