Laser Glass Drilling
Micro-hole, hole-array and local opening processing for technical glass and fused quartz.
Laser drilling suits glass parts that need non-contact processing, smaller hole diameters, complex hole arrays or geometries unsuited to conventional mechanical drilling. Process selection must consider glass type, thickness, hole diameter, hole spacing, taper, edge heat effect and downstream cleaning requirements.
Engineering Focus of Laser Drilling
For brittle glass, drilling a hole is not just about punching through. The entry and exit edges, hole wall condition, taper, micro-cracks, heat-affected zone and debris all affect subsequent assembly, sealing, metallisation or cleaning.
For hole arrays, hole diameter, pitch, position datum and overall warpage must be considered together. For fused quartz and thin glass, the laser mechanism must be matched to the material's absorption characteristics and thickness.
