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

The purpose of this is the resistance of
the device to sudden extreme changes
in high and low temperature.
This test intended to determine the
thermal characteristic resistance
of the device to sudden exposures
at extreme changes in temperature
when soldering the lead wire.
This test intended to see soldering well
performed or not.
