Abstract: A reflow apparatus include a carrier supporting a printed circuit board placed on a side thereof by using a vacuum pressure generated therein, and a processing chamber including a heating chamber and a cooling chamber, wherein the carrier includes at least one adsorption hole, formed in one side of the carrier, a vacuum space connected to the adsorption hole, and a vacuum control unit capable of maintaining or removing a vacuum pressure in the vacuum space by selective opening and closing a path connecting the vacuum space to the outside.

Abstract: A chip mounting apparatus includes a loading unit, a combining unit and a bonding unit. The loading unit loads a circuit board having contact pads and semiconductor chips having solder balls into the chip mounting apparatus. The combining unit positions the semiconductor chip onto a respective mounting area of the circuit board and combines the solder balls of the semiconductor chip with the contact pads of the circuit board by using flux. The combining unit has a flux coater for coating the solder balls with the flux and a flux controller for automatically supplementing the flux to the flux coater. The bonding unit bonds the solder balls to the respective contact pads by a reflow process.
