Abstract
One embodiment includes an electronic assembly having a first printed circuit board (PCB) and a second PCB. The second PCB has at least two processors and is coupled to and disposed on a first side of the first PCB. A thermal dissipation device dissipates heat away from the processors. First and second power modules are coupled to and disposed on a second side of the first PCB, the first and second power modules providing redundant power to the two processors on the second PCB.
Claims12
An electronic assembly, comprising:
- a first printed circuit board (PCB);
- a second PCB having at least two processors, the second PCB being coupled to and disposed on a first side of the first PCB;
- a thermal dissipation device for dissipating heat away from the processors;
- and
- first and second power modules coupled to and disposed on a second side of the first PCB, the first and second power modules providing redundant power to the two processors on the second PCB, wherein the first and second power modules are separated and supply redundant power such that upon failure of the first power module, the second power module provides power for both power modules to the two processors, and each of the first and second power modules connects to the second side of the first PCB in a vertically stacked configuration.
An electronic assembly, comprising:
- a first printed circuit board (PCB);
- a second PCB including plural processors and being connected to a first side of the first PCB;
- a thermal dissipation device that dissipates heat away from the plural processors;
- and
- first and second power modules connected to and disposed on a second, bottom side of the first PCB in a vertically stacked configuration, the first and second power modules are separated and provide redundant power to the plural processors such that the second power module provides power for the plural processors upon failure of the first power module.
