ceramic laser cutting substrate insulating sheet
Reputation depends on quality, quality comes from Hard!
Cerium oxide is a rare ceramic material with high electrical resistance and high thermal conductivity. Its thermal conductivity at room temperature can reach above 250W/(m·K), even comparable to metal materials. Can be used for high performance, high frequency, large Power electronics. The preparation of high-performance BeO ceramics generally uses MgO-Al2O3-SiO2 sintering aids, and studies have shown that doping 0.1% (mass ratio) of Tb4O7 can improve the thermal conductivity of BeO ceramics. CeO2 and Nd2O3 can increase the density of BeO ceramics. Alumina Ceramics is the most mature ceramic substrate material in the current manufacturing and processing technology, and its main component is α-Al2O3. According to the different Al2O3 content, it is divided into 75 porcelain, 85 porcelain, 95 porcelain and 99 porcelain. Al2O3. Ceramics have the advantages of low dielectric loss, high mechanical strength and good chemical stability. Although Al2O3 ceramics are currently the most mature ceramic substrate materials, their thermal conductivity is low, such as 99 porcelain Al2O3. heat. The conductivity is only 29W/(m·K). In addition, the thermal expansion coefficient of Al2O3 is quite different from that of semiconductor chip materials such as Si and SiC, and it is easy to be tired in the hot and cold cycle.
The role of ceramic substrate ceramic substrate according to the field of ceramic substrate application, is divided into HIC (hybrid integrated circuit) ceramic substrate, focusing potentiometer ceramic substrate, laser heating fixing ceramic substrate, chip resistor substrate, Network resistor substrate, etc.; according to different processing methods, ceramic substrates are divided into two types: molded tablets and laser scribe films. The ceramic substrate in the chip resistor substrate is a part of the chip resistor. The upper layer of the substrate is coated with different semiconductor materials, and then copper is plated on both ends for soldering. The biggest advantage of the whole resistor is that the volume can be made very well. small.
