Mount the Voltage Regulator
Locate the spot for the voltage regulator on the PC board, it's near the left side of the
___
board. You'll see that there is one large pad on the right side, and three smaller pads on the left
side.
___ Lightly tin the center pad of the three pads on the left.
___ While heating up the tinned pad, hold the voltage regulator in place on the pads. Make
sure that it's centered on the pads, then remove the soldering iron, and let it cool for 5 seconds
before you let go of it.
