ABSTRACT:
There is disclosed an electronic assembly for use in calculators, watches and so forth. The assembly includes an integrated circuit element having a plurality of positioning apertures at the periphery thereof and a circuit board (preferably, a flexible circuit film) having a plurality of terminals to be electrically connected to the respective terminals of the integrated circuit element and also having a plurality of positioning apertures. The assembly further includes an upper casing and a lower casing one of which has a plurality of positioning projections to be received within the positioning apertures in the circuit element and a plurality of positioning projections to be received within the positioning apertures in the circuit board, for determining relative position of the integrated circuit element and the circuit board with respect to the casing. Preferably, the integrated circuit element has a plurality of signal terminals extending from one side and one or more power terminals extending from a second side thereof and in a direction different from that of the signal terminals, with the latter in direct contact with battery terminals when the assembly is completed. The package of the integrated circuit element may be of a polygonal configuration including a pentagon or more and the whole of the integrated circuit element including the power terminals shaped substantially into a rectangle.
