When performing thermal analysis, signal-processing leader
Applied Signal Technology Inc., overcomes its manpower
limitations with a combination of Daat Research's consulting
services and their own in-house expertise. This resource
combination enables the company to develop multiple design
scenarios during their time-critical schedules, and shave months
off the thermal design effort.
Recently, Daat's thermal expertise was tapped for
schedule-critical modeling of a 19-inch data acquisition
chassis. Daat consultants created the base model, while Applied
Signal engineers performed design optimization.
In developing the thermal design, Coolit was used both at
component and system levels. Coolit also optimized heat sink
configurations for the ball grid arrays and pinpointed hot spots
within the system layout. The hot spots and their sources were
quickly revealed using Coolit's visualization tools. Air flow
animation showed that cooling air was not reaching critical
system components. Applied Signal engineers were able to correct
the problem by adding a series of baffles and plenums
to redirect the air flow. If the problem had not been found
until after the prototype was built, Applied Signal engineers
estimate that it could have delayed the project as much as 4
months.
