high temperature grinding Al2O3 machining ceramic tube
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
The thermal expansion coefficient of the ceramic substrate is close Silicon Carbide Ceramic to that of the silicon chip, which can save the Mo layer of the transition layer, save labor, materials, and reduce costs;
Reduce solder layer, reduce thermal resistance, reduce voids, and improve yield;
The line width of the 0.3mm thick copper foil is only 10% of the ordinary printed circuit board under the same current carrying capacity;
Excellent thermal conductivity makes the chip package very compact, which greatly increases the power density and improves the reliability of the system and device;
Ultra-thin (0.25mm) ceramic substrate can replace BeO, no Ceramic Disc environmental toxicity problem;
The current carrying capacity is large, the current of 100A continuously passes through the copper body of 1mm width and 0.3mm thickness, and the temperature rise is about 17°C; the current of 100A continuously passes through the copper body of 2mm width and 0.3mm thickness, and the temperature rise is only about 5°C;
Low thermal resistance, thermal resistance of ceramic substrate of 0.6×mm thickness of 10×10mm ceramic substrate is 0.31K/W, thermal resistance of ceramic substrate with thickness of 0.38mm is 0.19K/W, heat of ceramic substrate with thickness of 0.25mm The resistance is 0.14K/W.
High insulation withstand voltage to ensure personal safety and equipment protection.
New packaging and assembly methods can White Zirconia Ceramic be implemented to make the product highly integrated and compact. It has high mechanical strength and can be used as a supporting member in addition to components. It has good processability and high dimensional accuracy; it is easy to achieve multi-layering;
The surface is smooth, free of warpage, bending, microcracks, and the like. Good chemical stability; easy metallization, strong circuit pattern and adhesion;
Non-hygroscopic; oil-resistant, chemical-resistant; a-ray release is small;
The substances used are non-polluting and non-toxic; the crystal structure does not change within the temperature range of use;
Rich in raw materials; mature technology; easy to manufacture; low price.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
