Abstract

A chip mounting system includes a substrate supply apparatus and a chip supply apparatus. The substrate supply apparatus includes a transport conveyor formed to be moved for a length corresponding to the size of a discrete substrate and a stage with a disposition surface corresponding to the size of the discrete substrate. In the chip supply apparatus, the lowermost chip tray of a plurality of stacked chip trays is sequentially transported to a chip supply stage, and a tray stage is disposed near the chip supply stage. In addition, the chip supply apparatus includes a box for surrounding an area in which the substrate and the chip are transported as a substantially closed space and a clean fan for flowing clean air into the closed space.

Claims (40)

1. A method of supplying a substrate in a chip mounting apparatus, the method comprising:

transporting a substrate to a position above a stage via a conveyor;

moving the conveyor and stage toward each other so that the stage removes the substrate from the conveyor and supports the substrate above the conveyor for chip mounting; and

maintaining a volume around the stage with a positive air pressure to maintain a clean environment.

2. A method of supplying a substrate in a chip mounting apparatus, the method comprising:

transporting a substrate to a position above a stage via a conveyor; and

moving the conveyor and stage toward each other so that the stage removes the substrate from the conveyor and supports the substrate above the conveyor for chip mounting,

wherein the movement of the conveyor and stage toward each other is provided by movement of the conveyor while the stage remains stationary.

3. A method of supplying a substrate in a chip mounting apparatus, the method comprising:

transporting a substrate to a position above a stage via a conveyor; and

moving the conveyor and stage toward each other so that the stage removes the substrate from the conveyor and supports the substrate above the conveyor for chip mounting,

wherein the conveyor is of a concave shape with a through hole in a bottom surface thereof, so that the concave shape supports a perimeter of the substrate and the through hole allows passage of a portion of the stage.

4. A method of supplying a substrate in a chip mounting apparatus, the method comprising:

transporting a substrate to a position above a stage via a conveyor;

moving the conveyor and stage toward each other so that the stage removes the substrate from the conveyor and supports the substrate above the conveyor for chip mounting; and

activating a stopper to stop the movement of the substrate when it reaches a position above the stage.

5. The method of supplying a substrate in a chip mounting apparatus, the method comprising:

removably holding the substrate in a substrate carrier; transporting the substrate carrier to a position above a stage;

moving the substrate carrier and stage toward each other so that the stage removes the substrate from the substrate carrier and supports the substrate above the substrate carrier for chip mounting; and

maintaining a volume around the stage with a positive air pressure to maintain a clean environment.

6. The method of supplying a substrate in a chip mounting apparatus, the method comprising:

removably holding the substrate in a substrate carrier;

transporting the substrate carrier to a position above a stage; and

moving the substrate carrier and stage toward each other so that the stage removes the substrate from the substrate carrier and supports the substrate above the substrate carrier for chip mounting,

wherein the movement of the substrate carrier and stage toward each other is provided by movement of the substrate carrier while the stage remains stationary.

7. The method of supplying a substrate in a chip mounting apparatus, the method comprising:

removably holding the substrate in a substrate carrier;

transporting the substrate carrier to a position above a stage; and

moving the substrate carrier and stage toward each other so that the stage removes the substrate from the substrate carrier and supports the substrate above the substrate carrier for chip mounting,

wherein the movement of the substrate carrier and stage toward each other is provided by movement of the stage while the substrate carrier remains stationary.

8. The method of supplying a substrate in a chip mounting apparatus, the method comprising:

removably holding the substrate in a substrate carrier;

transporting the substrate carrier to a position above a stage; and

moving the substrate carrier and stage toward each other so that the stage removes the substrate from the substrate carrier and supports the substrate above the substrate carrier for chip mounting,

wherein the substrate carrier is of a concave shape with a through hole in a bottom surface thereof, so that the concave shape supports a perimeter of the substrate and the through hole allows passage of a portion of the stage.

9. The method of supplying a substrate in a chip mounting apparatus, the method comprising:

removably holding the substrate in a substrate carrier;

transporting the substrate carrier to a position above a stage;

moving the substrate carrier and stage toward each other so that the stage removes the substrate from the substrate carrier and supports the substrate above the substrate carrier for chip mounting; and

activating a stopper to stop the movement of the substrate when it reaches a position above the stage.
