  • Apparatus for aligning a bonding tool of a die bonder
    Patent number: 8387851
    Abstract: An apparatus for aligning a bonding tool of a die bonder with respect to a bond stage is disclosed. The apparatus comprises: a connecting member to which the bonding tool is coupleable such that the connecting member is located between the bonding tool and a main body of a die bonder; and a plurality of actuators engaged to the connecting member. In particular, the plurality of actuators are actuable to rotate the connecting member and the bonding tool relative to the main body of the die bonder about a plurality of axes, to align the bonding tool with respect to the bond stage.

  • Apparatus for improved fiber optic coupling efficiency
    Patent number: 7254296
    Abstract: An optical assembly incorporates a compact and efficient lens for coupling a beam of light from an optical device to an optical fiber. The lens includes a curved reflecting surface and a focusing surface. The lens is positioned to receive and internally reflect the beam of light from the optical device toward the focusing surface. The focusing surface in turn focuses the reflected beam into the end of an optical fiber. The curved surface may include a reflective coating for transmitting a portion of the beam toward a monitoring unit which is used to monitor a parameter of the beam. The optical assembly may further include a platform for supporting the optical device, the lens, the optical fiber and the monitoring unit.
