Problem Title:
What are the differences between C,I, M and B products in a package?


Problem Description:
Urgency: Standard

What gives rise to the differences between C, I, M, and B
products in a package?	Are we using different materials for
these?


C, I, M products: These products use the same materials (die
and packages) and processes. What distinguishes them is the
testing temperature ranges that the various grades have to meet
to satisfy the speed/timing conditions.

B-grade Products: Products labelled as B-grade have undergone
the "M" temperature testing, and the prescribed Military
processing flows and screens. These flows (processing) subjects
B materials to special screening and inspections that the C, I,
M products do not go through.
