laser rapidly emerged as an
ideal source for this application because
it can produce blind vias using a simple,
three-pulse process. The first pulse drills
through the overlying copper, which has
a black oxide coating on it to make it absorb infrared (IR). The second pulse

…to 300µm. They used a 193nm laser wavelength with a 600mJ pulse energy in a maskbased process that produced a fluence of 7J/cm2 at the work surface. The 193nm wavelength was chosen because glass exhibits strong absorption at this wavelength. FIGURE 1. Excimer laser (193nm) vias drilled into glass:…

Picosecond laser marking
With picosecond lasers, the pulse duration
is typically shorter than the time for heat to
flow out of the laser interaction zone, even
in metals, so peripheral thermal effects
are greatly reduced compared to nanosecond lasers. This means that a…
