How does ultrasonic bonding work
WebWedge bonding technique can be used for both aluminum wire and gold wire bonding applications. The principle difference between the two processes is that the aluminum wire is bonded in an ultrasonic bonding process at room temperature, whereas gold wire wedge bonding is performed through a thermosonic bonding process with heating up to 150oC. … WebDescription. A thermosonic bond is formed using a set of parameters which include ultrasonic, thermal and mechanical (force) energies. A thermosonic bonding machine includes a magnetostrictive or piezoelectric-type transducer which is used to convert electrical energy into vibratory motion which is known as piezoelectricity.The vibratory …
