What is the LTCC?
How does it compare to Aluminium Oxide (Al2O3) and PTFE technologies?

What are the typical applications?
Commercial Military

Design Tool Issues?
Are there any? ….. Yes!

LTCC, PTFE and HT Ceramic Technology
LTCC
Conductors and ceramic are shaped / machined / formed at the same time Supports multi-layer designs Allows many forms of component attachment Very compact Good thermal properties

PTFE
Depletive process … take pre-plated material and remove unwanted regions No simple way to combine integrated resistors Excellent microwave performance (Duroid style boards - FR4 has limitations) Holes drilled before and after processing for PTH & NPTH Bonding SMDs … 0402 easy ... Semiconductor
