METHODS OF OPERATING A WIRE BONDING MACHINE TO IMPROVE CLAMPING OF A SUBSTRATE, AND WIRE BONDING MACHINES
A method of operating a wire bonding machine is provided. The method includes the steps of: (a) supporting a substrate on a material handling system of the wire bonding machine; (b) changing a bend profile of the substrate; and (c) securing, after step (b), the substrate against a support structure of the wire bonding machine using a clamping element of the wire bonding machine, the support structure for supporting the substrate during a wire bonding operation, and the clamping element for securing the substrate to the support structure during the wire bonding operation.
Bonding apparatus and alignment method
A bonding apparatus includes: a clamper able to clamp a wire between a pair of arms; a horn, in which a first through hole able to hold a capillary, and a second through hole adjacent to the first through hole and penetrating the horn in an up-down direction are further formed; and a bonding stage able to carry a workpiece. An alignment method for aligning a horn and a damper of a bonding apparatus with each other includes: disposing a mirror surface to be parallel to a bonding stage; aligning a mirror image of a second through hole reflected on the mirror surface with a center of the second through hole when the mirror surface is viewed through the second through hole; and aligning the damper based on a position of the mirror image and the horn.
METHOD FOR DETERMINING STATE-RELATED INFORMATION, FOR EXAMPLE WEAR-RELATED INFORMATION, CONCERNING AN ULTRASONIC WELDING DEVICE
A method for determining condition information for an ultrasonic welding device. The condition information specifies information about the current condition of at least one component of the ultrasonic welding device. The ultrasonic welding device includes, as components, a sonotrode, an anvil, a touching element and/or a lateral slide as well as a receiving chamber defined by the components.
Ultrasonic tool and ultrasonic connection device herein
An ultrasonic tool comprising a first end face and a second end face, which is opposite the first end face, as well as a tool cover surface connecting the first end face and the second end face, wherein the ultrasonic tool is elongated in a longitudinal direction of the tool, wherein at least the first end face is formed as a connecting contact surface, which is arranged for pressing the ultrasonic tool against a connecting component, and wherein the ultrasonic tool comprises an end region comprising the connecting contact surface, which extends from the connecting contact surface in the longitudinal direction of the tool over 15 mm, but at most extends one third of the length of the ultrasonic tool in the direction of the opposite end face, and wherein in the end region, a first partial surface of the tool cover surface is formed as a surface-structured absorption surface.
Al bonding wire
There is provided an Al bonding wire which can provide a sufficient bonding reliability of bonded parts of the bonding wire under a high temperature state where a semiconductor device using the Al bonding wire is operated. The bonding wire is composed of Al or Al alloy, and is characterized in that an average crystal grain size in a cross-section of a core wire in a direction perpendicular to a wire axis of the bonding wire is 0.01 to 50 ?m, and when measuring crystal orientations on the cross-section of the core wire in the direction perpendicular to the wire axis of the bonding wire, a crystal orientation <111> angled at 15 degrees or less to a wire longitudinal direction has a proportion of 30 to 90% among crystal orientations in the wire longitudinal direction.
Wire bonding apparatus, method for measuring opening amount of clamp apparatus, and method for calibrating clamp apparatus
A wire bonding apparatus of an aspect includes: a clamp apparatus, having a pair of arms; a stage, moving the clamp apparatus in a horizontal direction; a rod member; a contact detection part, detecting contact between the rod member and the clamp apparatus; and a control apparatus, controlling opening and closing of the pair of arms and an operation of the stage and acquiring position information of the clamp apparatus. The control apparatus obtains an opening amount of the pair of arms based on position information of the clamp apparatus at a time when an outer side surface of a first arm contacts the rod member in a state where the pair of arms are closed and position information of the clamp apparatus at the time when the outer side surface of the first arm contacts the rod member in a state where the pair of arms are open.
WIRE TENSION ADJUSTMENT METHOD AND WIRE TENSION ADJUSTER
Provided is a wire tension adjuster (60) that adjusts tension (T) applied to a wire (18) of a wire bonding apparatus (100). In the wire tension adjuster (60), in a state in which the wire (18) is gripped by a wire clamper (17), air is supplied to a wire tensioner (40) and a height position (H) of a tip (14f) of a bonding arm (14) is detected, and a flow rate (G) of the air supplied to the wire tensioner (40) is adjusted based on the height position (H) detected, thereby adjusting the tension (T) applied to the wire (18).
