  • Patent number: 8302840
    Abstract: A method of applying bonding energy to form a bond between a portion of a wire and a contact of a bonding location using a wire bonding machine is provided. The method includes: (1) moving a bonding tool towards the contact; (2) detecting when a portion of the contact (100a) is pressed against a device supporting surface (112) of the wire bonding machine; and (3) applying bonding energy to the portion of the contact such that a bond is formed between the contact and the portion of wire.

  • Patent number: 7735716
    Abstract: A method of determining a trajectory of an arc motion of a wire used in the formation of a wire loop is provided. The arc motion is between a first point and a second point of the trajectory. The method includes: (1) defining a pivot point with respect to the first point and the second point; (2) determining a plurality of data points for generating the trajectory, each of the data points including a radius value and an angle value as a function of time, each of the angle values being between (a) a first angle defined by the pivot point and the first point, and (b) a second angle defined by the pivot point and the second point; and (3) converting the plurality of data points into trajectory data that may be used by a wire bonding machine.
