Abstract
An infrared image detector system mounted on a printed circuit board (PCB) is disclosed for use with an infrared imaging system such as an infrared camera. A semiconductor die having an infrared detector array and connection points on a first surface is mounted to a PCB and electrically coupled to electrical connection points on a PCB. In addition, a heat sink can be coupled to an opposing second surface of the semiconductor die. Still further, the PCB can have a window within which the infrared image detector array can be positioned so that the infrared image detector system can be mounted to one side of the PCB while infrared radiation incident on the second side of the PCB will reach the infrared image detector array through the window.
