  • Patent number: 10930597
    Abstract: Embodiments herein include methods, systems, and apparatuses for die screening using inline defect information. Such embodiments may include receiving a plurality of defects, receiving wafersort electrical data for a plurality of dies, classifying each of the defects as a defect-of-interest or nuisance, determining a defect-of-interest confidence for each of the defects-of-interest, determining a die return index for each of the dies containing at least one of the defects-of-interest, determining a die return index cutline, and generating an inking map. Each of the defects may be associated with a die in the plurality of dies. Each of the dies may be tagged as passing a wafersort electrical test or failing the wafersort electrical test. Classifying each of the defects as a defect-of-interest or nuisance may be accomplished using a defect classification model, which may include machine learning. The inking map may be electronically communicated to an inking system.

  • Patent number: 7670536
    Abstract: Disclosed is a lock of a molding system having a rod and a platen. The lock includes a lock member associated with the rod that is movable between a clamped position and a released position by a clamp assembly. A complementary lock member is associated with the platen. The lock member and the complementary lock member are cooperatively operable to move between a lockable condition and an unlockablecondition within a relatively lower flex zone of the platen. The relatively lower flex zone of the platen is a portion of the platen adjacent to the rod relative to a relatively higher flex zone of the platen also adjacent to the rod.

  • Patent number: 7611346
    Abstract: A clamp actuator of a molding system is provided. The clamp actuator includes a first actuator configured to be interactable with a rod; and a second actuator configured to be interactable with the first actuator. The first actuator is configured to apply a clamping force to the rod; and the second actuator is configured to apply a force opposing the clamping force to the first actuator. Responsive to actuating the first actuator, the rod is drivable between (i) a home position in which a clamping force is not applicable to the rod, and (ii) a force application position in which the clamping force is applicable to the rod. Responsive to a mold flash occurring which exceeds the clamping force, the rod is moveable into a mold flash position beyond the home position.
