Aluminum nitride ceramic substrate 5050 , 0.5mm， ENIG

Ceramic PCB is a kind of thermal conductive organic ceramic circuit board with a thermal conductivity of 9-20W/m.k prepared at a temperature below 250℃ by using thermally conductive ceramic powder and organic adhesive.

With the gradual deepening of electronic technology in various application fields, the highly integrated circuit board has become an inevitable trend. The highly integrated package module requires a good heat dissipation system, while the traditional circuit board FR-4 and CEM-3 are in TC (thermal conductivity) The disadvantage of) has become a bottleneck restricting the development of electronic technology. In recent years, the rapid development of the LED industry has also put forward higher requirements for the TC indicators of its load-bearing circuit boards. In the field of high-power LED lighting, circuit substrates are often prepared from materials with good heat dissipation properties such as metals and ceramics. The thermal conductivity of high thermal conductivity aluminum substrates is generally 1-4W/M. K, and the thermal conductivity of ceramic substrates depends on the method of preparation. Different from the material formula, it can reach about 220W/M. K.
