force is used during the operation ball miller

Ball bonding requires only three axes of movement (X,Y,Z) while wedge bonding requires four axes of movement (X,Y,Z,θ). In ball bonding, only gold (Au) wire can be used while gold and aluminum (Al) wires are used commonly in wedge bonding. This is because Al wire will oxidize during the electronic flame off (EFO) process to form the ball.
