A complex device that integrates a beam shaping aperture in a printed circuit board of the complex device (e.g., scanner or barcode reader or optical module) is provided. The complex device has a light-emitting diode pattern projection system. The pattern projection system includes one or more light-emitting diodes and a printed circuit board. The printed circuit board has one or more apertures and one or more receptacles. The one or more receptacles are positioned behind the aperture and receive the one or more light-emitting diodes. The printed circuit board with receptacle offer self-alignment for the light emitting diodes. The beam shaping aperture in front of the light-emitting diodes allows light to pass through the aperture that is part of the printed circuit board layer of the complex device.
