Alumina ceramic substrate

The benefits of alumina ceramic substrates Alumina ceramic substrates have low communication loss – the dielectric constant of the ceramic material itself makes signal loss smaller. High thermal conductivity – the thermal conductivity of alumina ceramics is 15-35 w/mk, and the heat on the chip is directly conducted to the ceramic sheet without an insulating layer, which can achieve relatively better heat dissipation. A more matching thermal expansion coefficient – the material of the chip is generally Si (silicon) GaAS (gallium arsenide), and the thermal expansion coefficient of the ceramic and the chip is close, and it will not cause too much deformation when the temperature difference changes drastically, causing problems such as line de-soldering and internal stress.Alumina ceramic substrate

High operating temperature – Ceramic can withstand high and low temperature cycles with large fluctuations, and can also operate normally at high temperatures of 500-600 degrees. High Electrical Insulation – The ceramic material itself is an insulating material and can withstand high breakdown voltages. The above is what Pintejin Ceramics brings to you.
