Product Description

Review material position, substrate forms and processing scope.
AlN substrates prepared for thick-film circuit processing where thermal management and electrical insulation are required.
Thermal conductivity varies with grade and formulation. Higher-conductivity options are selected when thermal modeling justifies them.
Custom outlines and surfaces are reviewed with the grade and assembly process.
Published numerical values are typical references. Final specifications remain subject to material grade, geometry, supplier capability and agreed test method.
