Split core circuit module
View Patent ↗Flexible circuitry is populated with integrated circuitry (ICs) disposed along one or both major sides. Contacts distributed along the flexible circuitry provide connection between the module and an application environment. A rigid substrate configured with wings diverging from a central axis to create, preferably, a ‘V’-shaped structure provide supportive structure for the populated flex circuitry that is wrapped about an edge of the substrate.
1. A circuit module comprising:
a rigid substrate having a central leg portion with an edge and first and second wings, the wings diverging from each other and the central leg portion extending therfrom to form a ‘Y’-shaped structure; and
a flex circuit having first and second sides, the first side of the flex circuit having plural contacts adapted for connection to a circuit board socket and one of the first and second sides of the flex circuit being populated with plural memory CSPs, the flex circuit being disposed about the edge of the rigid substrate to place the first CSP-bearing portion alongside at least one of the wings of the substrate and contacts of the plural contacts being adjacent to both sides of the central leg portion of the rigid substrate.
2. The circuit module of claim 1 in which the flex circuit is populated with CSPs along its first and second sides.
3. The circuit module of claim 1 in which the rigid substrate is comprised of thermally conductive material.
4. The circuit module of claim 1 in which the rigid substrate is comprised of aluminum.
5. The circuit module of claim 1 in which the rigid substrate is comprised of copper.
6. The circuit module of claim 1 in which the rigid substrate is comprised of non-metallic material that is thermally-conductive.
7. The circuit module of claim 1 further comprising a first heat radiating portion in thermal connection with the first wing of the substrate.
8. The circuit module of claim 1 further comprising thermal members disposed along outer sides of the circuit module.
9. The circuit module of claim 1 further comprising a cooling component disposed in a channel formed by the first and second wings of the substrate.
10. The circuit module of claim 9 in which the cooling component includes at least one cooling fluid conduit.
11. A circuit module comprising:
A rigid substrate having a central leg portion with an edge and first and second wings, the wings diverging from each other, and the central portion extends therefrom to form ‘Y’-shaped structure; and
a flex circuit having plural edge connector contacts and first and second sides populated with chip scale packaged ICs, the flex circuit being disposed about the rigid substrate to place areas of the first and second sides that bear the chip scale packaged ICs along the first and second wings of the rigid substrate.
12. The circuit module of claim 11 in which the flex circuit is populated with at least one advanced memory buffer.
13. The circuit module of claim 11 in which the rigid substrate is comprised of thermally-conductive material.
14. The circuit module of claim 11 further comprising a first heat radiating member in contact with top surfaces of at least some of the chip scale packaged ICs populating the flex circuit.
15. The circuit module of claim 14 further comprising a second heat radiating portion in contact with top surfaces of at least some others of the chip scale packaged ICs populating the flex circuit.
16. The circuit module of claim 14 further comprising a first mount piece securing the first heat radiating member in relation to the substrate.
17. The circuit module of claim 14 further comprising a cooling component mounted in a channel formed by the first and second wing portions of the substrate.
