  • Publication number: 20120318850
    Abstract: A chip bonding apparatus includes a chamber, a chip transportation device, a heating device and a ventilation device. The chip transportation device is used for transferring at least one chip onto a carrier within the chamber. The chip transportation device is used for transferring at least one chip onto a carrier within the chamber. The heating device is used for providing heat to the at least one chip and/or the carrier within the chamber. The ventilation device communicates gas to flow through the chamber to form a negative pressure environment therein. The negative pressure environment is provided when the chip transportation device transfers at least one chip onto the carrier within the chamber, and a positive pressure is applied onto the at least one chip when the heating device provides heat to the at least one chip and/or the carrier.
