Operating with Kontron heatspreader plate assembly

The operating temperature defines two requirements:

» the maximum ambient temperature with ambient being the air surrounding the module.

» the maximum measurable temperature on any spot on the heatspreader's surface

Test specification:

Temperature Grade

Validation requirements

Commercial grade

at 60°C HSP temperature the CPU @ 100% load needs to run at nominal frequency

Extended Temperature (E1)

at 75°C HSP temperature the CPU @ 75% load is allowed to start speedstepping for

thermal protection

Industrial grade by

Screening (XT)

at 85°C HSP temperature the CPU @ 50% load is allowed to start throttling for
thermal protection

Industrial grade by

Design (E2)

at 85°C HSP temperature the CPU @ 50% load is allowed to start throttling for

thermal protection


Operating without Kontron heatspreader plate assembly

The operating temperature is the maximum measurable temperature on any spot on the module's surface.

3.7.2

Humidity

» 93% relative Humidity at 40°C, non-condensing (according to IEC 60068-2-78)
