LTCC / HTCC
LTCC and HTCC material scope
LTCC uses ceramic and glass powders in a green-tape system that can be co-fired with conductors at a lower temperature than conventional alumina ceramics. HTCC is based mainly on alumina or aluminium nitride with organic binders and is co-fired at high temperature with refractory-metal conductors such as tungsten or molybdenum.
- LTCC shrinkage-control capability below ±0.3% for applicable systems
- Printing adaptability down to L/S 50 µm / 50 µm for applicable systems
- Custom size, thickness, shrinkage, color and physical properties
- Sheet or roll supply, prototype lots from 100 sheets, and matching printing or via pastes
