[Laser Micromachining Examples] Hole Processing Examples for Ceramic, Stainless Steel Plates, and Polyimide
Introducing three examples of micro-hole processing! You can also view processing photos from the left. ■ Hole processing of Φ1 mm in ceramic It can be seen that a vertical hole without taper has been made in a 1 mm thick ceramic (AlN). Additionally, there is no thermal impact, resulting in very clean edges. ■ Inverted taper hole processing This is a cross-section view of the hole processing results. Holes were processed in a 1 mm thick stainless steel plate. The photo shows the results of laser processing from left to right. The taper is controlled, resulting in an inverted taper on the laser emission side of the hole. ■ Hole processing of polyimide This is the laser entry side. Holes with a diameter of 25 µm have been processed. The edges are very clean, and there is almost no thermal impact. The material is 25 µm thick polyimide. This is applied to inkjet nozzles, processing over 1,000 holes per head.
