9 Car window traceability using datamatrix codes AUTOMOTIVE The customer requested a laser marking solution able to grant effective traceability of car window glasses (floating glass) by using datamatrix codes. Perfect readability of the code through the entire production process (including temper), together with unaffected mechanical properties of the glass, are fundamental requirements. The customer asked us to find the best solution choosing among a CO 2 laser, a green laser and an UV laser. The maximum amount of marking time was 5 seconds. DLA s UV-Lase was found to be the best marking solution to meet the customer requirements. Unlike infrared and green light, UV light marks the datamatrix inside the glass, thus making it permanent through all the following treatments. Moreover, the glass does not lose its mechanical characteristics (e.g. resistance to tensile stress). UV-Lase nm F-theta = 100 mm marking time < 5 s 2D resolution: 12 mils, 7 mils, 4 mils

10 Glass Substrate Traceability on Solar Cells SOLAR Traceability through datamatrix codes, alphanumerical codes, or both, is highly recommended in solar cells glass substrate production. But laser marking on one side of the panel might affect also its opposite side, where a very thin TIN coating is applied. Thus accurate and selective laser marking is required. When DLA s UV-Lase laser marker is adjusted to focus on the uncoated side, there is no effect on the opposite side of the thin glass substrate. Since traceability marking requires small sizes, a marking speed between 50 mm/s and 150 mm/s provides high throughput, depending on fonts and graphics.
