Solder the other two smaller leads, then solder the large tab to its pad on the board. It's
___
OK if there's a pretty fair amount of solder on the pads... that will actually help with heat
conduction.
___ If necessary, go back and resolder the pad that you tinned earlier.
Mount the Rectifier Diode
Locate the spot on the PC board for the diode, it's at the far left side of the board and
___
has a mark with an arrow and a line at one end.
___ Tin the right pad of the diode.
___ If you look at the diode, you'll see that the package has a stripe at one end. This stripe
must match the line marked on the left side of the PC board pads.
___ Hold the diode in place so that the line is on the left side of the pads, then heat up the
tinned right pad until the solder flows. Remove the iron, then wait 5 seconds before letting go.
___ Solder the left pad to the diode. If you need to, resolder the right pad that was
previously tinned.
