  • Publication number: 20240339430
    Abstract: A bonding system for bonding an electronic component to a base member includes a first container for forming a first inert environment where the base member is locatable during bonding of the electronic component. A first plasma cleaning device is located in the first container to clean the electronic component and/or the base member by removing metal oxides therefrom. A second plasma cleaning device is also provided to clean the electronic component by removing organic contaminants therefrom before the electronic component is conveyed into the first container. A bond head is movably installed in the first container to bond the electronic component to the base member after the electronic component and/or the base member have been cleaned by the first plasma cleaning device.

  • Patent number: 10475763
    Abstract: A die bonding apparatus comprising a first inert gas container having a first inert gas concentration, and a second inert gas container having a second inert gas concentration enclosed within the first inert gas container. The second inert gas concentration is higher than the first inert gas concentration. The die bonding apparatus further comprises a bond head located in the second inert gas container for receiving a die for bonding, and a third inert gas container having an inert gas environment that is separate from the first and second inert gas containers and where a substrate is locatable for die bonding. The bond head is operative to move the die between a first position within the second inert container and a second position within the third inert gas container to bond the die onto the substrate located in the third inert gas container.

  • Patent number: 9281290
    Abstract: A bond head for thermal compression die bonding comprises a collet operative to support a die on a first side of the collet during die bonding and a bond head heater located on a second side of the collet opposite to the first side for heating the collet and the die. A die vacuum suction hole on the bond head heater applies a vacuum suction force to hold the collet, and a collet vacuum suction hole on the bond head heater applies a vacuum suction force to hold the die. At least one vacuum distribution channel that is formed on the second side of the collet is in fluid communication with the collet vacuum suction hole and distributes the vacuum suction force across a surface of the second side of the collet for securing the collet.

  • Patent number: 8857486
    Abstract: An electronic device bonding apparatus comprises a flip arm for picking up an electronic device, the flip arm being operative to invert an orientation of the electronic device. A collet tool which contacts the electronic device and secures it to the flip arm is detachably mountable onto the flip arm, and a bond arm may pick up the electronic device from the collet tool to bond the electronic device to a bonding surface. Additionally, a tool changer module is operative to detach the collet tool from the flip arm and to mount another collet tool onto the flip arm.

  • Patent number: 7667355
    Abstract: A linear motor comprising a coil assembly and a magnet assembly is provided with a cooling apparatus which comprises a segmented air knife assembly. The segmented air knife assembly has a plurality of slot openings distributed along its length which is coupled to the linear motor and it is operative to discharge cooling air into a gap between the coil assembly and magnet assembly in a discharge direction. An inclined surface extends from the plurality of slot openings and slopes at an obtuse angle away from the discharge direction of the cooling air. Each slot opening is individually configured to discharge the cooling air in the discharge direction at a sufficient velocity so as to entrain atmospheric air along the inclined surface to amplify the cooling air that is so discharged.

  • Patent number: 7402778
    Abstract: An oven is provided for curing or reflowing compounds on objects, such as lead frames or other substrates. The oven comprises a heating chamber, a heating assembly mounted in thermal communication with the heating chamber to provide heat thereto, and a support assembly for supporting the object in the heating chamber for heating. The heating assembly and support assembly are configured to be movable relative to one another for controllably positioning the object at variable distances with respect to the heating assembly. Heating of the object according to a heating profile can thus be achieved by controlled heating of the object at different temperatures by positioning the object at different distances with respect to the heating assembly during the heating process although there is a single heating zone.
