  • Method for de-tabbing a disk drive head suspension flexure
    Patent number: 7549211
    Abstract: A method for de-tabbing a dielectric tab extending between and bonded to first and second stainless steel portions of a disk drive head suspension component. Exemplary first and second stainless steel portions are a flexure base region and a flexure tongue. The method includes applying laser energy to the dielectric tab. The laser energy is characterized by one or more parameters, e.g., a pulse width and/or an energy density, causing de-bonding of the dielectric tab from the first and second stainless steel portions.
