The modular TGD platform and the lablator HP platform

Share this on social media:

4JET Technologies has introduced two laser systems for processing touch panel displays. The modular TGD platform can handle individual cells or wafers up to entire Gen 5.5 substrates, and performs drilling of microphone and speaker slots as well as home buttons or camera glasses.

Equipped with diode-pumped solid-state lasers and proprietary process optics, the TGD allows the user to create non-contact laser drilling of soda lime, sapphire or chemically strengthened glass. Two drilling modules work in parallel for high throughput. The TGD can also drill into coated glass, create hole diameters below 1mm, and shape chamfers.

The second product is the Lablator HP platform for selective patterning of transparent conductive films such as ITO or silver nano wires, metals and inks. It can pattern both glass and PET substrates at line speeds exceeding 2m/s. The platform can create narrow pitched and fine scribes with 20µm width and 20µm pitch, enabling higher density of silver circuits in the display edge and an almost invisible grid in the touch sensor. It has an unlimited scanfield option for the processing of devices larger than the conventional working area of laser scanheads, a DXF to G-Code conversion and a modular design enabling integration of sheet-to-sheet or roll-to-roll automation.
