Chanxan provides advanced laser processing solutions for technical glass (UTG, quartz, borosilicate, OLED). Non-contact precision cutting & micro-drilling ensures zero micro-cracks, no thermal scars, and maximum edge strength. Request a tech solution today.
High-transparency, thermally sensitive glass — UTG, quartz, borosilicate, aluminosilicate, and OLED glass — demands a laser process that never touches the surface with a blade and never leaves a heat scar behind.
Ultra-thin glass (UTG) used in foldable displays is often thinner than a human hair. Mechanical stress at the edge propagates into micro-cracks that only show up after hundreds of fold cycles.
Borosilicate and aluminosilicate glass has a narrow thermal processing window. Excess heat input creates residual stress that later shows up as warping or spontaneous cracking.
For camera modules and AR/VR optics, any debris, micro-chipping, or haze along the cut edge is visible in the final optical path and fails inspection.
Camera modules and sensor windows require through-holes and blind vias at diameters far below what mechanical drilling can achieve without cracking the surrounding glass.
A cold, non-contact cutting process separates the glass sheet along the target contour without introducing mechanical load, keeping edge strength close to the bulk material's rating.
Fine through-holes and blind vias are formed for camera windows, sensor apertures, and connector access points, with hole taper and edge chipping held within tight tolerances.
A focused beam is used to create modification layers inside the glass volume without breaking the surface — the basis for controlled internal separation.
After separation, the edge profile is refined to remove micro-chipping and smooth the contour, which determines fold-cycle durability.
A shallow scribe line defines a controlled fracture path for high-volume panel singulation, useful where downstream breaking equipment is integrated.
Microscopic processing results showing clean edges, zero heat scars, and precise geometry control.
These are the segments where Chanxan laser systems are actively deployed for technical glass laser processing.
