AlN hot plate
Our aluminum nitride hot plate is a heat element that can be printed and sintered in a pattern on sintered ceramics.
The heating pattern material can support a broad range of temperatures.
Power supply terminals and heating patterns have about the same thermal resistance and do not need special measures to protect the terminals.
