4) Place the new component on the circuit board. Be sure that it matches the footprint. 5) Solder the new component. RJ45 connector CN105 Repair the RJ45 connector: 1) Use a soldering iron and a de-soldering pump to remove as much solder as possible from the pin. 2) Lift the CN105 connector from the circuit board. 3) Place the new component on the circuit board. Be sure that it matches the circuit board footprint. 4) Solder the new component. USB3.0 connector CN103 Repair the USB connector: 1) Use a hot air gun to melt the solder on the pins. Pin solder with soldering iron and absorber. You can gently push down with the soldering iron once everything is molten to move the CN103 out of the through holes. 2) Lift the CN103 connector from the circuit board. 3) Place the new component on the circuit board.
