but military sales growth was higher.
“We estimate that the military/aerospace market accounts for
about 27 percent of the total PCB market in North America,” said
Sharon Starr, IPC director of market research. “Based on new
data, IPC is updating its market size estimates for rigid PCBs, flexible circuits, the mil/aero and medical vertical markets, and the
prototype market.”
PICMG Ratifies MicroTCA.2 Specification for
Rugged Industrial and Military Applications
PICMG has adopted the Hybrid Air/Conduction Cooled MicroTCA (MicroTCA.2) specification. The PICMG MicroTCA.2 specification addresses the needs of severe shock, vibration and thermal
environments typical of many military air, land and sea as well as
rugged industrial applications. The specification defines a modular
open systems approach for hardened hybrid air/conduction cooled
computer systems. It was developed based on key input from military vendors such as BAE Systems, and includes well-defined test
procedures for a consistent reading of vendor compliance.
MicroTCA.2 modules of all power levels benefit from the hybrid
air/conduction cooling (hybrid cooling) approach, in which conduction allows thermal sharing among modules and with the chassis. This thermal sharing effect allows additional surface area to
be exposed to the airflow through the chassis to more effectively
dissipate the system’s total thermal load.
Forced-air convection yields the dominant cooling effect in MicroTCA.2 systems, yet there is a significant secondary conduction
cooling benefit associated with the module clamshell and innovative wedge lock designs. By taking advantage of complementary
conductive heat transfer through finned clam-shelled module
surfaces and aluminum chassis sidewalls, as well as heat sharing
between adjacent chassis slots, the MicroTCA.2 hybrid cooling
solution effectively provides increased thermal margin over other
MicroTCA modes in environments with higher ambient air temperature or decreased airflow.
For example, at a flow condition of 6.7 CFM per slot, an AdvancedMC Single Module dissipating 51.6 W of power recorded a
6.6°C reduction in component temperature, a 33 percent component temperature benefit, using the MicroTCA.2 hybrid cooling
approach compared to the performance of a standard MicroTCA.0/MicroTCA.1 forced air-only solution.
