Imaging based barcode scanner engine with multiple elements supported on a common printed circuit board

An apparatus for use in decoding a bar code symbol, the apparatus comprising:

• an image sensor integrated circuit, the image sensor integrated circuit having an image sensor including a plurality of pixels arranged in a plurality of rows and columns of pixels, timing and control circuitry for controlling the image sensor, gain circuitry for controlling the gain of one or more signals, analog to digital conversion circuitry for conversion of an analog signal to a digital signal, and a plurality of electrode pads on a surface of the image sensor integrated circuit;
• a printed circuit board receiving the image sensor integrated circuit, the printed circuit board having a plurality of contact pads disposed on a surface of the printed circuit board;
• wherein a connection between said image sensor integrated circuit and said printed circuit board is characterized by a plurality of conductive adhesive connectors disposed between the plurality of electrode pads on the surface of the image sensor integrated circuit and the plurality of contact pads disposed on a surface of the printed circuit board, the conductive adhesive connectors providing electrical input/output and mechanical connections between said image sensor integrated circuit and said printed circuit board;
• wherein the apparatus is operative for processing of image signals generated by the image sensor integrated circuit for attempting to decode the bar code symbol;
• and
• a first light source of an illumination subsystem and a second light source of an aiming subsystem positioned on said printed circuit board, the apparatus being adapted to direct light from the first light source and the second light source toward a field of view of the apparatus, wherein the first light source and the second light source are connected to the printed circuit board by an adhesive conductive connector disposed between at least one contact pad disposed on a surface of the printed circuit board and at least one conductive projection extending away from an at least one electrode pad formed on the first light source and the second light source.
