Abstract: A miniature electronic device, an example of which being an electronic watch, includes a printed circuit board which is mounted in a case and which has an aperture. A battery extends into the aperture forming a substantially coplanar assembly of exceptionally small thickness. The printed circuit board also features the use of circuit paths disposed on the peripheral edge to connect selected circuit paths which are disposed on upper and lower surface of the printed circuit board. An alternative embodiment of the printed circuit board features the use of a digit drives chip mounted directly on top of an integrated circuit watch clip with wire bonds leading from selected pads on the digit drives chip to selected pads on the integrated circuit watch chip and to selected circuit paths on the printed circuit board.
