Blind Hole Machining
Blind holes are indentations of various shape and
depth that do not break through the workpiece.
The importance of blind hole machining is
increasing with the growing popularity of 3D
semiconductor packaging technology.
Lasers allow high precision milling of
blind holes with very high aspect ratio,
high edge quality, tightly controlled
depths, as well as creation of
tapered and square holes, all
with high throughput and
