"Popovkin said that some microchips used on the craft were imported
and possibly of inadequate quality to resist radiation. He did not
specify where the chips were manufactured.
"Yuri Koptev, a former space agency head who led the Phobos-Ground
investigation, said 62 percent of the microchips used in the probe
were "industrial" class, a less-sophisticated level than should be
used in space flight."
How long has Russia been using I class chips, rather than S class
chips, in its spacecraft, and
do they use only S chips in manned craft?
What does SpaceX use?
