A family's day with
Tungsten
He is tired and wants to take a nap,
but the presentation for the business meeting needs to be refined. So he opens
his bag and looks for the laptop. Some music from the iPod will make the burden
of working less hard. All these electronic devices contain printed circuit
boards. During the production cycle, these circuit boards are brought in shape
by the use of Cemented Carbide routers and drilled with Cemented Carbide micro drills, sometimes not larger than 0.1 mm
in diameter.

circuit board) machining and the latest generation of micro drills in comparison
to a paper clip and a lead refill

These drills are operated at rpm’s up
to 350,000 and drill several thousand holes in the highly abrasive boards. The
integrated circuit chips in these electronic devices use Tungsten as conducting
plug or wire and Tungsten Silicide as gate material. Also displays used in the
equipment need Tungsten-Molybdenum alloys for production.
Finally we hope the father managed to
refine his presentation and had a good and successful business day.
