…must fulfill very tight tolerances (50 µm diameter vias in resin-coated copper (RCC), Fr4 and aramid-based dielectrics, as well as Cu-direct drilling processes. The AVIA-series diode-pumped UV lasers are ideal for drilling <70 µm diameter vias in RCC and PTFE-based dielectrics and copper. Related…

…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 drills
through the glass resin board substrate material, which…

…silicon or glass.
Critical to the production of the interposer is
the creation of small through holes, called vias,
which are used to make electrical connections
between the circuit components. Target via
diameters are usually in the 25 µm size range.
These vias can be…

…and
substrate wafers are well-suitable [3].
In a final step, the glass carrier is released
from the finished thin wafer via laser
lift-off. To this end, the excimer laser is
shown through the glass wafer and selectively evaporates the most adjacent fraction of polymer film.…

…The robot arm picks up the windscreen using vacuum
suction. Correct, adhesive-fixed installation requires correct orientation of the
glass in several axes and dimensions, e.g., tilt, rotation, XY, etc. The current
practice here is to project a small line across the gap between…

…process is conducted with a 308
nm excimer laser. UV lasers work via a cold process
very much different from infrared lasers.
IR lasers penetrate far into the adhesive layer and
easily cause debonding through a thermal mechanism
(e.g. heating). Oxide layers are put into the…
