In a flip-chip bonding apparatus, a die inverting device is installed on an optical recognition device so that a vacuum suction chucking nozzle that is provided on the die inverting device can rotate in the direction of a pick-up position and in the direction of a die transfer position in an outside area of an open window of the optical recognition device, so that the bonding apparatus can be compact and has an improved precision of recognition of the amount of positional deviation of the die.

Flip-chip bonding apparatus

A device for preventing wafer rings from being caught on a pair of guide rails of a wafer ring conveying apparatus, including an open-and-close mechanism which moves the pair of guide rails in a closing direction when a wafer ring is supplied onto the guide rails from the wafer ring cassette so as to correct the rotational orientation and/or offset of the wafer ring.

Wafer ring feeding apparatus

A lead frame magazine conveying device including magazine guides that guide the lead frame magazine to be conveyed. The magazine guide comprises a fixed guide and a movable guide which is a bar attached at the end of a swing lever. When the movable guide is brought into contact with one side of the lead frame magazine, the swing lever is tightened by a screw so as not to swing, thus turning the movable guide so as to be immovable, making it possible to smoothly guide the lead frame magazine in cooperation with the fixed guide which is in contact with another side of the lead frame magazine.

Magazine conveying device

A lead frame magazine conveying device including vertically provided magazine loader and unloader sections and an elevator system which transfers the lead frame magazine between the magazine loader and unloader sections after bringing the magazine to lead frame receiving or feed out positions. The conveying device further includes a magazine pressing assembly which presses and corrects the attitude of the magazine in the elevator so that the elevator can move the magazine after its attitude is corrected properly by the magazine pressing assembly.

A lead frame pusher device for feeding lead frames in and out of a lead frame magazine including: a pusher mount installed between a pair of lead frame supply guide rails so that the pusher mount can travel along the supply guide rails, a pusher driver which moves the pusher mount along the supply guide rails, a first pusher fastened to the pusher mount so as to project upward from the pusher mount, a second pusher fastened to the pusher mount so as to be located below the first pusher and extends toward the magazine, and a pusher driver for vertically moving the pusher mount so that the first and second pushers are moved to a lead frame conveying path level of the lead frame supply guide rails.

Lead frame pusher device

A lead frame magazine conveying device including vertically provided magazine loader and unloader sections and an elevator system which transferred the lead frame magazine between the magazine loader and unloader sections, and the conveying device further including a a shutter that is movable back and forth so as to come into contact with or close to a magazine which has been transferred onto the magazine unloader section, thus preventing the magazine from falling over and from dropping from the magazine unloader section.

A pellet pick-up device including a wafer sheet stretching structure that includes a vertical driving assembly which raises and lowers the wafer sheet stretching ring and includes synchronously driven first and second motors which raise and lower portions of the wafer sheet stretching ring that are symmetrical with respect to the center of the wafer sheet supporting ring.

Pellet pick-up device

A dispenser apparatus for dropping paste onto a substrates, etc. including a syringe having a nozzle, a motor which moves the syringe up and down, a controller which controls the rotational stopping positions and rotational speed of the motor, and digital switches for inputting a setting program into the controller. The setting program sets the rotational stopping positions and rotational speed of the motor so that the position at which lowering of the nozzle stops and the speed at which the nozzle is raised are controlled through the setting program.

Dispenser apparatus

A wafer supplying apparatus including a supply ring to which a wafer sheet having semiconductor pellets adhered thereto is attached, a ring holder provided on an X-Y table of a pellet pick-up device, the ring holder supporting and placing the wafer sheet onto the upper surface of a cylindrical portion of the ring holder having an external diameter smaller than the internal diameter of the supply ring, a pressing ring provided above the supply ring, a pusher which pushes down the supply ring around the cylindrical portion of the ring holder through the pressing ring, and a fastener which fastens the pressing ring to the ring holder after the supply ring has been pushed down by the pusher.
