It is an object to enable a non-destructive inspection of reliability of a bonding part and enabling an accurate inspection. A wedge tool includes: a groove which is formed along a direction of an ultrasonic vibration in a tip portion and in which a bonding wire is disposed in a wedge bonding; a first planar surface and a second planar surface disposed on both sides of the groove; and at least one convex portion formed away from the groove in at least one of the first planar surface and the second planar surface, wherein the bonding wire comes in contact with the convex portion by a deformation of the bonding wire in a bonding part of the bonding wire and a bonded object bonded to each other by a wedge bonding.

A method of determining a shear strength of a bonded free air ball on a wire bonding machine is provided. The method includes the steps of: (a) providing a free air ball at a working end of a wire bonding tool; (b) bonding the free air ball to a bonding location of a workpiece; (c) moving the wire bonding tool, while in contact with the bonded free air ball, in a direction along the bonding location; (d) monitoring wire bonding process signals during step (c); and (e) determining a shear strength using the wire bonding process signals monitored in step (d).

A multifaceted capillary that can be used in a wire-bonding machine to create a multi-segment wire-bond is disclosed. The multifaceted capillary is shaped to apply added pressure and thickness to an outer segment of the multi-segment wire-bond that is closest to the wire loop. The added pressure eliminates a gap under a heel portion of the multi-segment wire-bond and the added thickness increases a mechanical strength of the heel portion. As a result, a pull test of the multi-segment wire-bond may be higher than a single-segment wire-bond and the multi-segment wire-bond may resist cracking, lifting, or breaking.

The invention relates to a bonding arrangement comprising a bonding tool including a tool shank, which is designed as elongated in a tool longitudinal direction, and including a tool tip, which adjoins the tool shank, and comprising a light guide designed to conduct a laser beam, the light guide being provided in a longitudinal recess of the bonding tool, the longitudinal recess extending from an end face of the bonding tool opposite the tool tip in the direction of the tool tip, a functional recess being formed on the lateral surface of the bonding tool, and the longitudinal recess being made to extend up to the functional recess. The invention further relates to a bonding tool having a functional application as well as the use of the bonding arrangement according to the invention and/or the bonding tool for ultrasonic bonding.

A wedge bonding tool including a body portion including a tip portion is provided. The tip portion includes a working surface configured to contact a wire material during formation of a wedge bond. A plurality of notches are defined by one or more surfaces of the body portion.

Bonding device for producing bonding connections, in particular wire bonding connections, tape bonding connections and ball bonding connections, on carriers fixed outside the bonding device and having contact surfaces for the bonding connections, in different spatial directions with respect to the respective carrier, the bonding device comprising a base body, a bonding tool which is movable relative to the base body for applying a bonding force to a bonding means placed on the contact surface of the carrier to produce a material bond between the bonding means and the contact surface as a bonding connection, and bonding force generating means for generating a bonding force directed towards the contact surface when the bonding tool is placed on the carrier, wherein the bonding force generating means comprise a bonding force setting device for realizing a predetermined effective bonding force independently of its spatial direction of action.
