50W ENIG ceramic circuit board Description Ceramic PCB is divided by material, there are 3 kinds, Al2O3 (alumina substrate), BeO and AlN. Let's talk about the AIN multilayer ceramic substrate, which has the advantages of high thermal conductivity and expansion coefficient matching Si. Disadvantages A very thin oxide layer on the surface will also affect the thermal conductivity, and strictly control the materials and processes. Multi-chip module (MCM) is developing rapidly as a new technology. With the continuous improvement of assembly density and the improvement of IC integration, the power density of MCM is increasing. In order to improve the heat dissipation of the device and increase the reliability, power is required The multilayer substrate used in MCM should have high heterothermal properties. The AIN multilayer ceramic substrate with high thermal conductivity fully meets the requirements of high-power MCM. FAQ Q. What file formats do you accept for FPC and assembly? A.
