WebSep 1, 2002 · Figure 1 shows approximately 100-µm-diameter exit holes in borosilicate glass drilled with an excimer laser. There are several ways to minimize these effects. First, it is possible to slow the drilling process by reducing the energy and/or repetition rate when nearing the end point so that the minimum fluence is used for final material removal. Web2.1.1. Mechanical Drilling. Mechanical drilling is the most conventional and relatively low-cost method to drill micro-holes in glass. Most often, peck drilling (depth of cut is sub-divided into small drilling cycles [ 22 ]) is …
