What Does LTCC Mean?
LTCC stands for Low Temperature Co-fired Ceramic. It is a material and manufacturing platform used to build compact multilayer electronic structures by printing conductors and circuit features on unfired ceramic tape, stacking the layers and firing them together.
The technology enables integration from material and circuit to package and system, supporting smaller, more integrated and modular electronic products.
Where It Is Used
- ✓RF front ends — low-loss dielectric systems for high-frequency circuits
- ✓Automotive electronics — stable ceramic material platforms for demanding modules
- ✓High-density packaging — multilayer interconnection and functional integration
- ✓Ceramic microsystems — compact three-dimensional ceramic structures
