Apparatus and method for mounting components on a substrate
The invention relates to an apparatus for mounting components on a substrate. The apparatus comprises a bond head with a component gripper, a first drive system for moving a carrier over relatively long distances, a second drive system which is attached to the carrier for moving the bond head back and forth between a nominal working position and a stand-by position, a drive attached to the bond head for rotating the component gripper or a rotary drive for rotating the substrate about an axis, at least one substrate camera attached to the carrier and at least one component camera. Either the second drive system is also designed to perform high-precision correction movements with the bond head, or a third drive system is provided to perform high-precision correction movements with the substrate. At least one reference mark is attached to the bond head or the component gripper.
Method for transfer of semiconductor devices onto glass substrates
A method for transferring a plurality of die operatively associated with a transfer apparatus to a glass substrate to form a circuit component. The transfer occurs by positioning the glass substrate to face a first surface of a die carrier carrying multiple die. A reciprocating transfer member thrusts against a second surface of the die carrier to actuate the transfer member thereby causing a localized deflection of the die carrier in a direction of the surface of the glass substrate to position an initial die proximate to the glass substrate. The initial die transfers directly to a circuit trace on the glass substrate. At least one of the die carrier or the transfer member is then shifted such that the transfer member aligns with a subsequent die on the first surface of the die carrier. The acts of actuating, transferring, and shifting are repeated to effectuate a transfer of the multiple die onto the glass substrate.
CHIP CONVEYING APPARATUS AND DIE BONDER
A conveying unit for conveying a device chip onto a predetermined electrode of a board has a chip chuck that holds under suction one surface of the device chip, a support base to which the chip chuck is fixed in an inclinable manner, and a moving unit that moves the support base, in which a fixing mechanism that fixes the chip chuck to the support base has a plurality of leaf springs extending laterally radially from the chip chuck, the plurality of leaf springs are connected to the support base in the surroundings of the chip chuck, and the plurality of leaf springs are pulled one another, so that the chip chuck is supported in air in an inclinable manner.
Bonder
A bonder includes a first chuck unit 1A, a second chuck unit 1B, a first base 21A, a second base 21B, and a first floating mechanism 3A. The first chuck unit 1A and the second chuck unit 1B are chuck units in a pair including respective suction surfaces for suction of bonding targets and are arranged while respective suction surfaces 11a and 11b face each other. The first base 21A and the second base 21B support the first chuck unit 1A and the second chuck unit 1B respectively. The first floating mechanism 3A applies gas pressure to a back surface 12a of the first chuck unit 1A to float the first chuck unit 1A from the first base 21A, thereby moving the suction surface 11a of the first chuck unit 1A toward the suction surface 11b of the second chuck unit 1B.
Die bond head apparatus with die holder motion table
A die bond head apparatus has a die bond head body coupled to a die bond head motion table, a die holder motion table mounted on the die bond head body and a die holder which is operative in use to secure a semiconductor die to a substrate. The die holder is positionable by the die holder motion table independently of the die bond head motion table.

Direct transfer of semiconductor devices from a substrate
A method includes loading a wafer tape into a first frame, the wafer tape having a first side and a second side, a first semiconductor device die being disposed on the first side of the wafer tape. A substrate is loaded into a second frame, the substrate including a second semiconductor device die onto which the first semiconductor device die is to be transferred. A needle is oriented to a position adjacent to the second side of the wafer tape, the needle extending in a direction toward the wafer tape, and a needle actuator connected to the needle is activated to move the needle to a die transfer position at which the needle contacts the second side of the wafer tape to press the first semiconductor device die into contact with the second semiconductor device die.

Method for improved transfer of semiconductor die
A system to effectuate improved transfer of semiconductor die. A first frame secures a first substrate having the semiconductor die. A second frame secures a second substrate adjacent the first substrate. A needle is disposed adjacent to the first frame. The needle includes: a longitudinal surface extending in a direction toward the second frame, and a base end having a cross-sectional dimension being based, at least in part, on a cross-sectional dimension of the semiconductor die. A needle actuator is operably connected to the needle and is configured to actuate the needle such that, during the transfer operation, when the first substrate is secured in the first frame and the second substrate is secured in the second frame, the needle presses the semiconductor die into contact with the second substrate so as to transfer the semiconductor die onto the second substrate.
