Press molding aluminum nitride (ALN) ceramic

Aluminum nitride ceramics, as a high-performance ceramic material with high thermal conductivity, electrical insulation and mechanical strength, are widely used in electronics, aerospace, chemical and other fields. In the preparation process of aluminum nitride ceramics, forming technology is one of the key links, which affects the performance and quality of ceramic materials. At present, tape casting, injection molding and compression molding are commonly used molding methods in the preparation of aluminum nitride ceramics. Press molding technology is a more traditional molding method, which is mainly applicable to the preparation of aluminum nitride ceramic products with simple shapes and low dimensional accuracy requirements. The technology is based on mixing aluminum nitride powder with the appropriate amount of organic additives and placing it into a mold, using external pressure to make the powder particles rearranged and tightly combined to form a dense billet.

Hot press black aluminum nitride (ALN) ceramic

With the rapid development of microelectronics technology, the requirements of the device toward the direction of large capacity, high density, high speed, high power output, more and more complex devices on the substrate and packaging materials for heat dissipation put forward more and more high requirements. Traditional resin substrates and alumina ceramic substrates, the highest thermal conductivity are only 30w/(m-k) or so, far from meeting today's device heat dissipation requirements. In addition, ordinary aluminum nitride (aln) ceramic bending strength is generally less than 400mpa, limiting the industrial application of aluminum nitride (aln) ceramics. In contrast, hot-pressed aluminum nitride (aln) ceramics have both high thermal conductivity and high flexural strength properties, which have important application prospects.
