Ultrasonic bonding process

摘要

A method for bonding a metal wire (17) to a metal bond site (16) utilizes an ultrasonic power source (12) that is at approximately 162 KHz. A mash force is applied from a pressure source (13) during bonding. A metal exchange takes place between the metal wire (17) and the bond site (16) during the application of the ultrasonic power to produce a strong bond between the metal wire (17) and the bond site (16).
