Abstract: A controller may receive a wire disconnection signal from a wire bonding monitoring system and operate a wire clamp to clamp a disconnected wire. A series of operations, which may include a wire drawing operation, a wire tail forming operation and a ball forming operation, may be automatically performed. A sensor may measure the length of the wire drawn through the capillary and the location of a ball that may be formed at a wire tail. An auxiliary clamp may be installed between the wire clamp and the capillary for drawing the wire using sensor information.

Abstract: A semiconductor wafer, comprising a radio frequency identification (RFID) chip on one side of the semiconductor wafer, on which a pattern has been formed, wherein information on the wafer is input to and/or output from the RFID chip using radio frequency communication.

Abstract: An apparatus and method for wire bonding and die attaching using a system for determining reject frames by determining a z-level distance using a z-axis sensor are provided. The apparatus includes a z-axis sensor that may be moved between a reference position and an upper surface of frames on a PCB; a z-axis sensor controller for positioning and moving the z-axis sensor relative to the frame to measure the z-level distance between the reference position and a z-axis sensor contact position on an upper surface of the frame; and a host controller for determining whether the frame is a reject frame by comparing the measured z-level distance with a reference level. The apparatus and method provides for the dynamic determination of which frames are suitable for additional processing with a low error rate and thereby increase the exclusion rate for reject frames resulting in increased production capacity.

Abstract: A wafer sawing apparatus comprises an electrically conductive chuck table surrounding a suction plate and tactile sensing lines formed on the upper surface of the suction plate. At least one end of each tactile sensing line is electrically connected to the table body. A controller controls the chuck table and a scribing blade. The controller is electrically connected to both elements. The controller comprises a tactile sensing unit connected to the table body for sensing contact of the scribing blade with the tactile sensing lines or the table body and an equipment stop unit for stopping the scribing blade. The controller further comprises a zero point adjusting unit for receiving a contact signal from the tactile sensing unit and for adjusting a zero point of the scribing blade, and a switching unit connecting the tactile sensing unit to the zero point adjusting unit or the equipment stop unit.
