THERMAL MANAGEMENT FOR MICRO-ACE-TE (324-
BALL BGA PACKAGE)
Ball Grid Array (BGA) components necessitate that thermal
management issues be considered early in the design stage for
MIL-STD-1553 terminals. This is especially true if high transmit-
ter duty cycles are expected. The temperature range specified for
DDC's Micro-ACE-TE device refers to the temperature at the
ball, not the case.
All Micro-ACE-TE devices incorporate multiple package connec-
tions which perform the dual function of transceiver circuit
ground and thermal heat sink. Refer to the pinout tables for ther-
mal ball connection locations. It is mandatory that these thermal
FIGURE 17. BALL LOCATIONS FOR MICRO-ACE-TE (324-BALL BGA PACKAGE)
balls be directly soldered to a circuit ground/thermal plane (a cir-
cuit trace is insufficient). Operation without an adequate
ground/thermal plane is not recommended and extended expo-
sure to these conditions may affect device reliability.
The purpose of this ground/thermal plane is to conduct the heat
being generated by the transceivers within the package and con-
duct this heat away from the Micro-ACE-TE. In general, the cir-
cuit ground and thermal (chassis) ground are not the same
ground plane. It is acceptable for these balls to be directly sol-
dered to a ground plane but it must be located in close physical
and thermal proximity ("0.003" pre-preg layer recommended) to
the thermal plane.
