Abstract:
Methods and apparatus for alignment in a flip chip bonding. A method includes attaching an integrated circuit having connector terminals to a bonding arm, the bonding arm having a chuck for attaching the integrated circuit at the backside surface, the bonding arm having a plurality of CCD imagers mounted thereon; receiving a substrate having pads corresponding to the connector terminals; using the bonding arm, positioning the integrated circuit proximal to the substrate; aligning the integrated circuit connector terminals with the pads on the substrate using the CCD imagers on the bonding arm; positioning the connector terminals in contact with the pads on the substrate; and performing a solder reflow to attach the integrated circuit to the substrate. An apparatus includes a bonding arm with a chuck for carrying a component and CCD imagers mounted on the arm for alignment.
