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.

Abstract:
In a method of detecting faults of operation algorithms in a wire bonding machine, individual bond parameters with respect to each of the operation algorithms of the wire bonding machine can be set based on design data including information with respect to conductive wires connected between semiconductor chips of a semiconductor package. Actual conductive wires of an actual semiconductor package can be formed using the wire bonding machine into which the design data can be inputted. Actual data with respect to actual operation algorithms of the wire bonding machine, which can form the actual conductive wires, can be obtained. The actual data can be compared with the individual bond parameters to detect the faults of the operation algorithms of the wire bonding machine. Thus, forming an abnormal conductive wire by the wire bonding machine can be prevented beforehand.
