Heat Stresses Electronics
Thermal Product Market Drivers

• Faster, more powerful devices produce more heat
• Higher density of electronic devices used in
  control applications
• Devices not hardened to environmental extremes

advancing technology

• Relationship between high performance
  temperatures reliability
• Customers seek insurance solutions to protect
  from costly shutdowns.

increased awareness of temperature vs.
reliability

Heat Stresses Electronics
Every 10C / 18F rise over room temperature cuts
electronic life expectancy in half

Sources of Damaging Heat
Heat can come from sources inside the cabinet . .
.
Indoor Industrial, Telecom Data Networking

• AC power supply
• Controllers (PLCs)
• Drives servos
• Transformers

• Radio equipment
• Battery back-up
• Server racks

• Processors
• Inverters
• Contactors relays

Sources of Damaging Heat
. . . outside the cabinet . . .
Indoor Industrial Telecom

• Welding process
• Paint oven

• Solar heat gain

• Blast furnace
• Foundryequipment

7
Sources of Damaging Heat
. . . from the electronics themselves . . .
More electronics going into same size or smaller
enclosures

• Datacom, telecom demanding higher performance
• More server functionsmean more heat

8
Sources of Damaging Heat
. . . as performance increases . . .

Effects of Damaging Heat
At extreme temperatures . . .

• Catastrophic failures
• Properties of silicone materials change
• Drive performance is de-rated
• I/C based devices may experience intermittent
  fluctuations in output and voltage migration
• Mean Time Between Failure (MTBF) decreases
  exponentially

11
Effects of Damaging Heat
What does it cost to shut down an automotive
assembly line for 1 hour?
12
Effects of Damaging Heat
Consider the costs associated with the following
. . .

• Productivity losses of plant/line shutdowns
• Labor
• Scrap
• Opportunity cost
• Component costs
• In warranty processing costs, labor
• Out of warranty out of pocket costs
• Material Labor
• Customer satisfaction costs
• Missed ship dates

13
