Patent ID: 7116557

Claim:
A printed circuit board assembly, comprising: a primary core of thermally conductive material; a two-tiered laminate substrate connected to the primary core, the two-tiered laminate substrate including a two-tiered cavity and electrically conductive circuit bonding pads connected to a circuit imbedded in a lower tier of the two-tiered laminate substrate; a circuit component disposed within the two-tiered cavity and connected to the primary core using a thermally conductive adhesive material, the circuit component including electrically conductive component bonding pads; flexible electrical interconnects connected to the electrically conductive circuit bonding pads and the electrically conductive component bonding pads; a conformal coating covering portions of the two-tiered laminate substrate, the thermally conductive adhesive material, the circuit component, the electrically conductive component bonding pads, the flexible electrical interconnects, the electrically conductive circuit bonding pads, and any portions of the primary core located in the two-tiered cavity and not covered by the thermally conductive adhesive material; and an encapsulating material filling the two-tiered cavity and encapsulating the thermally conductive adhesive material, the circuit component, the electrically conductive component bonding pads, the flexible electrical interconnects, and the electrically conductive circuit bonding pads.
