  • Particle removing vacuum system for assembly of FBGA packages
    Patent number: 6474355
    Abstract: The present invention provides a method and system for blowing dust and other foreign particles off semiconductor substrate surfaces. The system may blow ionized air, which neutralizes electrostatic charges on the substrate surface thereby facilitating the release of particles from the substrate and reducing the risk of damage to semiconductor substrates from electrostatic discharge. The system also provides a vacuum for capturing dust particles blown off the surface, thus preventing the particles from contaminating clean room environments and redepositing on the cleaned substrate or other substrates.
