Abstract:
1. A circuit module comprising: a rigid substrate comprised of thermally conductive material and having first and second opposing lateral sides and a bottom edge; and a flex circuit having multiple conductive layers and a mounting portion and a substrate transit portion, the substrate transit portion having a row of voids, the mounting portion having more conductive layers than does the substrate transit portion, the flex circuit having a first side and a second side with the first side having plural edge connector contacts for connection of the circuit module to an edge connector, the first side having mounted on the mounting portion of the flex circuit, a first set of CSPs (chip scale packaged devices), and the second side having mounted on the mounting portion of the flex circuit, a second set of CSPs (chip scale packaged devices), the substrate transit portion being disposed about the bottom edge of the rigid substrate to expose on the outside of the circuit module the plural edge connector contacts and the first set of CSPs while disposing the second set of CSPs between the flex circuit and at least one of the first or second opposing lateral sides of the rigid substrate.
