Integrated circuit and electronic device comprising a plurality of integrated circuits electrically coupled through a synchronization signal

Abstract

An electronic device has a plurality of integrated circuits fixed to a support between transmitting and receiving antennas. An integrated circuit generates a synchronization signal supplied to the other integrated circuits. Each integrated circuit is formed in a die integrating electronic components and overlaid by a connection region according to the Flip-Chip Ball-Grid-array or embedded Wafer Level BGA. A plurality of solder balls for each integrated circuit is electrically coupled to the electronic components and bonded between the respective integrated circuit and the support. The solder balls are arranged in an array, aligned along a plurality of lines parallel to a direction, wherein the plurality of lines comprises an empty line along which no solder balls are present. A conductive synchronization path is formed on the support and extends along the empty line of at least one integrated circuit, between the solder balls of the latter.
