  • Apparatus and method for inspecting PCB-mounted integrated circuits
    Patent number: 10107853
    Abstract: A method and apparatus for testing the mounting of an integrated circuit on a printed circuit board using a ball grid array comprises directing an inclined laser beam from a line scan laser sensor at the integrated circuit, detecting the position of the lower edge of the integrated circuit from laser light backscattered from the integrated circuit and printed circuit board, determining through a trigonometric calculation the height of the integrated circuit above the printed circuit board following soldering of the ball grid array and comparing the height with reference data. The integrated circuit is deemed to have been successfully mounted to the printed circuit board if the height falls within a predetermined range.
