Contact Now High Purity Aluminum Nitride Aluminum nitride is a kind of advanced thermal conductivity material. It not only has the characteristics of ceramic insulation and low thermal expansion, but also has the thermal conductivity same as metallic copper and aluminium.
The metallization of aluminum nitride substrates by electroless copper plating is investigated. The AlN substrate is etched by 4% NaOH to study the correlation between the adhesion strength and the surface roughness of etched AlN substrate. Both the as-received nonpolished and the polished AlN are studied. For the nonpolished substrate, the adhesion strength increases from 130 kg/cm/sup 2/ for ...
4. Due to the difference in elastic modulus between copper and aluminum (the elastic modulus of copper is about 121000 MPa and the elastic modulus of aluminum is 72000 MPa), the corresponding warpage and shrinkage of the copper substrate will be smaller than that of the aluminum substrate, so the performance of copper-based PCB is more stable. 5.
