really nice thing...
but seems they also don't drill the copper - they use co2 laser...
i wonder how it is possible to drill the resin and the glassfibers in a so
similar time that there is a smooth nice hole drilled.
(i also don't believe the yag laser milling will work, but that's only my
opinion.....)
