HOW TO FIT THE MOSFET

   

A further photograph showing how the MOSFETs are fitted. The MOSFET is held in place with tweezers (see left and right of the MOSFET). Then, heat is briefly applied to one of the pins to ‘tack’ it into place using residual solder on the pad. This locks it in the correct position. Next, fresh solder is applied to the other two pins, and finally the first pin is revisited with fresh solder.

Result - a correctly positioned MOSFET with three reliable solder connections.
