High-power Al2O3 Alumina Ceramic Circuit Board

Ceramic circuit boards are different from traditional FR-4 (plastics). Ceramic materials have good high-frequency performance and electrical properties, and have high thermal conductivity, excellent chemical stability and thermal stability, and other properties that organic substrates do not have. It is an ideal packaging material for a new generation of large-scale integrated circuits and power electronic modules. Therefore, in recent years, ceramic circuit boards have received extensive attention and rapid development.

DBC Process Capability and Specification of DBC ceramic substrates

The prime advantages of DBC substrates

1. Higher thermal conductivity, especially aluminum nitride DBC Ceramic Substrate is up to 180 W/k.m
2. Perfect matching thermal expansion coefficient that is similar of the Si chips in the high-power modules
3. Stronger and lower resistance metal film, copper is one of best conductor in the electrical fileds
4. The solderability of the substrate is good, and it's suitable for the operation under very high temperature
5. Good insulation, it's a ideal option for using in high-voltage and high-current application
6. Small high frequency loss because of the direct bonded copper file on ceramic substrates
7. It does not contain organic ingredients, is resistant to cosmic rays, has high reliability in aerospace and has a long service life
8. The copper layer does not contain an oxide layer and can be used for a long time in a reducing atmosphere
