ABSTRACT:
A method and apparatus of bonding two electrical members together uses a pulsed YAG laser. Various apparatus and methods may be used to hold the electrical members in contact under pressure to insure uniform bonding. Automation production equipment provides for the automatic bonding of the flat electrical leads of a TAB tape to the flat electrical bumps on a plurality of integrated circuit dies.
