LTCC Substrates

LTCC Substrates

Micro Systems Technologies (MST) offers highly reliable substrates utilizing LTCC (Low Temperature Co-fired Ceramic) technology. The LTCC technology provides excellent RF and microwave performance characteristics, and allows co-firing with highly conductive metals such as gold and silver. The superior mechanical and electrical properties, and the ability to embed passive components make MST's LTCC substrates ideal for high frequency applications.

LTCC substrates are housed in high-frequency low loss sensor packages with multi-chip modules. Features include multilayer technology (up to 20 layers), gold and silver based metallization systems, fine line patterning, and embedded resistors, capacitators, inductors, and strip lines. These substrates have a high frequency performance capabilities up to 90 GHz through the use of low loss ceramics.

Key LTCC Substrate Features:

  • Maximum substrate size: 4“ x 5“
  • Tape thickness: 95 μm, 135 μm, 204 μm
  • Flexural strength: 320 MPa
  • Thermal coefficient of expansion: 5.8 ppm/K
  • Thermal conductivity: 3 W/mK
  • Adjusted thermal expansion coefficient to Si and GaAs
  • Thermal vias for heat dissipation
