    3 min

    Touch the soldering iron tip and fresh solder to the four anchor legs to mechanically lock the port to the board.

17. 17

    Solder rear contact pins

    4 min

    Carefully solder each of the small data and power pins on the back of the port using a fine-point iron tip.

18. 18

    Inspect pin solder joints

    2 min

    Use a magnifying glass to check that each pin has a shiny solder joint with no solder bridges connecting adjacent pins.

19. 19

    Reinstall motherboard

    2 min

    Place the motherboard back into the front frame housing, aligning the camera and sensor cutouts carefully.
