  • Patent number: 10960488
    Abstract: A method for operating an ultrasonic wire bonder. The ultrasonic wire bonder has a bonding head with a bonding tool and with a transducer for exciting ultrasonic vibrations in the bonding tool and a controller (2) for the transducer (1). In a first process phase I a bonding wire is bonded to a substrate. The bonding wire is pressed against the substrate with a bonding force via a tool tip of the bonding tool, and the bonding tool is then excited so as to undergo ultrasonic vibrations in order to produce a bond between the bonding wire and the substrate, the transducer (1) being excited so as to vibrate for a specified or variable bonding time. In a second process phase II, the actuation of the transducer (1) is changed and reverberations of the bonding tool are counteracted, the transducer (1) being operated in a damped manner.

  • Patent number: 10940554
    Abstract: Methods of fabricating a probe are described. In an example, a structure may be formed on a surface of a substrate. The structure may include the probe, a hinge, and an anchor arranged linearly, where an angle is formed between the probe and the hinge. The hinge may be positioned between the probe and the anchor, and the structure may be parallel to the substrate. An amount of solder may be deposited on an area of the structure that spans from a portion of the probe to a portion of the anchor, and across the hinge. The deposited solder may be reshaped by an execution of a solder reflow process. The reshape of the deposited solder may cause the probe to rotate about the hinge in order to reduce the angle between the probe and the hinge.
