ABSTRACT:
A thermal core (10) comprising a graphite layer (12) held between two molybdenum layers (14) for dissipating heat from a plurality of chip carriers 22. Core 10 has the ability to withstand excessive vibrational loads while being light weight. Bonding molybdenum/graphite/molybdenum layers (12, 14) creates a core (10) having an increased stiffness factor which surpasses military vibrational requirements. By using a titanium layer (16) to braze graphite layer (12) and molybdenum layers (14), plating for preventing corrosion attack is not necessary.
