Excimer or TEA CO2? Drilling Marking PLD Research Wire Stripping

Micro-Machining

New micro-machining applications for this technology are explored everyday

The excimer and CO2 lasers are powerful industrial tools for the micro-machining of non-metals.

Masks of various shapes are often put in the beam and demagnified onto the component. The shape of the mask may be a rectangle or a round shape. Then X-Y tables can be used under CNC control to develop intricate shapes and contours. High speed CO2 lasers from lightmachinery can be used to cut and machine directly using a small focused spot.

EXCIMER AND CO2 LASER DRILLING

Very precise stripping from gold contact pads using an IPEX laser with a highly specialized Offner projection lens to pattern around a dozen devices in one go, with step & repeat for rows of devices. Edges are precise to <1.5µm, and note lack of debris using Coax He nozzle.
