Overview<\/strong><\/p>

Custom Laser micro-machine system operating on a femtosecond pulsed laser. The short pulse length limits local heating effects reducing Heat Affected Zone (HAZ). Applicable in wide range of materials. Especially effective for ceramics, metals and selected Polymers.<\/p>

\u2022 Ceramics* : Alumina oxide, Aluminium nitride, etc
\u2022 Wafers*\u00a0 \u00a0 \u00a0: Silicon, Silicon Nitride, Silica (Glass), etc
\u2022 Polymers\u00a0 \u00a0: Polyamide, Kapton, PMMA etc.
\u2022 Metals*\u00a0 \u00a0 \u00a0: Stainless Steel, Copper, Aluminium etc.<\/p>

We routinely perform and achieve the following precision:
1. 15 micron Percussion holes on ceramics, thin metals and silicon wafers with precision of <1 micron for ceramics.
2.\u00a0 30 micron minimum Circular holes on ceramics, thin metals and silicon wafers with highest precision of <1micron for\u00a0
\u00a0 \u00a0 \u00a0ceramics.
3.\u00a0 Smallest feature size > 20 microns with precision 1 micron on metal sheets, ceramics and polymers.
4.\u00a0 Dicing of Silicon wafer up to 750um thick with negligible dust on surface.<\/p>
