PID7v-EC603e Hardware Specifications
PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
Figure 17 shows typical thermal performance data for the 21 mm CBGA package mounted to a test card.
Figure 15. CBGA Thermal Management Example
Temperature calculations are also performed identically to those in the previous section. For a power
consumption of 2.5 Watts in an ambient of 40
° C at 1.0 m/sec, the associated overall thermal resistance and
junction temperature, found in Table 13, will result.
Vendors such as Aavid Engineering Inc., Thermalloy, and Wakeeld Engineering can supply heat sinks with
a wide range of thermal performance. Refer to Section 1.8.6.1.2, “Thermal Management Example,” for
contact information.
