Default Re: Plastic or ceramic ICs?

Mainly reliability - ceramic for e.g. military/aerospace or other applications requiring high reliability. Also ceramic has higher thermal conductivity so higher power / faster clock rates.

For 7400/4000 series, plastic is plenty good enough for consumer applications.
