1. A device, comprising:
a first printed circuit board;
a second printed circuit board;
wherein the first printed circuit board comprises a first rigid portion of a flex-rigid type printed circuit board, the second printed circuit board comprises a second rigid portion of the flex-rigid type printed circuit board;
walls coupling the first printed circuit board to the second printed circuit board and defining a first cavity between said first and second printed circuit boards;
electric conductors associated with said walls, said electric conductors electrically connecting the first printed circuit board to the second printed circuit board, wherein a flexible portion of the flex-rigid type printed circuit board supports said electric conductors;
an integrated circuit chip supported by a first surface of the first printed circuit board in the first cavity, said integrated circuit chip electrically connected to conductive tracks of the first surface of the first printed circuit board; and
surface-mounted components supported by and in contact with conductive tracks of a first surface of the second printed circuit board;
wherein the first surfaces of the first and second printed circuit boards face towards each other.
