Multiple laser wavelength and pulse width process drilling










Image Number 10 for United States Patent #8116341.

Dual-beam laser outputs, preferably derived from a single laser beam, improve the quality of the sidewalls of vias drilled in a target material, such as printed circuit board, comprising fiber-reinforced resin. Two embodiments each use two laser output components to remove a portion of target material from a target material location of a workpiece and rapidly clean remnants of the target material bonded to a metal layer underlying the target material location at a material removal rate. A first embodiment entails directing for incidence on a portion of the target material at the target material location a processing laser output having first and second components characterized by respective first and second wavelengths. A second embodiment entails directing for incidence on a portion of the target material at the target material location a processing laser output having first and second components characterized by respective first and pulse widths.
