I guess I ought to know this but I never really found out: do companies
making regular commercial grade components usually test each component in
some way??! I never exepected that, I always thought that components for
non-critical applications (i.e. consumer electronics) were only spot
checked. I could understand maybe testing each one of the industrial or
aerospace/military versions for saftey's sake (although, you would also
expect the final equipment manufacturer to test each final device under
these circumstances).
