Patent ID: 7735716

Claim:
A method of determining a trajectory of an arc motion of a wire used in the formation of a wire loop, the arc motion being between a first point and a second point of the trajectory, the method comprising the steps of: (1) defining a pivot point with respect to the first point and the second point, the first point including a first radius value and a first angle value, the first radius value being between the pivot point and the first point, the first angle value being defined by the pivot point and the first point, the second point including a second radius value and a second angle value, the second radius value being between the pivot point and the second point, the second angle value being defined by the pivot 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 determined using at least one time based function, each of the angle values being between (a) the first angle value, and (b) the second angle value; and (3) converting the plurality of data points, including the first point and the second point, into trajectory data that may be used by a wire bonding machine.
