Study of the Wrinkle Formation in the Heel Zone of Heavy Wire Bonds

Abstract:
This study observes a wrinkling measurement method for non-destructive optical
measurements of deformed bondheels. The wire bonds are manufactured by an ultrasonic wedge/wedge
bonding process. The wire loops are formed with different bending radii, set by the machine parameters
reverse factor and reverse height. The measurement method is based on a modified surface roughness
analysis and was transferred from planar surfaces to the bent heel area of Al heavy wire bonds on nickelplated aluminum. Using this, it is possible to deduce information about damaging and reinforcement processes in the heel.
