Aluminum nitride ceramic tube components for communications application
Aluminum Nitride is one of the few materials that offers electrical insulation and high thermal conductivity. This makes AlN extremely useful in high power electronic applications in heat sink and heat spreader applications.
Aluminum Nitride (AlN) is an excellent material to use if high thermal conductivity and electrical insulation properties are required. Because of it’s qualities, it is an ideal material for use in thermal management and electrical applications.
Some common applications of Aluminum Nitride include the following:
Heat sinks & heat spreaders Electrical insulators for lasers Chucks, clamp rings for semiconductor processing equipment Electrical insulators Silicon wafer handling and processing Substrates & insulators for microelectronic devices & opto electronic devices Substrates for electronic packages Chip carriers for sensors and detectors Chip lets Collets Laser heat management components Molten metal fixtures Packages for microwave devices.
