BGA Ball Placement Vision System is a PC-based stand-alone vision system comprised of the QC vision designed for inspecting quality and checking for the presence of balls of frames placed on ball lands after performing ball tool visioning and ball attachment for inspecting quality and checking for the presence of the balls of ball tools, and the align vision that is used for transmitting offset values (positions, angles) different from the original positions by inspecting align marks with the vision in order for the balls of CSP(chip scale package)-family devices to be moved to accurate target positions after calibrating the positions and angles between the ball tools and the PCBs prior to placing the balls on the ball lands.
