Alumina Ceramic electronic heat sink sheet substrate
Reputation depends on quality, quality comes from Hard!
Ceramic Substrate:
Liquid heat sinks are suitable for high power applications such as laser diodes, data centers, direct cooling power modules, high brightness LEDs or solar arrays (CPV), which are more than four times more efficient than conventional liquid cooling module structures. The aluminum nitride layer plays a role in insulating the circuit of the laser diode from the cooling water channel. Silicon Nitride Ceramics have many excellent properties such as high hardness, high strength, small thermal expansion coefficient, low temperature creep, good oxidation resistance, good thermal corrosion resistance and low friction coefficient. They are the best structural ceramic materials with comprehensive performance. The theoretical thermal conductivity of single crystal Silicon Nitride is up to 400 w/(m·K), which has the potential to be a highly thermally conductive substrate. In addition, the linear expansion coefficient of silicon nitride is well matched with semiconductor materials such as Si, SiC and GaAs, which makes silicon nitride ceramics an extremely attractive substrate material for high-strength and high thermal conductivity electronic devices. See the comparison of mechanical properties of silicon nitride, aluminum nitride and Alumina Ceramics.
Application:
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.
