PRECISION PROCESSING OF GLASS BY LASER
DESCRIPTION, INNOVATION AND ADVANTAGES
Laser-based techniques such as rear side glass processing can offer high quality and throughput, which can be used for glass drilling, cutting and milling applications. The laser milled feature sizes can be reduced to 150 µm. Laser cuts are taper-less, extremely high aspect ratio features can be fabricated. Laser-based processing can maintain high throughput with the highest processing quality keeping surface chipping below 100 µm.
Materials: soda-lime glass (SLG), fused silica, BK7 glass, borosilicate glass;
Quality: Surface chipping <100 µm, sidewall roughness <2 µm;
Cutting throughput: 0.6 m/min (1 mm SLG glass), 0.12 m/min (5 mm SLG glass);
Via drilling Ø 0.2-1 mm: 1 s/via (1 mm SLG), 5 s/via (5 mm SLG);
Material removal rate: >90 mm3/min.
