  • Method for mounting an integrated circuit from a tape carrier package on a printed circuit board
    Patent number: 6138892
    Abstract: A method for mounting an integrated circuit having a plurality of leads on a PCB. In order to mount the integrated circuit having a plurality of leads on the PCB, foreign substance on the PCB is first removed and a flux is simultaneously spread over the lead patterns formed on the PCB. After that, by aligning the leads of the integrated circuit with lead patterns on the PCB on which the flux is spread, some leads of the integrated circuit is temporarily fixed to the corresponding lead patterns of the PCB. After soldering the leads of the integrated circuit to the lead patterns of the PCB by radiating an optical beam on the entire whole surface, the soldered PCB is cooled, thereby mounting the integrated circuit on the PCB.
