  • the present principles relate generally to electronics and, more particularly, to an electronic apparatus and circuit board configurations within a vertical electronic device.
  • Electronic apparatuses or devices such as set-top boxes are typically assembled apparatuses having a plurality of walls wherein at least one of the walls is secured with a plurality of screws.
