Alumina (Al2O3) Ceramic Substrates for Resistors

Alumina Substrates

Alumina is the most commonly used technical ceramic material. Thanks to its very good electrical insulation, dielectric strength, and high-temperature resistance up to 1500 °C, Alumina Ceramic is ideal for electrical applications and high-temperature applications.

Alumina ceramics feature:

  • Good mechanical strength
  • Good heat conductivity and fire resistance
  • Good corrosion and wear resistance
  • Very good electric insulation

The alumina substrates also possess several unique features:

  • Good surface with high smoothness/flatness and less porosity
  • High resistance to heat shock
  • Low warpage and camber
  • Stable in very high temperature and corrosive chemical
  • Very stable breaking strength and shape/dimension variance

Applications:
Network resistor, Chip resistor, Chip resistor array, Thick-film hybrid IC, Thin-film hybrid IC, General isolator
