Micro-channels in sapphire
This micro-channel, laser milled into sapphire, is 90 µm deep by 75 µm wide. Note the square profile and flat bottom shown in the end view. If you’d like more…
Micro-soldering
These 50 µm wide leads are laser soldered onto a thin metalized layer deposited on a ceramic substrate. If you’d like more information on this project or if you’re interested…
Micro-drilling glass
For this project, Precision MicroFab drilled a hole array in 500 μm thick borosilicate glass using an ArF excimer laser with a wavelength of 193 nm. Each hole had a…

Laser welding plastic
For this project, Precision MicroFab welded plastic for a cell phone display. To create this lap weld, we used an infrared laser and some specialized fixturing to transmit through a…
Laser welding metal
This video shows components made from a sintering process, laser welded together: The weld bead is 100 μm wide and 2 mm long. The welds were completed with minimal oxidation…
Blind micro-holes in sapphire
For this project, which was intended for a fiber optic application, we drilled a series of five by five blind micro-hole arrays in a sapphire wafer using an ArF excimer…
