soldering iron and apply fresh solder to one of the solder pads. Using a pair of tweezers,
position the new chip component in place while heating the fresh solder. Once solder wicks onto
the new component, remove the heat from the solder. Heat the remaining pad with the soldering
iron and apply solder until it wicks to the component. If necessary, touch up the first side. All solder
joints should be smooth and shiny.

on the solder pads to smooth it. Apply a drop of solder paste flux to each pad. using a pair of
tweezers, position the new component in place. Position the hot-air hand piece approximately 1/8”
above the component and begin applying heat. Once the solder wicks to the component, remove
the heat and inspect the repair. All joints should be smooth and shiny.
