…highest ablation rate was
found for black rubber with 12 mm3/(W min) at 1035 nm. Materials that were measured but not mentioned
above, were FR4, PEEK, and ivory. For metals, semiconductors and plastics, the optimum average pulse
fluences were in the range of 0.5 - 1.5 J/cm2 for all…

…In volume production, multiple SiP devices are fabricated on a single substrate, typically FR4 or ceramics, which is then cut singulated to yield individual devices. Furthermore, in some cases, trenches are cut into the molding compound in individual devices (before singulation) all the way down to…

…with the shorter
wavelength CO laser.
The most common polymers used for PCBs
are FR4, a fiberglass and epoxy composite.
The CO laser wavelength is well absorbed by
FR4, enabling high efficiency drilling. Use of the
CO laser with other materials depends upon
