stamping ceramic substrate electronic base board
Reputation depends on quality, quality comes from Hard!
Ceramic substrates are currently mainly used in the field of medium and low power, such as
General-purpose power electronics, concentrating solar energy, Peltier components (thermoelectric semiconductor refrigeration devices), automotive application semiconductor modules, etc. AlN ceramic materials are one of the few non-metallic materials with high thermal conductivity. The thermal conductivity of AlN ceramic substrates can reach 150~230W/(m·K), which is more than 8 times that of Al2O3. In addition, the coefficient of thermal expansion of AlN is (3.8 to 4.4) × 10 -6 / ° C, which is in good agreement with the thermal expansion coefficient of semiconductor chip materials such as Si, SiC and GaAs. There are a number of companies in Japan that develop and produce AlN ceramic substrates such as Jingtao, Japan Special Ceramics, Sumitomo Metal Industries, Fujitsu, Toshiba, and Nippon Electric. The preparation of AlN powder, the core material of AlN ceramics, is complicated in preparation process, high in energy consumption, long in cycle and expensive. The domestic AlN powder is basically imported, and the batch stability and cost of raw materials have become the bottleneck manufacture of high-end AlN ceramic substrate materials in China.
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.
