Description
This test is conducted for the purpose
of detemining the resisance of a part
in electrical and themal stressed.
The purpose of this is the resistance of
the device which is laid under ondition
of high temperature for hours.
The purpose of this is the resistance
of the device which is laid under
condition of low temperature for hours.
