What exactly is a ceramic substrate?

Latest Updated:12/01/2006

Question:

The condition described in the absolute maximum rated total power dissipation for SC-62 products says when mounted on ceramic substrate, but what exactly is a ceramic substrate?

Answer:

A ceramic substrate is formed by shaping a material such as ceramic in the form of a plate and then firing it to harden it. Since ceramic substrates offer excellent heat dispersion characteristics compared to glass epoxy substrates, they are often used for comparatively large-power ICs such as hybrid ICs.
