  • Patent number: 11791197
    Abstract: A die bonding system comprising a wafer lift and level assembly configured to allow rapid planarization of a wafer comprising a wafer frame configured to retain a wafer and be slidably retained within guide clevises and a leveling pedestal configured to support a wafer from below in a localized area where a die bonding operation is to take place, allowing the quick and repeatable planarization of die(s) to the wafer without the need for distinct planarization procedures that would slow cycle times and decrease production.
    Type: Grant

  • Patent number: 9911710
    Abstract: Co-planarity adjustment systems and methods, gantries capable of applying high force without imposing moment loads to their bearings, systems and methods for achieving rapid heating and cooling and efficient slidable seal systems capable of sealing a chamber and injecting one or more fluids into the chamber as well as actively recovering portions of such fluid which have migrated into the seal itself are disclosed in the context of thermo-compression bonding systems, apparatuses and methods, although many alternative uses will be apparent to those of skill in the art.

  • Publication number: 20150380379
    Abstract: A system and method are provided for enabling the production of semiconductors requiring very high precision thermo-compression bonding, the system comprising a thermo-compression bonding system having force and/or distance measuring sensors configured to sense thermal expansion of system components and a controller configured to counteract such expansion by exercising appropriate control over such system. This system and method may be used for both constant force profile applications as well as those requiring variable force during a bonding operation.

  • Publication number: 20050072815
    Abstract: A dispensing apparatus has a motor drive that moves an output member along an axis in a first chamber. A shuttle valve controls flow between a first chamber and either a reservoir of material or an output port. Extending the output member discharges precise volumes of material through an output port. Retracting the output member fills the first chamber.

  • Publication number: 20050045914
    Abstract: A flip chip assembly machine (FCAM) (30) includes a main gantry (50) and a substrate camera gantry (40) that are configured to operate independently of each other and, respectively, support a die (12) and a substrate camera (38) for alignment purposes. The FCAM further includes a fluxer (130) for applying flux to the die. A flip-to-flux pick and place subassembly (116) picks up a die and places it in flux (46) independently of the operation of the main gantry, which may perform another task during the flux dwell time. A substrate carrier conveyor (154) includes a walking beam (260) to rapidly accelerate and decelerate substrate carrier movement into and out of the FCAM.

  • Patent number: 6389688
    Abstract: A method and apparatus for accurately registering electronic chip bonding pads with substrate leads. Images are developed of different portions of the interface between the electronic chip and the substrate by reflecting collimated, parallel light from the bottom of the chip through transparent areas of the substrate. Image analysis of the composite, superimposed images from spaced positions containing the bonding pads and the leads provide a corrective positioning after which the electronic chip and substrate are brought into contact.

  • Patent number: 6220487
    Abstract: A dispensing pump includes first and second sleeve assemblies. Each sleeve assembly includes a rotary valve having an input and output position and a longitudinally displaceable piston that moves between a first position abutting the valve and a second position displaced from the valve. The sleeve connects to a manifold with input and output passages that align with input and output apertures in the sleeve. Withdrawing the piston with the input port of the valve aligned with the input aperture draws material into the sleeve. Moving the piston toward the valve in the output position with the output port aligned with the output passage displaces material from the manifold.
