Abstract
In some embodiments, laser output including at least one laser pulse having a wavelength shorter than 400 microns and having a pulsewidth shorter than 1,000 picoseconds permits the number of pulses used to clean a bottom surface of a via or the surface of a solder pad to increase process throughput. An oscillator module in cooperation with an amplification module may be used to generate the laser output.
