DOUBLE LASER DRILLING OF A PRINTHEAD INTEGRATED CIRCUIT ATTACHMENT FILM

摘要

A method of fabricating an apertured polymeric film. The method comprising the steps of: (a) masking a polymeric film with a first mask having first laser transmission zones defined therein; (b) laser-ablatmg first apertures through the polymeric film using the first mask; (c) masking the film with a second mask having second laser transmission zones defined therein, each second zone being aligned with a corresponding first aperture, and each second zone having greater perimeter dimensions than the corresponding first aperture; and (d) reaming the first apertures by laser-ablatmg the polymeric film using the second mask, the reamed first apertures defining second apertures m the film.
