Substrates
machined by Laser
Aluminium-Oxide-Ceramic
Aluminium-Nitride-Ceramic
For
this products we confirm RoHS-conformity
By
Laser, we can realize each profile fron wafers until a maximum
thickness of 1,5 mm resp. in case of round washers 1mm within
the below showed total dimensions.
Beside Prototypes and small Series, we also are able to
deliver large Quantities within a short Time. |
