Can laser glass drilling machines process ultra-thin glass?
The delicate relationship between laser glass drilling machines and ultra-thin glass
0~3 times. You may have heard of the widespread application of laser drilling technology in glass processing, especially the good reputation of brands like Prologis in the industry. But when faced with ultra-thin glass less than 100 micrometers thick, can laser drilling machines really handle it easily?
Definition and challenges of ultra-thin glass
Surprisingly, ultra-thin glass—generally referring to thicknesses between 50 and 200 micrometers—due to its fragility, is much more difficult to process than ordinary glass a few millimeters thick. For example, Corning Gorilla Glass 5 and AGC Dragontrail are both toughened glasses with high hardness, but their extreme thinness makes them prone to cracks or breakage caused by the heat-affected zone (HAZ) during laser processing.
Working principle of laser drilling machines and their suitability for thin glass
Prologis's glass laser drilling machines adopt femtosecond laser technology, whose ultra-short pulse duration results in minimal heat input, reducing thermal damage—a key advantage. However, process parameters must be precisely adjusted: power, frequency, and scanning speed all need to match the characteristics of ultra-thin glass. Otherwise, even slight overheating can cause cracks at the edges—this is no small matter!
Case analysis: Prologis 0~3 experiments results
- Ultra-thin glass samples with a thickness of 70 micrometers processed by Prologis's laser drilling machine, with hole diameters precisely controlled within 100 micrometers.
- Processing speed increased by 30%, with no obvious cracks, indicating excellent equipment stability.
- However, if not adjusted properly, even a 10% reduction in power can cause micro-cracks at the edges of the holes.
This precise operation, akin to 'art on the edge of a knife,' has led industry insiders to exclaim: "This is a dual test of operator skill and equipment calibration."
Comparison perspective: traditional mechanical drilling vs. laser drilling
Mechanical drilling methods often cause high breakage rates—up to 20%—due to the physical contact pressure. In contrast, laser drilling, through non-contact cutting, reduces this rate to less than 5%. This data comes from internal testing reports of a well-known display manufacturer, clearly demonstrating the superiority of laser technology.
Future outlook: Prologis and industry development trends
Prologis has begun developing integrated real-time monitoring systems that use optical sensors to feedback and adjust laser parameters promptly, further ensuring safety and quality in ultra-thin glass processing. Additionally, combining nano-level polishing technology aims to achieve higher precision holes and better edge quality.
Honestly, who wouldn't want a machine that can process with precision without damaging these fragile, 'as thin as cicada wings' materials?
