…and wire bonding. For defective parts, the
gold pad is marked by converting its color from gold to
black or to dark grey.
Ideally, it is desirable to have one laser marker that
can accomplish all three of these marking applications
tasks. The green DPSS laser has become the…

window for crack free marking. It can be used with
pulse energies of 40 to 60 µJ at beam diameters of
about 20 µm. The visibility of the color marks can be
varied over a wide range by choosing the proper laser
parameters.

…picosecond laser marking, which can produce marks that involve either a color change or a slight alteration in surface relief, essentially without any HAZ and negligible surface modification. Another example of high value marking is the production of bar codes and other marks on the sapphire wafers…

…for
pharmaceuticals. These marks were created with a
depth of 30% (0.17 mm of 0.58 mm thickness) with a
scan speed of 1.3 m/s. The color change marks show
good contrast with no material ablation.
Summary
In summary, UV laser marking is shown to be a
superior…

"color
marking," because the marks exhibit a rainbowlike color
effect when viewed under the proper lighting. Color
marking actually involves ablating just a few nanometers of material from the surface of a glass or sapphire
substrate. Here, it is essential that the marking

…into the metal surface and creates the desired contrast.When
marking plastics, the exact color of the mark is highly dependent
on the additives found in the plastic. If a high quality mark with
high contrast or color change is required, a 1 m, 532 nm or 355 nm
wavelength from the…
