Demand
for smaller, higher power portable electronic
products is increasing. This translates to more
heat generation from electronics/batteries and
lower product heat dissipation capability. For
example, a cellular phone's thermal energy is
generated from electronic components during a
call. Other components such as the battery,
speaker and displays add to the system's total
thermal energy. CDMA and TDMA chipsets dissipate
thermal energy in high power consumption modes.
The heat dissipation transfers heat to the printed
circuit board as well as the housings of the phone
and battery pack. The battery pack generates heat
during discharge and also releases heat during
charge. Thermal management becomes even more
critical in larger applications such as laptop
computers and multi-unit battery chargers.
Motorola Product Testing Services provide thermal
simulation services and complete
problem-to-solution analyses that reduce product
design and prototyping cycle-time.
Our
capabilities include real-time and steady-state
modeling of:
-
Electronic components under various power
conditions
-
Component/printed circuit board design to achieve
optimum cooling of localized hot-spots
-
Temperature rise/distribution inside battery
packs, power supplies, chargers, and host devices
Thermal modeling can be essential to:
