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

Description

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

Solution

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) subject B materials to special screening and inspections that the C, I, M products do not go through.
