Ceramic Package

It is material made of the mineral such as alumina or zirconia sintered under high temperatures. It is used as the casing for the sensor, the high frequency part, the high power LED, the medical electronic part and the military electronic part. Since it is highly wear resistant, heat resistant, EMF shielding and corrosion resistant, it is used in highly reliable electronic parts.

Ceramic Package Features and Advantages

  1. In general, it is used in applications required of high performance and reliability.
  2. It is has high hardness and high modulus of elasticity, it is highly corrosion resistant and highly wear resistance and has a relatively low thermal expansion coefficient.
  3. It has good high frequency properties, it is highly heat resistant and it is relatively easy to implement various temperature properties.
  4. As it does not have polarity, it is favorable for board mounting.
  5. It is increasingly used as set products such as mobile communication devices and digital home appliances which are digitalized, use higher frequency and become smaller.
